How does the Rx Peps Direct medical review work?
You complete a clinical intake form at rxpepsdirect.com/get-script. The form collects your medical history, current medications, and weight. A licensed nurse practitioner or physician assistant in your state reviews it. If you are a candidate for the protocol you selected, the provider issues a prescription. A licensed U.S. 503A compounding pharmacy prepares it and ships it FedEx overnight. Injectable peptides arrive pre-reconstituted and ready to inject in a reusable cooled travel case; oral capsules, nasal sprays, troches, and topicals ship ready to use.

Peptide therapy basics

What peptide therapy is, what peptides are used for, and how the safety and efficacy picture looks today.

What is peptide therapy?
Peptide therapy is the prescribed use of compounded peptide medications to address a clinically documented condition or goal. Peptides are short chains of amino acids that signal specific cellular processes such as appetite regulation, growth hormone release, tissue repair, or mitochondrial function. Rx Peps Direct providers prescribe peptide therapy for weight management, muscle and recovery support, longevity goals, cognitive function, and metabolic health when supported by your medical history. A fuller explainer is at rxpepsdirect.com/learn/peptide-therapy.
What are peptides used for?
Peptides are used for clinically documented conditions including weight loss (compounded GLP-1 medications such as tirzepatide and semaglutide), tissue repair and healing (BPC-157, TB-500, GHK-Cu), growth hormone deficiency and lipodystrophy (sermorelin, tesamorelin), cognitive support (Semax, Selank), and longevity-related goals (NAD+, MOTS-C, Epithalon). Each peptide targets a different cellular receptor or signaling pathway. A licensed provider determines which peptide, if any, fits your medical history and goals. Background reading is at rxpepsdirect.com/learn/what-are-peptides and the full catalog is at rxpepsdirect.com/peptides.
Is peptide therapy safe?
Peptide therapy from a 503A pharmacy is prepared under a patient-specific prescription. A licensed provider writes the prescription after a documented medical review. Each batch is sterility-tested and endotoxin-tested before release. Safety risk is concentrated in research-grade peptides sold without a prescription, where source, sterility, and identity are not verified. Rx Peps Direct only prescribes peptides that are prepared by a licensed 503A pharmacy with published Certificates of Analysis.
Does peptide therapy work?
Efficacy depends on the specific peptide and the condition. Compounded GLP-1s (tirzepatide, semaglutide) have published clinical trial data showing 15 to 22 percent mean weight loss over 72 weeks. Sermorelin and tesamorelin have FDA approval histories for growth hormone deficiency and HIV-associated lipodystrophy respectively. Other peptides such as BPC-157 and TB-500 have animal-model data and growing clinical use but limited large-scale human trials. Your provider will discuss what evidence supports the peptide they are considering for you.
Is peptide therapy FDA approved?
Some peptides Rx Peps Direct prescribes are FDA-approved branded drugs (sermorelin, tesamorelin) prescribed in compounded form for individualized dosing. Others are compounded under Section 503A of the Federal Food, Drug, and Cosmetic Act for patient-specific prescriptions. The 503A pathway is legal but does not require FDA approval of the specific compounded preparation. Safety and quality oversight comes from the pharmacy's state board of pharmacy and the prescribing provider. The approval status of each peptide is broken down at rxpepsdirect.com/learn/are-peptides-fda-approved.

Pricing and ordering

Flat $39 medical review, no membership, optional automatic refills, cash-pay only, and how refills work.

How does the $39 medical review work?
Rx Peps Direct charges one flat $39 fee per order. That covers the medical review: a licensed provider reviewing your intake, writing your script, and coordinating with the pharmacy. You can include up to 3 different peptides per order, so three peptides on one order is $39 total, not $39 each. No membership. Automatic refills are optional: they start only if you opt in, and you can turn them off any time from your dashboard. Full pricing is at rxpepsdirect.com/pricing and you can start an order at rxpepsdirect.com/get-script.
Do I need a subscription?
No. No membership. Automatic refills are optional. Each order is a $39 medical review that covers up to 3 different peptides, and you can simply order again when you need a refill. If you opt in to automatic refills, your next refill starts on its own, timed to your supply: each one is a single $39 medical review charged to your saved card, your provider still reviews every refill before anything ships, and you can turn automatic refills off any time from your dashboard. Nothing refills automatically unless you opt in. Start an order at rxpepsdirect.com/get-script.
Does Rx Peps Direct take insurance?
No. Rx Peps Direct is cash-pay only. Compounded peptide medications prepared under Section 503A are not covered by commercial or government health insurance. The $39 medical review and the per-dose peptide pricing shown on the peptides page is the full price you pay.
How many peptides can I include in one order?
You can include up to 3 different peptides in one $39 order. The fee is per order, not per peptide, so three peptides on a single order is $39 total. Most weight-loss patients order one peptide. Recovery and longevity patients often combine peptides such as BPC-157 with TB-500, or NAD+ with MOTS-C. Your provider will confirm the combination is clinically reasonable before issuing the prescription. Browse the full catalog at rxpepsdirect.com/peptides.
Can I add a peptide to my order after I submit it?
No. Orders are final once submitted. Peptides cannot be added, removed, or swapped after checkout, even minutes later. Every order goes to medical review exactly as it was placed. Before you submit, one $39 order covers up to 3 different peptides, so add everything you want to the same order rather than placing separate ones. To add a peptide after submitting, place a new order at rxpepsdirect.com/get-script. That new order carries its own $39 medical review.
How do refills work at Rx Peps Direct?
You log in at rxpepsdirect.com/dashboard and request a refill. Your assigned provider reviews the request, confirms you are still eligible, and writes a renewed prescription. Each refill is a new $39 medical review, and that single medical review fee still covers up to 3 different peptides on the same refill order. There is no pre-paid plan. Automatic refills are optional: if you opt in, at checkout or from your dashboard, each refill starts on its own, timed to your supply, with the same $39 medical review, and you can turn them off any time from your dashboard. The same peptide can be reordered 15 days after your last order of it was approved, or 21 days for tirzepatide and semaglutide.
How soon can I reorder the same peptide?
You can reorder the same peptide 15 days after your last order of it was approved, not sooner. Tirzepatide and semaglutide can be reordered 21 days after approval, and every tirzepatide and semaglutide product shares that one date. Injectable growth hormone peptides (sermorelin, CJC-1295/Ipamorelin, tesamorelin, and blends that contain one of them) also share one date. A different peptide, or a different form of the same one such as capsules instead of a vial, can be ordered at any time. If you try to reorder early, checkout shows the date you can come back, before any medical review fee is charged. Each order is sized to be taken as prescribed, so we do not fill extra or backup supply early, and that includes travel. A dose increase is different: your provider reviews it, and it is not held to this date.
Can I talk to a doctor before choosing peptides?
Yes. Guided Peptide Therapy pairs you with Dr. Christine Green, DNP, FNP-C, a nurse practitioner, for $99 a month at rxpepsdirect.com/guided. She builds your peptides, nutrition, training and recovery around your goals. You meet her on a 20-minute video visit every month. You send her a written check-in every two weeks, and you can message her any time. Members can be prescribed up to 10 different peptides a month, as she approves. Members pay no $39 medical review on their orders. Medication is billed separately by the pharmacy. You do not need to know which peptides you want before you start. Guided Peptide Therapy is open in 11 states. In every other state we serve, you can order with the $39 medical review.
Why is my state no longer available at checkout?
State availability is the overlap of two lists: the states a licensed U.S. 503A compounding pharmacy ships to and the states our prescribers hold active licenses in. Both lists change as licenses are added or renewed, so a state can appear or disappear over time. If your state dropped off after you ordered before, email support@rxpepsdirect.com and we will tell you if and when it returns.

Pharmacy, compounding, and quality

What 503A means, why Rx Peps Direct works with a licensed U.S. 503A compounding pharmacy, and how every batch is independently tested.

What is a 503A pharmacy?
A 503A pharmacy is a state-licensed pharmacy that compounds patient-specific prescriptions under Section 503A of the Federal Food, Drug, and Cosmetic Act. Compounding requires an individual prescription and a documented medical need. The 503A pharmacy Rx Peps Direct works with holds an active Texas license and prepares every Rx Peps Direct prescription.
What is the difference between a 503A and a 503B pharmacy?
A 503A pharmacy compounds individual patient prescriptions on demand. A 503B pharmacy is a registered outsourcing facility that compounds in bulk for clinics under stricter FDA cGMP oversight; the 503B mass-compounding pathway for GLP-1s ended on March 19, 2025. Rx Peps Direct works exclusively with a 503A pharmacy because every prescription is patient-specific.
Why does Rx Peps Direct work with a licensed 503A pharmacy?
The pharmacy is a 503A-licensed compounding pharmacy in Texas with a dedicated sterile compounding suite. Every batch is tested by Eagle Analytical Services for sterility (ScanRDI or Celsis) and bacterial endotoxin (USP <85>) before release. The pharmacy ships FedEx overnight in a reusable cooled travel case. Injectable peptides arrive pre-reconstituted with sterile syringes and alcohol swabs included at no additional cost; oral capsules, nasal sprays, troches, and topicals ship ready to use, no syringes needed. The pharmacy publishes every Eagle test report on the Rx Peps Direct site.
What is a compounded medication?
A compounded medication is one made to order by a licensed pharmacy from individual ingredients, against a patient-specific prescription. Compounding is used when a manufactured drug is unavailable, when a patient needs a different strength than what is commercially produced, or when a different combination of active ingredients is medically appropriate. Compounded medications prepared under Section 503A do not require FDA approval. Under Section 503A, a bulk ingredient generally must have a USP monograph, be a component of an FDA-approved drug, or appear on FDA's 503A bulks list.
How does Rx Peps Direct verify the peptides are sterile?
Every batch is tested by Eagle Analytical Services, an FDA-registered, A2LA ISO 17025-accredited independent laboratory, for sterility (ScanRDI or Celsis) and bacterial endotoxin (USP <85>). The Certificate of Analysis for every batch is published on the corresponding product page and at rxpepsdirect.com/quality. Every report is published; none are withheld.
What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a third-party laboratory report that documents the test results for a specific batch of medication. The COA shows the lot number, manufacturing date, sample identification, sterility result, endotoxin value with the USP limit, and the testing method used, plus a potency result under USP <621> on the select batches where that assay was run. Rx Peps Direct publishes the Eagle Analytical COA for every batch on the relevant product page and at rxpepsdirect.com/quality. You can verify the lot number on your shipping label against the published COA. A walkthrough of how to read one is at rxpepsdirect.com/learn/how-to-read-a-peptide-certificate-of-analysis.
Why does every tirzepatide and semaglutide option include B12 or glycine?
A licensed U.S. 503A compounding pharmacy compounds its GLP-1 medications with a carrier: cyanocobalamin (vitamin B12) or glycine with vitamin B6. This applies to every tirzepatide and semaglutide SKU we carry, including Tirzepatide Microdose and Semaglutide Microdose, which are the identical Tirzepatide/B12 and Semaglutide/B12 vials drawn at a smaller dose, not a pure or single-ingredient version. The carrier is a formulation choice by the pharmacy and does not change how tirzepatide or semaglutide works. B12 supports energy levels during a caloric deficit; the glycine variant exists for patients with B12 sensitivity or methylation concerns. A single-ingredient version is not part of the formulary, so choose the carrier that fits your history and ask your provider if you are unsure. The two carriers are compared at rxpepsdirect.com/learn/glycine-vs-b12-carrier.
Why are some peptides only available as blends?
Blends pair peptides whose mechanisms complement each other, like CJC-1295 with Ipamorelin for a stronger natural growth hormone pulse, or BPC-157 with TB-500 and KPV for overlapping repair and inflammation pathways. The pharmacy compounds the blend into one vial so the pairing ships at a fixed clinical ratio in a single injection. Where a molecule is clinically standard on its own, it is listed as a standalone. If you want a specific molecule outside its blend, message your provider through your dashboard at rxpepsdirect.com/dashboard and they will tell you whether a standalone or a different blend fits your case. The full catalog, including which molecules are available standalone, is at rxpepsdirect.com/peptides.

Logistics and support

Shipping, what arrives in the box, and how to reach a provider after your order ships.

How fast is shipping?
A licensed U.S. 503A compounding pharmacy ships via FedEx overnight in a reusable cooled travel case. Injectable peptides arrive pre-reconstituted and ready to inject, with sterile syringes and alcohol swabs included; oral capsules, nasal sprays, troches, and topicals ship ready to use. The pharmacy charges a $15 flat shipping fee per order, included on the pharmacy payment link and separate from the $39 medical review. The $15 covers the entire order, so it is the same whether you have one peptide on it or three.
What is included in the shipping box?
Every order ships in cold-chain packaging with a printed copy of the prescription label and Certificate of Analysis lot number, plus a printed protocol sheet for first-time patients. For injectable peptides, the box also includes the matching number of sterile insulin syringes (typically 31-gauge, 5/16 inch) and alcohol swabs, and the vial ships pre-reconstituted and ready to use; you do not need to mix anything or supply bacteriostatic water. Oral capsules, nasal sprays, troches, and topicals ship ready to use and do not include syringes.
Do I have to reconstitute the peptides or buy bacteriostatic water?
No. Every injectable peptide prepared by a licensed U.S. 503A compounding pharmacy ships pre-reconstituted and ready to inject; oral capsules, nasal sprays, troches, and topicals ship ready to use and never require reconstitution either. Bacteriostatic water itself is on an active ASHP-listed national shortage, so research-peptide buyers struggle to source it; Rx Peps Direct patients never need to. Injection technique is covered at rxpepsdirect.com/guides/how-to-inject-peptides.
What if I have side effects?
Message your provider directly through your dashboard at rxpepsdirect.com/dashboard. Rx Peps Direct providers respond to clinical questions within one business day and will adjust your protocol if needed. For an urgent reaction, call 911 or your local emergency room first, then notify your provider through the dashboard.
When will the pharmacy text me my payment link?
A licensed U.S. 503A compounding pharmacy texts a secure payment link within 24 business hours of your approval email. The text usually comes from a number you do not have saved, so check your filtered, blocked, or unknown-sender messages. If 24 business hours have passed with no text, contact the pharmacy using the details in your approval email, or reply to that email and we will chase it for you. You can check your order status any time at rxpepsdirect.com/dashboard. Your order does not ship until the pharmacy payment is complete.
What should I do if my package arrives warm or delayed?
Do not use the medication until a pharmacist has cleared it. Contact the pharmacy using the details in your approval email, with your order number and a note on how the package arrived. The pharmacist assesses whether the cold chain held and replaces the order if it did not. Also message your provider through your dashboard at rxpepsdirect.com/dashboard so your protocol timeline can be adjusted.
My prescription label says a different dose than the website. Which do I follow?
Follow the prescription label. The label is written for you specifically by your provider and the pharmacist, while website pages describe the standard protocol. If the two differ and you want to confirm why, message your provider through your dashboard at rxpepsdirect.com/dashboard before your next dose.
Can I get prescription documentation for travel?
Yes. Every shipment already includes the pharmacy label, which satisfies most domestic travel checks. For international travel, message your provider through your dashboard at rxpepsdirect.com/dashboard and we will email you a PDF with the prescriber, medication, dosage, and your name as the patient.
