Has Selank been tested in clinical trials?

No ClinicalTrials.gov registration listing Selank as an intervention was matched (checked October 1, 2026). This is a gap in matched records, not proof that no study exists. PubMed indexes 3 selected human studies in which participants received Selank, most recently “[Optimization of the treatment of anxiety disorders with selank]” (Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova, 2015). The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.

Is Selank legal to buy?

A research-labelled listing does not establish legal eligibility in every jurisdiction. Product status, purpose, import rules and destination matter. Review the jurisdiction-specific sources in the reference notes; PeptideTech does not provide a worldwide legality determination.

How expensive is Selank?

Current in-stock Selank listings range from $4.50/mg (10mg at Nova Peptide Supply) to $6.72/mg (5mg at Cenexa Labs) across 4 vendors. Package size and vendor change the price per mg, so compare the per-mg column rather than the package total. PeptideTech records each vendor's listed price; it does not set or explain them. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.

Filters hide suppliers; the order is always by price. Testing counts the core test categories printed on each supplier’s newest certificate for this exact product. A count is not a quality rating, and vendor claims such as “8x tested” are not used. Destinations and payment methods are those recorded on each supplier’s profile.

Suppliers hidden by the filters: 5. Suppliers shown: 1. Reset filters

What the filters mean

The core 7 are identity, purity, net content, endotoxin, sterility, heavy metals, multi-vial conformity. Identity counts once whether it is shown by mass spectrometry or by HPLC retention time. Sterility counts for a 14-day USP <71> culture or a rapid PCR sterility test, which are labelled apart. Microbial-limit counts and bioburden are not sterility tests. Multi-vial conformity means two or more vials or bottles from one lot measured on the certificate.

Vendors describe batches as “6x”, “7x” or “8x tested” to mean the number of assays on one batch report, and they count differently. Those labels are not used here; only the categories printed on the certificate count.

A supplier without a product-specific certificate is hidden by any testing filter, and so is a certificate that does not state which package size it covers when the supplier sells several. Certificates are vendor documents read by PeptideTech on Oct 7, 2026; the samples are not independently authenticated.

Ships to and payment method use the destinations and methods each supplier publishes, as recorded on its PeptideTech profile. A supplier whose shipping or payment coverage is not recorded is hidden by that filter rather than assumed to qualify. Confirm both at checkout. In stock only hides offers that were out of stock or stale when last checked.
