Key facts
Mechanism of action
Russian-developed synthetic heptapeptide derived from tuftsin. Anxiolytic without sedation or dependence; used clinically in Russia for generalized anxiety disorder. Limited Western clinical trials.
Standard dosing
Typical clinical use: 300 mcg intranasal 2-3x daily. Dosing varies by indication and provider protocol; this is reference-only and not a prescribing recommendation. Selank requires a prescription from a licensed clinician.
Regulatory status & pharmacy pathway
Not FDA-approved. FDA limits which peptides a pharmacy may compound; check this page’s dated FDA status notice before assuming a peptide is legally available. Ask which licensed pharmacy fills the prescription and check that pharmacy’s license with your state board of pharmacy.
U.S. telehealth providers prescribing Selank
The most commonly cited U.S. telehealth providers for Selank are Defy Medical, Marek Health, Hone Health, Maximus, and PeterMD —, whose offerings for this peptide we have not verified (see the FDA status notice above). See the full provider directory for complete profiles.
Trade-offs to know
Selank carries the trade-offs common to all compounded peptide therapeutics: not FDA-approved, cash-pay only, no in-network insurance coverage, and pharmacy-quality variation between providers. Choose a prescriber that names its pharmacy, explains its follow-up schedule and states the regulatory status of what it prescribes.
