Best Place to Buy ARA-290 in 2026

Short answer: Amino Club (Bureau Score 4.8), the Bureau's first choice for ARA-290. Below is why, the three alternatives worth knowing, and what to check before any order. ARA-290 is sold by these stores for laboratory research use only, not for human use. It is also known as cibinetide.

What to know before buying ARA-290

ARA-290 is cibinetide, an 11 amino acid linear peptide (pGlu-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser) modelled on helix B of erythropoietin, also called pyroglutamate helix B surface peptide (pHBSP). It does not stimulate red blood cell production and is studied for tissue protection through the innate repair receptor, including small nerve fiber loss and neuropathic pain.

Cibinetide is an investigational compound with no FDA approval (no product in Drugs@FDA, checked 1 Nov 2026); its developer Araim Pharmaceuticals ran phase 2 trials, including a 64 subject, 28 day phase 2b trial in sarcoidosis related small nerve fiber loss published in 2017. It is not on FDA's compounding safety page.

• What to match on the certificate: Match the identity line to C51H84N16O21, average molecular weight 1257.3 (monoisotopic 1256.60), with the N-terminal pyroglutamate. Look for HPLC purity and mass spec identity on the same lot number as the vial.
• Vial sizes: Research stores mostly sell 10 mg vials, with 16 mg and 50 mg at a few, so compare price on the same size.
• What it costs: 5 stores the Bureau reviews list ARA-290; on 1 November 2026 the in-stock list prices ran from $4.69 per mg (Ion Peptides, 16 mg vial) to $6.00 per mg (Ascension Peptides, 10 mg vial), before any code.
• Storage: Suppliers generally state that a lyophilized peptide keeps best sealed and frozen (around -20 C), and that once reconstituted it should be refrigerated and used within a short window or split into aliquots and frozen, avoiding repeated freeze and thaw.

The alternatives

Each one stocks ARA-290 and has been through the Bureau's vendor review. Listed in the Bureau's own vendor order, not by price.

Side by side

Prices are list prices for single vials, read from each store by the Bureau's Vendor Watch on 1 November 2026, before any code. Prices change daily.

How the Bureau picks

The pick is the vendor at the top of the Bureau's vendor list that stocks ARA-290. Scores come from the scorecard, which weighs lab documentation, consistency, shipping and price, and a vendor cannot buy a score. Before any order, match the lot number on the vial to a certificate from a named third-party lab. More in the vendor scorecard.

Frequently asked questions

Where is the best place to buy ARA-290?

The Bureau pick is Amino Club (Bureau Score 4.8). Batch COA on every product page from an 8-assay panel at an ISO 17025 lab. Alternatives that stock it: Ascension Peptides, NextgenPeps, Limitless Biotech.

Is there a discount code for ARA-290?

Reader deals checked by the Bureau: Amino Club, Code 100: 20% off; Ascension Peptides, Our link: 50% off every order; NextgenPeps, Code PEPTIDEBUREAU: 10% off.

How do I check a ARA-290 vendor before ordering?

Match the batch or lot number on the vial to a certificate from a named third-party lab, check the test date, and look for identity (mass spec) as well as purity (HPLC). The Bureau's scorecard records which vendors do this.

Is ARA-290 FDA approved?

No. Cibinetide (ARA-290) has been through phase 2 trials but has no FDA approval, so it is sold by research vendors for laboratory research use only.

What did the ARA-290 trials show?

In a 2017 phase 2b trial of 64 people with sarcoidosis related small nerve fiber loss, one cibinetide group showed a significant increase in corneal nerve fiber area after 28 days compared with placebo, a surrogate measure of nerve regrowth. It has not been tested in a phase 3 trial.
