Immune RecoveryTissue ProtectionNon-SuppressiveDual-Listed

What It Is

ARA-290 is dual-listed for its immune recovery properties. It activates repair pathways that support immune-mediated healing.

How It Works

Activates the innate repair receptor, supporting the immune system's role in tissue repair and recovery without suppressing immune function.

Who It's For

Those wanting immune support alongside tissue repair. See Recovery & Repair for full details.

Who Should Avoid It

Generally well-tolerated. Discuss with provider for specific conditions.

Protocol & Pricing

Pharmacy Price

$80

6mg/mL, 5mL vial (30mg total)

You pay pharmacy price. No markup.

Starting Dose

20 units (1.2mg)

Form

Injectable vial, 5mL

Your pharmacy label will read

ARA290

6 MG/ML (5 ML)

The label shows strength per mL, not the total in the vial.

What that means

  • 6mg/mL means 6mg in every mL.
  • The vial holds 5mL, so 6mg/mL × 5mL = 30mg in the vial.
  • Each 20-unit injection (0.2mL) gives you 1.2mg, about 25 injections per vial.

Dosing Protocol

20 units subcutaneous injection daily. 20 units = 0.2mL × 6mg/mL = 1.2mg per injection.

Beyond Use Date

90 Days from compounding (USP <797>)

A licensed U.S. 503A compounding pharmacy assigns this date and prints it on your vial label. Always follow the label.

ARA-290 certificate of analysis

All 3 ARA-290 samples tested for sterility and endotoxin passed both. Latest sample received by the lab Oct 2, 2026.

Every ARA-290 batch dispensed by a licensed U.S. 503A compounding pharmacy is independently tested by Eagle Analytical Services (FDA-registered, A2LA ISO 17025 accredited). Sterility testing checks that nothing grows in the sample; the USP <85> endotoxin test checks for bacterial toxins that can cause fever. Below is the lab's own report for each of the 3 most recent lots.

How to get ARA-290 prescribed online

ARA-290 is available by prescription after an online medical review and dispensed for human use by a licensed 503A pharmacy. That is what separates it from research-use-only vials sold without a prescription. There is no membership, just a medical review fee per order, and automatic refills are optional.

  1. 1

    Complete a $39 medical review. Answer a short intake about your health history and your goals for ARA-290. The $39 fee is the only charge Rx Peps Direct collects, paid once, not a recurring subscription.

  2. 2

    A licensed provider reviews it. A US-licensed clinician reviews your intake and, if ARA-290 is appropriate for you, writes a patient-specific prescription. The starting dose is typically 20 units (1.2mg).

  3. 3

    The pharmacy compounds and ships it. A licensed 503A compounding pharmacy in Texas compounds ARA-290 and ships it pre-reconstituted by FedEx overnight in a reusable cooled case. Your fill is a 5mL injectable vial at 6mg/mL (30mg total), labeled "ARA290 6 MG/ML (5 ML)", and you pay the pharmacy $80 per vial at wholesale, with no clinic markup, plus a $15 flat FedEx overnight shipping fee charged by the pharmacy.

Rx Peps Direct prescribes ARA-290 in the 28 states plus Washington, DC where its medical team is licensed. Start your $39 medical review or browse the full Immune Optimization range.

Common questions about ARA-290

Is the ARA-290 under Immune Optimization a different product?
No. It is the same product as the ARA-290 listed under Recovery & Repair: the same pharmacy vial (5 mL at 6 mg/mL, 30 mg total), the same price, and the same label. It is listed again under Immune Optimization because ARA-290 is also used in protocols that emphasize immune modulation and inflammation, not only neuropathic pain.
Is there a stronger immune version of ARA-290?
No. The active peptide, concentration, vial size and price are identical; there is no higher-concentration version. What differs is only the protocol goal: immune-focused protocols are typically used for chronic inflammatory presentations (sarcoidosis-style inflammatory tone, autoimmune-spectrum protocols) rather than purely neuropathic indications. Your provider sets the protocol based on the clinical picture, whichever listing you order from.
How is ARA-290 dosed for immune protocols?
Protocols vary by indication. Common subcutaneous schedules deliver 1 to 4 mg per dose, 3 to 7 days per week, for 4 to 12 week courses. A licensed U.S. 503A compounding pharmacy compounds the formulation against Rx Peps Direct prescriptions; your provider sets the protocol on your shipment sheet.
When should I take the ARA-290 immune protocol?
Most patients dose in the morning, but timing is not strict. Consistency over 4 to 8 weeks is more important than time of day. Track inflammatory markers (CRP, ESR) and symptom severity before, during, and after the course so you and your provider can decide whether continuation is warranted.
How is ARA-290 supplied?
Compounded by a licensed U.S. 503A compounding pharmacy under a patient-specific prescription. Ships pre-reconstituted and ready to inject in cold-chain packaging. Every batch is tested by Eagle Analytical Services; the Certificate of Analysis is published on this product page.
