Selank
Shop SelankAlso called: TP-7, Selank and Semax Research Pair
Selank is a man-made copy of a tiny piece of a protein found in the body. It was made in Russia and is used there as a medicine. In the United States it is not an approved drug. It is sold by research companies as a powder for lab study only, not for people to take.
People are most interested in Selank for its calming effects on the brain. Studies done in Russia suggest it may lower worry and fear, help with low mood and panic feelings, and support focus and memory. It works by sending signals in the brain that help steady mood and stress responses. Because it acts on the nervous system, some people hope it could be a gentler option than older calming medicines.
Here is the honest truth: most of the human research comes from Russia, and big, careful studies from other countries are missing. No one fully knows the right amounts, long-term safety, or all the side effects. In the US it is not approved by the FDA for any use. Products sold online may be impure, mislabeled, or unsafe. Anyone thinking about it should talk to a real doctor first.
Regulatory status
Selank is an approved medicine in Russia for generalized anxiety and stress-related disorders; it is not approved by the US FDA or the EMA. It is not on the FDA's Section 503A Bulks List, remains an unapproved new drug under the FD&C Act, and cannot lawfully be compounded by traditional 503A pharmacies in the US.

mg vs mcg: one milligram (mg) equals 1,000 micrograms (mcg) — multiply by 1,000 going from mg to mcg, divide by 1,000 going from mcg to mg. Mixing the two up is a thousand-fold dosing error: 1 mg taken instead of 1 mcg is a 1,000× overdose; 1 mcg instead of 1 mg is a 1,000× underdose. Always double-check the unit label and the decimal place.

Dated, sourced reporting that mentions Selank.
New York Times sorts peptide-therapy hype from evidence across skincare, muscle-building, and longevity
A November 2025 New York Times explainer takes a skeptical consumer lens to the peptide-therapy craze, separating the few uses with reasonable evidence (topical GHK-Cu and Matrixyl-type peptides in skincare) from the largely unproven injectable and "biohacking" market (BPC-157, TB-500, epitalon, semax, selank). Dermatologists frame cosmetic peptides as "sidekicks, not hero ingredients," while endocrinologists warn that growth-hormone-releasing peptides like sermorelin and tesamorelin carry the same long-term risks as HGH — diabetes, certain cancers, and acromegaly. The piece notes that most longevity claims rest on cell-culture or animal data only, and that "research-grade" products have no quality controls.
Tailor Made Compounding LLC
FDA warned Tailor Made Compounding LLC (Nicholasville, KY) after a 2018 inspection found it compounded drug products with bulk substances ineligible for 503A exemptions. The letter explicitly lists the compounded substances: Follistatin, GHRP-2, GHRP-6, AOD 9604, BPC 157, Bremelanotide (PT-141), Cerebrolysin, DSIP, Epitalon, GHK-Cu, Ipamorelin, LL-37, Melanotan II, Selank, Semax, and CJC 1295, among others. The firm was cited for insanitary aseptic processing (adulteration), unapproved new drugs, and misbranding, and removed GHRP-2 and GHRP-6 from its formulary in response.
