Do You Need a Prescription for ARA-290? Is It Legal to Buy Online?
This page answers the legal and prescription question. What ARA-290 is and what its human trials showed is in what is ARA-290, and how it is dosed is in ARA-290 dosage. This is general information, not legal advice.

Treatments mentioned
Yes. ARA-290 meant for a person to inject is a prescription medication in the United States: it has to be prescribed by a physician licensed in your state and compounded by a licensed pharmacy for you by name. ARA-290 sold online without a prescription is a "research use only" product, lawful to sell only because human use is disclaimed. ARA-290, also called cibinetide, is not FDA approved for anything; as of the FDA's 14 May 2026 list it sits in Category 3, "nominated without adequate support," which is a statement about the nomination paperwork, not a safety finding.

Why ARA-290 needs a prescription
The prescription rule
Under section 503(b) of the Federal Food, Drug, and Cosmetic Act, a drug that is not safe to use except under a licensed practitioner's supervision, including because of the method of its use, may be dispensed only on a prescription. ARA-290 is a subcutaneous injection, which meets that test on its face. Dispensing it without a prescription is treated as misbranding, and that rule attaches to the seller.
How a compounded version is lawful
Section 503A exempts a drug "compounded for an identified individual patient based on the receipt of a valid prescription order" by a licensed pharmacist in a state-licensed pharmacy from the new-drug approval requirement. A compounded ARA-290 vial relies on that route. ARA-290 has never been submitted for FDA approval as a drug, so compounding under a prescription is the only lawful way it reaches a patient in the United States. The framework is in are peptides legal in the US.
One molecule, three names
ARA-290 is the developer's code name; the compound came out of Araim Pharmaceuticals. Its international non-proprietary name is cibinetide, which is what the FDA's lists use. Older papers call it helix B surface peptide. All are the same eleven-amino-acid peptide, engineered from one surface of erythropoietin so that it does not raise red cell counts. If you search the FDA's documents, look for cibinetide.

Where ARA-290 stands with the FDA
What Category 3 means
The FDA sorts substances nominated for the 503A bulks list into three interim categories. Category 1 is "under evaluation." Category 2 is "raise significant safety risks." Category 3 is "nominated without adequate support": the nomination did not include enough information for the FDA to evaluate the substance. It is a paperwork category. A nominator can resubmit with adequate support, at which point a substance can move to Category 1.
| FDA list or event | ARA-290 (cibinetide) |
|---|---|
| 503A nominations list, updated 14 May 2026 | Category 3, nominated without adequate support |
| Category 2 (significant safety risks), current as of 22 April 2026 | Not listed |
| Pharmacy Compounding Advisory Committee, 23 and 24 July 2026 | Not on the agenda (that meeting covered BPC-157, KPV, TB-500, MOTS-c, DSIP, Semax and Epithalon) |
| FDA drug approval | Never submitted; not approved |
So the accurate description is: not flagged for a safety concern, not yet evaluated for the bulks list because the nomination was incomplete, and not scheduled for committee review. Category 3 is not a ban and not an endorsement. Compounded medications are not FDA approved.

Why "research" ARA-290 is a different product
| Prescription from a US 503A pharmacy | "Research use only" ARA-290 | |
|---|---|---|
| Who decided you should take it | A physician licensed in your state | Nobody |
| Label | Your name, the drug, the strength, your directions | A product name, a milligram figure, a disclaimer |
| Concentration | Made to the prescription, 2 mg/mL at Pepti | Whatever the sticker says |
| Sterility and endotoxin | Compounded to sterile standards, lot tested | No requirement |
| Preparation | Ready-to-use solution | Often a powder to mix yourself |
| If you react | Message your care team | No one to ask |
The research-use regulation, 21 CFR 201.125, covers material for research "not involving clinical use." A person injecting it is the clinical use the regulation excludes. A second regulation, 21 CFR 201.128, looks at a seller's objective intent, including advertising, so a site selling "research" ARA-290 alongside neuropathy dosing advice is describing a human use. More is in research peptides vs prescription peptides and can you buy peptides without a prescription.

The anti-doping question
ARA-290 is specifically named as a prohibited peptide in the anti-doping literature, and detection methods for it have been published. It does not raise red cell counts, so it is not a blood-doping agent, but that does not make it permitted. A prescription does not create an exemption. If you are tested by any sporting body, check the current prohibited list for your sport before starting anything and tell your physician.

What a lawful prescription looks like
| Requirement | What to check |
|---|---|
| A physician licensed in your state | The prescriber is named and appears on your state medical board's license search |
| A prescription written for you | Your name, the strength and your directions on the vial label |
| A licensed pharmacy | A named, state-licensed pharmacy licensed or registered to ship to your state |
| Published testing | Certificates naming the lab, lot, method and date, with sterility and endotoxin |
A review should also cover what is behind your symptoms. Small-fiber neuropathy has testable causes, such as B12 deficiency, thyroid disease and poorly controlled glucose, and anyone on insulin or other glucose-lowering medication should tell their physician because one ARA-290 trial reported changes in hemoglobin A1c. Bloodwork is not required for any Pepti treatment. If your physician wants labs for your care, they'll ask through your account.

What the evidence shows, honestly
ARA-290 has more human data than most compounded peptides, and it is still limited. Randomized, placebo-controlled phase 2 trials in sarcoidosis-associated small-fiber neuropathy (Molecular Medicine 2012 and 2013, and a 64-person dose-ranging trial in Investigative Ophthalmology and Visual Science in 2017) and in type 2 diabetes with painful neuropathy (Molecular Medicine 2015) reported improved neuropathy symptom questionnaires and increased corneal nerve fiber measures after four weeks. The trials were small, short and run by the developer. Pain-intensity scores did not clearly separate from placebo, and in the 2017 trial only the middle dose beat placebo on the primary endpoint. A 2020 open-label study in diabetic macular edema found no improvement. No phase 3 trial exists. More is in ARA-290 benefits and ARA-290 side effects.

How to get ARA-290 prescribed through Pepti
- Complete the free online assessment: your symptoms, history, medications and allergies.
- A physician licensed in your state reviews it, usually within 24 hours, and may ask questions or decline if ARA-290 is not the right fit.
- If it is appropriate, a PCAB-accredited, FDA-registered US 503A compounding pharmacy prepares it. Lot results are at lab results.
- It ships refrigerated with ice packs as a ready-to-use multi-dose solution, with sterile syringes, alcohol prep pads and your directions printed on the vial.
- Refills every 28 days, one vial per fill, with your care team reachable in between.
ARA-290 is a vial and syringe only; there is no pen. Pepti is cash-pay, does not bill insurance, and prescribes in most US states, not currently in Oklahoma. For comparisons, see KPV vs ARA-290 and thymosin alpha-1 vs ARA-290.

Common questions
Do You Need a Prescription for ARA-290? Is It Legal to Buy Online?, answered.
Yes, for an injection meant for a person. It must be prescribed by a licensed prescriber and compounded by a licensed pharmacy. ARA-290 sold without a prescription is labeled research use only.
Yes, through a telehealth provider where a physician licensed in your state writes the prescription and a licensed pharmacy fills it. Selling a research vial is lawful only because human use is disclaimed.
