Starter concentration; titration vials up to 30mg available) - Starting dose: 25 units (0.15mg) twice weekly - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** Semaglutide is a GLP-1 receptor agonist. The same class of medication as Ozempic® and Wegovy®. Our compounded version pairs it with B12 to support energy levels during weight loss. **How it works:** It mimics the GLP-1 hormone your body naturally produces after eating. This tells your brain you're full, slows digestion, and helps regulate blood sugar. Leading to steady, sustainable weight loss. **Ideal for:** Adults with a BMI over 27 looking for pharmaceutical support alongside diet and exercise. Especially effective for those who struggle with portion control and cravings. **Dosing protocol:** 25 units subcutaneous injection twice weekly. Titrate up concentration as tolerated. 25 units = 0.25mL × 0.6mg/mL = 0.15mg per injection (starter vial). Hold or step back dose if nausea. Hydration & protein mitigate side effects. Full dose ladder (wholesale pharmacy passthrough, no markup): 1.2mg vial $25 · 2.4mg $30 · 4.4mg $42.68 · 6.8mg $65.96 · 8.2mg $79.54 · 11.2mg $108.64 · 12.5mg $121.25 · 15mg $145.50 · 20mg $194 · 30mg $291. **Benefits:** Appetite Suppression, Blood Sugar Control, Steady Weight Loss, Energy Support (B12) **Contraindications:** Not for those with personal/family history of thyroid cancer (MTC), MEN2 syndrome, active pancreatitis, or severe gastroparesis. Not suitable during pregnancy. **Stacks with:** lipo-b, lipo-c, aod-9604, ondansetron **Do not combine with:** tirzepatide-b12, semaglutide-glycine, semaglutide-microdose, tirzepatide-microdose --- ### Semaglutide/B6 + Glycine > Glycine-buffered semaglutide for patients who don't tolerate the B12 cofactor. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/semaglutide-glycine - Price: From $175/10mg (pharmacy wholesale, no markup) - Price note: Glycine carrier: reserved for patients with B-12 sensitivity, methylation issues, or histamine reactions. Higher carrier cost reflects formulation complexity, not the peptide itself. - Form: Injectable vial (10mg or 30mg total at 5mg-2.5mg/mL. Semaglutide + B6/glycine) - Starting dose: Per provider. Formulation reserved for B12-sensitive patients - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** Semaglutide compounded with B6 and glycine instead of B12. Identical active ingredient and weight-loss mechanism as Semaglutide/B12. Chosen when a patient has reacted to B12 or when a provider wants a cleaner cofactor profile. **How it works:** Same as Semaglutide/B12: mimics the GLP-1 hormone, suppresses appetite, slows gastric emptying. The B6/glycine carrier is pharmacologically inert with respect to weight loss. **Ideal for:** Adults indicated for compounded semaglutide who have a known B12 sensitivity or whose provider has specifically requested the glycine formulation. **Dosing protocol:** Subcutaneous injection twice weekly, matching standard semaglutide dosing. Provider titrates the dose up per patient response as tolerated. Two vial sizes: 5mg/2.5mg/mL × 2mL = 10mg total ($175) and 5mg/2.5mg/mL × 6mL = 30mg total ($425). **Benefits:** Appetite Suppression, Steady Weight Loss, B12-Free Cofactor, Glycine Buffer **Contraindications:** Same as Semaglutide/B12: avoid with thyroid cancer history, MEN2, pancreatitis, gastroparesis, or pregnancy. **Stacks with:** lipo-b, lipo-c, aod-9604, ondansetron **Do not combine with:** semaglutide-b12, tirzepatide-b12, tirzepatide-glycine, semaglutide-microdose, tirzepatide-microdose --- ### Semaglutide Microdose > A gentle once-weekly microdose of compounded semaglutide with vitamin B12, for a slower, lower-side-effect approach to GLP-1 support. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/semaglutide-microdose - Price: $25/1.2mg (pharmacy wholesale, no markup) - Form: Injectable vial (2mL, 0.6mg/mL, 1.2mg total. Compounded semaglutide + B12, not pure semaglutide) - Starting dose: 20 units once weekly (0.12mg microdose; range 0.1 to 0.25 mg/week) - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** This is compounded semaglutide, not pure semaglutide. A licensed U.S. 503A compounding pharmacy compounds it as semaglutide co-formulated with cyanocobalamin (vitamin B12) in the same vial, so every injection contains both. Semaglutide is a GLP-1 receptor agonist, the same active ingredient as Ozempic® and Wegovy®. It is the identical vial we prescribe as Semaglutide/B12, just drawn at a much smaller dose, so the vial lasts longer than standard dosing. **How it works:** It mimics the GLP-1 hormone your body makes after eating, telling your brain you're full and slowing digestion. At microdose levels the effect is milder and slower, which suits people who want to ease in or who are side-effect sensitive. The B12 is a carrier that supports energy levels during weight loss. It does not change how semaglutide works and does not add to weight loss on its own. **Ideal for:** Adults who want a gentle entry to GLP-1 therapy, are sensitive to side effects, or are microdosing for appetite and metabolic support alongside diet and exercise. Not for patients with a known B12 sensitivity, who should ask their provider about the B6/glycine formulation instead. **Dosing protocol:** 20 units subcutaneous injection once weekly. Titrate up as tolerated per provider. 20 units = 0.2mL × 0.6mg/mL = 0.12mg per injection (gentle microdose; range 0.1 to 0.25mg/week). Hold or step back dose if nausea. Hydration & protein mitigate side effects. **Benefits:** Gentle Microdose, Appetite Support, Fewer Side Effects, Compounded with B12 **Contraindications:** Not for those with personal/family history of thyroid cancer (MTC), MEN2 syndrome, active pancreatitis, or severe gastroparesis. Not suitable during pregnancy. Also avoid if you have reacted to cyanocobalamin (B12), since it is compounded into this vial. **Do not combine with:** semaglutide-b12, semaglutide-glycine, tirzepatide-b12, tirzepatide-glycine, tirzepatide-microdose --- ### Tirzepatide/B12 > Dual GIP/GLP-1 receptor agonist for enhanced metabolic support with B12. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/tirzepatide-b12 - Price: From $45/12mg (pharmacy wholesale, no markup) - Form: Injectable vial (2mL, 6mg/mL, 12mg total. Starter concentration; titration vials up to 180mg available) - Starting dose: 25 units (1.5mg) twice weekly - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** Tirzepatide is a dual GIP/GLP-1 receptor agonist. The same class as Mounjaro® and Zepbound®. It targets two hormonal pathways instead of one, often producing stronger results. **How it works:** By activating both GIP and GLP-1 receptors, tirzepatide provides a dual-action approach to appetite control, blood sugar regulation, and metabolic enhancement. **Ideal for:** Adults seeking maximum pharmaceutical weight management support, especially those who may have plateaued on single-pathway GLP-1 medications. **Dosing protocol:** 25 units subcutaneous injection twice weekly. Titrate up concentration as tolerated. 25 units = 0.25mL × 6mg/mL = 1.5mg per injection (starter vial). Hold or step back dose if nausea. Hydration & protein mitigate side effects. Full dose ladder (wholesale pharmacy passthrough, no markup): 12mg vial $45 · 24mg $90 · 34mg $127.50 · 44mg $165 · 56mg $210 · 66mg $247.50 · 30mg/3mL $112.50 · 52.5mg $196.88 · 60mg $225 · 180mg $675. **Benefits:** Dual-Pathway Action, Superior Weight Loss, Blood Sugar Regulation, B12 Energy Support **Contraindications:** Same as semaglutide: avoid with thyroid cancer history, MEN2, pancreatitis, gastroparesis, or pregnancy. **Stacks with:** lipo-b, lipo-c, ondansetron **Do not combine with:** semaglutide-b12, semaglutide-glycine, tirzepatide-glycine, semaglutide-microdose, tirzepatide-microdose --- ### Tirzepatide/B6 + Glycine > Glycine-buffered tirzepatide for patients who don't tolerate the B12 cofactor. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/tirzepatide-glycine - Price: From $225/60mg (pharmacy wholesale, no markup) - Price note: Glycine carrier: reserved for patients with B-12 sensitivity, methylation issues, or histamine reactions.

Formulation reserved for B12-sensitive patients - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** Tirzepatide compounded with B6 and glycine instead of B12. Identical active ingredient and weight-loss mechanism as Tirzepatide/B12. Chosen when a patient has reacted to B12 or when a provider wants a cleaner cofactor profile. **How it works:** Same as Tirzepatide/B12: dual GIP and GLP-1 receptor activation for appetite control, blood sugar regulation, and metabolic enhancement. The B6/glycine carrier is pharmacologically inert with respect to weight loss. **Ideal for:** Adults indicated for compounded tirzepatide who have a known B12 sensitivity or whose provider has specifically requested the glycine formulation. **Dosing protocol:** Subcutaneous injection twice weekly, matching standard tirzepatide dosing. Provider titrates the dose up per patient response as tolerated. Two vial sizes: 15mg-2.5mg/0.5mL × 2mL = 60mg total ($225) and 15mg-2.5mg/0.5mL × 6mL = 180mg total ($675). **Benefits:** Dual-Pathway Action, Superior Weight Loss, B12-Free Cofactor, Glycine Buffer **Contraindications:** Same as Tirzepatide/B12: avoid with thyroid cancer history, MEN2, pancreatitis, gastroparesis, or pregnancy. **Stacks with:** lipo-b, lipo-c, ondansetron **Do not combine with:** tirzepatide-b12, semaglutide-b12, semaglutide-glycine, semaglutide-microdose, tirzepatide-microdose --- ### Tirzepatide Microdose > A gentle twice-weekly microdose of compounded tirzepatide with vitamin B12, for a slower, lower-side-effect approach to dual-pathway GLP-1 support. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/tirzepatide-microdose - Price: $45/12mg (pharmacy wholesale, no markup) - Form: Injectable vial (2mL, 6mg/mL, 12mg total. Compounded tirzepatide + B12, not pure tirzepatide) - Starting dose: 5 units twice weekly (0.3mg/injection, 0.6mg/week microdose) - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** This is compounded tirzepatide, not pure tirzepatide. A licensed U.S. 503A compounding pharmacy compounds it as tirzepatide co-formulated with cyanocobalamin (vitamin B12) in the same vial, so every injection contains both. Tirzepatide is a dual GIP/GLP-1 receptor agonist, the same active ingredient as Mounjaro® and Zepbound®.

Generic Zofran orally disintegrating tablets. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/ondansetron - Price: $1.25/tablet (pharmacy wholesale, no markup) - Form: Orally disintegrating tablet (4mg × 30 tablets per pack) - Starting dose: 1 tablet (4mg) every 8 hours as needed for nausea - Beyond Use Date: N/A (manufactured drug, follow expiration on package) **What it is:** Ondansetron is the generic name for Zofran®. The orally disintegrating tablet (ODT) form melts on the tongue, no water needed. Useful when nausea is acute. Prescribed as an adjunct to GLP-1 therapy for patients who experience breakthrough nausea during dose titration. **How it works:** Ondansetron blocks serotonin (5-HT3) receptors in the gut and brain that trigger the nausea reflex. It does not treat nausea by sedating you. It interrupts the chemical signal directly. **Ideal for:** Patients on semaglutide or tirzepatide who experience nausea during the first 4 to 8 weeks of titration, or whenever a dose increase brings it back. Use as needed, not on a schedule. **Dosing protocol:** 1 tablet (4mg) dissolved on the tongue every 8 hours as needed for nausea. Maximum 3 tablets per 24 hours. Take 30 to 60 minutes before a GLP-1 dose if nausea is anticipated. **Benefits:** Fast-Acting, No Water Needed, Targets Nausea Pathway, Generic Pricing **Contraindications:** Avoid in patients with congenital long QT syndrome.

This troche dissolves under the tongue for patients who prefer an oral route over the injectable vial. **How it works:** It stimulates fat metabolism and inhibits lipogenesis (fat production). The sublingual troche is held under the tongue so a portion absorbs through the oral mucosa, avoiding a daily injection. **Ideal for:** Patients who want AOD-9604's targeted fat-loss support without injections. Works as part of a comprehensive weight management protocol. **Dosing protocol:** Dissolve 1 troche (300mcg) under the tongue once daily, Monday through Friday. Hold sublingually until fully dissolved; do not chew or swallow whole. **Benefits:** Targeted Fat Loss, No Needle, Sublingual, Daily Protocol **Contraindications:** Generally well-tolerated. Avoid during pregnancy. **Stacks with:** semaglutide-b12, bpc-157-caps, tesofensine **Do not combine with:** aod-9604 --- ### Lean Stack (SS-31/MOTs-C/Tesamorelin) > Three-peptide metabolic blend in one vial: tesamorelin for the growth hormone pathway, MOTs-C for metabolic signaling, and SS-31 for mitochondrial function. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/lean-stack - Price: $125/30mg (pharmacy wholesale, no markup) - Form: Injectable vial (5mL, 2mg-2mg-2mg/mL, SS-31 10mg + MOTs-C 10mg + Tesamorelin 10mg total) - Starting dose: 20 units (0.4mg SS-31 + 0.4mg MOTs-C + 0.4mg Tesa) - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** The current Lean Stack formula, compounded by a licensed U.S. 503A compounding pharmacy. It replaced the original four-peptide formula in September 2026: AOD-9604 and ipamorelin came out and SS-31 went in, so each of the three peptides covers a different pathway instead of overlapping. **How it works:** One injection covers three areas. Tesamorelin acts on the growth hormone pathway and has established activity on visceral fat. MOTs-C is studied for its role in cellular metabolism and energy use. SS-31 is studied for mitochondrial membrane stability, cellular energy production, and oxidative stress. **Ideal for:** Patients working on body composition who want growth hormone, metabolic, and mitochondrial support in a single daily injection, including patients who were on the original Lean Stack. **Dosing protocol:** 20 units subcutaneous injection daily for 5 days, 2 days off. 20 units = 0.2mL delivering SS-31 0.4mg + MOTs-C 0.4mg + Tesamorelin 0.4mg per injection. **Benefits:** Three Pathways, Visceral Fat Focus, Mitochondrial Support, Single Vial **Contraindications:** Combined contraindications of all three components.

By blocking this enzyme, it helps restore metabolic function in fat cells. **How it works:** NNMT is overexpressed in fat tissue and contributes to metabolic slowdown. By inhibiting it, 5-Amino-1MQ helps increase cellular energy production and fat metabolism. **Ideal for:** Those experiencing metabolic slowdown or looking to enhance fat metabolism alongside a healthy lifestyle. Often used as part of a comprehensive metabolic optimization stack. **Dosing protocol:** 20 units subcutaneous injection daily. 20 units = 0.2mL × 5mg/mL = 1mg per injection. 8 to 12 weeks duration, may be cycled or extended. **Benefits:** Metabolic Boost, NAD+ Support, Fat Cell Activation, Energy Production **Contraindications:** Limited data on long-term safety. Avoid during pregnancy. Discuss with provider if on metabolic medications. **Stacks with:** aod-9604, nad-plus-inject --- ### Tesofensine > A triple monoamine reuptake inhibitor that suppresses appetite through central nervous system pathways. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/tesofensine - Price: $2.25/cap (pharmacy wholesale, no markup) - Form: Capsule (500mcg) - Starting dose: 500mcg/day - Beyond Use Date: 180 Days from compounding (USP <795>) **What it is:** Tesofensine is a triple monoamine reuptake inhibitor originally developed for neurological conditions. It was found to have significant appetite-suppressing effects. **How it works:** By increasing levels of norepinephrine, dopamine, and serotonin in the brain, it naturally reduces hunger signals and can increase resting metabolic rate. **Ideal for:** Adults who need additional appetite control support. Often prescribed when GLP-1 medications alone aren't sufficient or aren't suitable. **Dosing protocol:** 1 capsule (500mcg) daily, taken in the morning. Do not exceed prescribed dose. **Benefits:** Appetite Control, Metabolic Boost, Oral Capsule, Triple-Action **Contraindications:** Not suitable for those with uncontrolled hypertension, cardiovascular disease, history of stroke, or anxiety disorders. Avoid with MAOIs. **Stacks with:** lipo-b, lipo-c **Do not combine with:** semaglutide-b12, tirzepatide-b12 --- ### Lipo-B (Cyanocobalamin/MIC) > A lipotropic injection combining cyanocobalamin (B12) with methionine, inositol, and choline for fat metabolism. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/lipo-b - Price: From $30/10ml (pharmacy wholesale, no markup) - Form: Injectable vial (10mL. Cyanocobalamin + methionine + inositol + choline) - Starting dose: Per protocol - Beyond Use Date: 60 Days from compounding (USP <797>) **What it is:** Lipo-B is a lipotropic injection containing cyanocobalamin (B12), methionine, inositol, and choline (MIC). These nutrients support your body's natural fat metabolism pathways. **How it works:** MIC compounds help your liver process fats more efficiently, while cyanocobalamin (B12) supports energy production. Together they optimize your body's fat-burning processes. **Ideal for:** Anyone on a weight management protocol who wants to support their body's fat metabolism. Excellent add-on to GLP-1 therapy or standalone for metabolic support. **Dosing protocol:** 1mL intramuscular or subcutaneous injection once weekly. **Benefits:** Fat Metabolism, Energy Boost, Liver Support, Affordable **Contraindications:** Generally very well-tolerated. Avoid if allergic to any component. Safe for most patients. **Stacks with:** semaglutide-b12, tirzepatide-b12, aod-9604 --- ### Lipo-C (Cyanocobalamin/MIC/L-Carnitine) > Enhanced lipotropic injection adding L-carnitine to cyanocobalamin and MIC for improved energy and fat transport. - URL: https://www.rxpepsdirect.com/peptides/weight-loss/lipo-c - Price: From $35/10ml (pharmacy wholesale, no markup) - Form: Injectable vial (10mL. Cyanocobalamin + methionine + inositol + choline + L-carnitine) - Starting dose: Per protocol - Beyond Use Date: 60 Days from compounding (USP <797>) **What it is:** Lipo-C builds on the Lipo-B formula by adding L-carnitine, an amino acid that helps transport fatty acids into mitochondria where they are burned for energy. **How it works:** L-carnitine shuttles fatty acids into your cells' energy factories (mitochondria), while MIC compounds and cyanocobalamin (B12) support overall fat metabolism and energy levels. **Ideal for:** Active individuals who want enhanced fat burning during exercise, or anyone looking for the metabolic benefits of Lipo-B with extra energy support. **Dosing protocol:** 1mL intramuscular or subcutaneous injection once weekly. **Benefits:** Enhanced Fat Burning, Mitochondrial Support, Energy Production, Exercise Recovery **Contraindications:** Generally well-tolerated.

Do not take methylene blue if you are taking any of the following: SSRIs, SNRIs, MAOIs, tricyclic antidepressants, lithium, tramadol, dextromethorphan, meperidine, triptans, St. John's Wort, or any other serotonergic medication. The combination can cause serotonin syndrome, which can be fatal. Tell every other prescriber you see that you are taking methylene blue. The most likely way this goes wrong is a clinician starting you on an antidepressant without knowing, and they have no reason to think of a blue capsule as an MAOI. Methylene blue is also contraindicated in G6PD deficiency, which carries a risk of hemolysis. G6PD status is confirmed with a simple blood test. Risk is higher in people of Mediterranean, African, or Southeast Asian descent. **Stacks with:** nad-plus-inject **Do not combine with:** SSRIs, SNRIs, MAOIs --- ### NAD+ Injectable > Injectable NAD+ dual-listed for its significant cognitive and neuroprotective benefits. - URL: https://www.rxpepsdirect.com/peptides/cognitive/nad-plus-inject-cognitive - Price: $100/1000mg (pharmacy wholesale, no markup) - Form: Injectable vial (10mL, 100mg/mL, 1000mg total) - Starting dose: 20 units (20mg) - Beyond Use Date: 90 Days from compounding (USP <797>) **What it is:** NAD+ is dual-listed here for its significant cognitive benefits.
