Selank
Also known as: TP-7, Threonyl-lysyl-prolyl-arginyl-prolyl-glycyl-proline, Selank
Selank is a synthetic heptapeptide developed in Russia. It is a modified fragment of the human immune peptide tuftsin, with an added amino acid sequence intended to increase stability. It has been studied as an anxiolytic and nootropic agent, primarily in Russian research settings.
Often sold in blends: Semax / Selank.
How it works
Research suggests Selank may influence the balance of neurotransmitters and interact with GABAergic, serotonergic, and monoaminergic systems. Preclinical and preliminary studies have reported effects on the expression of brain-derived neurotrophic factor and on enzymes that break down enkephalins. The precise mechanism of action in humans is not fully established.

Selank is not approved by the US Food and Drug Administration for any use. It is not a recognized drug in the US pharmacy system and is not available through licensed US compounding pharmacies as an approved therapy. In Russia, a related formulation has been registered and used regionally, but this does not confer US approval. Products sold online as Selank "for research use only" are unregulated and fall outside the licensed pharmacy system.
Selank providers compared
Providers that have passed our rubric review are listed first, then ordered by the total cost of a 3-month protocol. We average every cost to a standard 3-month protocol, which our medical advisors consider the best basis for comparing cost and value, and the headline figure folds in any one-time consult or provider-review fee plus three months of membership. Use the calculator below to adjust the length and see the same total broken out.

We average every cost to a standard 3-month protocol, which our medical advisors consider the best window for comparing cost and value. Monthly plans are multiplied by 3 and 3-month programs are taken as billed; each provider's own sticker price and cadence are shown underneath.
The headline figure is the total 3-month cost: the medication plus any one-time consult or provider-review fee (for example RxPepsDirect's $39) and three months of any membership fee. Where a fee is not published we fold in what is known and flag that other fees may apply.
Per-vial providers are averaged to a 3-month protocol at roughly one vial per month (3 vials), marked "est.", with the per-vial price shown underneath. Actual vial count depends on your dose and protocol.
Prices are gathered from each provider's public pages. The "Verified" date is when we last checked the provider's sticker price; for per-vial providers it is the vial price that was verified, not the averaged 3-month total.
Value check: total cost of therapy
This is the real value comparison. A sticker price hides consult and membership fees, so this adds everything up for a full protocol of Selank and ranks by true total cost. We default to a 3-month protocol, the window our medical advisors consider best for judging value.
Safety notes
Human safety data for Selank are limited and come mostly from small Russian studies. Reported side effects in those studies were generally mild, but long-term safety has not been well characterized in large or independent trials. Because Selank is not part of the licensed pharmacy system in the US, the identity, purity, and content of products sold as Selank are not verified and may vary or be contaminated.
