Buy Selank for Research: 2 Vendors Compared (Prices, COAs)

Checked, not rated · Updated 3 October 2026

Selank is not approved by FDA for human use, and it is sold in the US labelled for research use only. 2 of the 3 vendors I check sell it online (Next Level Pharm and BioEdge Research Labs), from $30.99 for a 10 mg vial as of 3 October 2026.

BioEdge Research Labs' product is a different form (N-acetyl Selank amidate 10 mg vial), with a different mass, so check that its COA names that form.

The table compares vendors on FDA record, testing lab, batch COAs and price. Before buying from anyone, run my vendor checklist.

Selank vendors compared

The checklist results come from my review of each vendor and cover the whole store. A vendor can publish COAs for some products and not others. The featured vendor is pinned first; the order is not a ranking.

What a Selank COA should show

A certificate of analysis (COA) is the lab report for one batch. For Selank, check these:

  • Identity by mass spectrometry, with the expected and the measured mass side by side. For Selank, expect about 751.9 Da (C33H57N11O9); the sequence is 7 amino acids, TKPRPGP.
  • Purity by HPLC for this batch, shown as a chromatogram as well as a percentage.
  • A lot number that matches your vial or pack, the test date and the lab's name, so you can confirm the certificate on the lab's own site.

A purity figure does not cover sterility or bacterial endotoxins; a COA covers those only if it reports separate tests for them. Line by line: how to read a peptide COA.

Red flags when buying Selank

  • No certificate of analysis for the batch you will receive, or one without a lot number or a named lab.
  • Dosing instructions or treatment claims for people on the product page.
  • An FDA warning letter naming the seller. Search fda.gov before you pay.
  • No way to pay with buyer protection, such as a credit card.

Common questions

Where can I buy Selank?

Online, from research vendors that label it for laboratory use only. I list 2 checked vendors: Next Level Pharm and BioEdge Research Labs, from $30.99 for a 10 mg vial as of 3 October 2026. Before you pay, confirm the batch COA on the testing lab's own site.

Is Selank for sale legally?

Selank is sold in the US labelled for laboratory research use only. It is not approved by FDA for human use, and it cannot lawfully be marketed as a supplement or a medicine. This is general information, not legal advice.

Do I need a prescription for Selank?

No US-approved Selank product exists for a doctor to prescribe. Research vendors sell it without a prescription, labelled for laboratory use only. It is used clinically in Russia, which is why some vendors call it an approved medicine. It is not approved in the US.

How much does Selank cost?

On the vendors' own product pages: Next Level Pharm, 10 mg vial, $30.99 (as of 3 October 2026); BioEdge Research Labs, N-acetyl Selank amidate 10 mg vial, $39.00 (as of 3 October 2026). Prices change often, so check the product page before you rely on one.

How do I know if Selank is real?

Only a lab test can tell you. Ask for the certificate of analysis (COA) for your batch, and confirm it on the testing lab's own site. The mass spectrometry result should match the expected mass of Selank, about 751.9 daltons (C33H57N11O9). A vendor's COAs for other products say nothing about this one, so check that the certificate names Selank and your lot number.

Who sells the best Selank?

I don't rank vendors, so I don't name a best one. Compare what each lets you check: a named testing lab, a COA for your lot that the lab confirms on its own site, and no FDA warning letter. The table shows my checklist result for each vendor. A vendor that passes every check can still ship a bad batch.
