The major pharmacologic pathways are… | N-Acetyl-Selank is the N-terminally acetylated analog of Selank, a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the endogenous immunopeptide tuftsin (Thr-Lys-Pro-Arg) with a C-terminal Pro-Gly-Pro tail added to slow enzymatic breakdown.… | | Half-Life | — | Not established for the N-acetyl analog. Parent Selank has a very short plasma half-life (on the order of minutes, as expected for a small peptide) but produces behavioral effects lasting hours, attributed to active fragments and downstream enkephalin/GABA modulation. N-acetylation is claimed to slow N-terminal degradation and extend duration, but this is unquantified in published literature. | | Typical Dose Range | — | 100-900 mcg | | Dosing Frequency | — | Once or twice daily (intranasal); some advanced users split into 2-3 doses | | Administration | — | — | | Side Effects | Tulsi has an excellent safety profile, reflecting thousands of years of food and medicinal use in Indian subcontinent populations. Modern toxicology confirms low toxicity at typical therapeutic doses. Side effects are uncommon and generally mild. Common side… | In short Russian clinical trials, parent Selank was generally well tolerated with no serious adverse effects reported [PMID:18454096]. Reported or plausible effects (largely extrapolated to the analog): mild nasal irritation or congestion from the spray,… | | Molecular Weight | — | ~793.9 g/mol (theoretical: Selank ~751.9 g/mol + N-terminal acetyl, ~+42).

Trend chart unlocks once we have price snapshots from more than one day. ### Tulsi (Holy Basil): potential benefits - No structured benefit list published. ### N-Acetyl-Selank: potential benefits - Anxiolytic (calming) effects - the most-studied action of parent Selank, including a Russian clinical trial in generalized anxiety disorder [PMID:18454096] - Nootropic / cognitive support - reported attention and memory benefits in rodent models, linked to BDNF changes [PMID:31625062] - Stress resilience reported without the sedation, tolerance, or dependence typically seen with benzodiazepines (preclinical framing) [PMID:30255741] - Possible support during withdrawal states (alcohol, opioid) in animal models [PMID:24913576][PMID:36322304] - Claimed longer duration vs. plain Selank from N-terminal acetylation - a community/vendor claim not verified in published data ## Frequently asked ### What's the difference between Tulsi (Holy Basil) and N-Acetyl-Selank? Tulsi (Holy Basil) is a adaptogen that tulsi (ocimum tenuiflorum) operates through diverse mechanisms reflecting its complex phytochemistry — eugenol, ursolic acid, rosmarinic acid, ocimumosides, flavonoids, and others…. N-Acetyl-Selank is a cognitive that n-acetyl-selank is the n-terminally acetylated analog of selank, a synthetic heptapeptide (thr-lys-pro-arg-pro-gly-pro) derived from the endogenous immunopeptide tuftsin…. The two differ in mechanism, half-life (not reported vs Not established for the N-acetyl analog. Parent Selank has a very short plasma half-life (on the order of minutes, as expected for a small peptide) but produces behavioral effects lasting hours, attributed to active fragments and downstream enkephalin/GABA modulation. N-acetylation is claimed to slow N-terminal degradation and extend duration, but this is unquantified in published literature.), and typical dose range. ### Which has the longer half-life, Tulsi (Holy Basil) or N-Acetyl-Selank? Tulsi (Holy Basil) has a half-life of not reported. N-Acetyl-Selank has a half-life of Not established for the N-acetyl analog. Parent Selank has a very short plasma half-life (on the order of minutes, as expected for a small peptide) but produces behavioral effects lasting hours, attributed to active fragments and downstream enkephalin/GABA modulation. N-acetylation is claimed to slow N-terminal degradation and extend duration, but this is unquantified in published literature.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Can you stack Tulsi (Holy Basil) and N-Acetyl-Selank? Stacking depends on mechanism overlap, safety profile, and goals. Tulsi (Holy Basil) and N-Acetyl-Selank should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
