What is Selank?
Russian-developed heptapeptide derivative of tuftsin. Used as a prescription anxiolytic in Russia.
Experts on background and overview · 1 cited mention
"Semax metabolizes quite rapidly and then you need to uh take it twice per day or you do Semax and Selank, for example."
How does Selank work?
GABA-A receptor modulator (anxiolytic), enkephalinase inhibitor (extends endorphin action), BDNF upregulator.
Mechanism note
These mechanisms are presented as research observations and hypotheses from the indexed data, not as confirmation of clinical effect in humans.
Experts on mechanism · 1 cited mention
"Semax and Selank - in the same way that they're both increasing BDNF. Did not know that about Selank. I'm just like - anxiety, I like it."
What is Selank researched for?
Reduces anxiety without sedation; also increases BDNF (cognitive benefit). Tanner says he didn't know about the BDNF angle until this conversation - that makes it a dual-action peptide for mood + cognition.
Experts on uses and effects · 2 cited mentions
"JD described Selank as having anti-depressant-like effects; preliminary research suggests anxiolytic and mood-modulating activity, but Selank is not FDA-approved as an antidepressant."
"sank is going to help with calming okay it's an angolytic um think of it as maybe like the anti anxiety like it was like a Xanax without narcotic."

| Speaker | Source | Timestamp | Protocol | Evidence |
|---|---|---|---|---|
| Will (JD Denham co-host) | Peptide of the Week: PE-22-28, pinealon & Cerebrolysin - Mood,... | 00:33:37 | Stack suggestion: PE-22-28 + Semax in the morning, Pinealon midday, Selank and DSIP at night. | anecdotal |
| The Biohacking Specialist | I Injected the Real World Limitless Peptides to See If They Work | 00:13:57 | The host reported using the following protocol: 300 micrograms intranasally split across morning and early afternoon for 14 days (150 mcg morning, 150 mcg midday), avoiding late evening doses. The protocol involved cycling 2-4 weeks on, 2-4 weeks off. When stacking with Semax, the host dosed Semax first thing in the morning and Selank 15-20 minutes later. | anecdotal |
