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 | The reported safety profile of Bromantane in Russian clinical trials is generally favourable, with adverse events in placebo-controlled studies often at rates comparable to placebo. The most commonly documented side effects include mild gastrointestinal… | 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 | 322.25 g/mol | ~793.9 g/mol (theoretical: Selank ~751.9 g/mol + N-terminal acetyl, ~+42).

Bromantane is a nootropics that bromantane's mechanism of action is genuinely unusual among cognition-improving and energy-supporting compounds, combining monoaminergic modulation with neurosteroidogenesis in a…. 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, Bromantane or N-Acetyl-Selank? Bromantane 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. ### Which is cheaper, Bromantane or N-Acetyl-Selank? Lowest listed price on BodyHackGuide: Bromantane from $74.99, N-Acetyl-Selank from $79.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack Bromantane and N-Acetyl-Selank? Stacking depends on mechanism overlap, safety profile, and goals. Bromantane and N-Acetyl-Selank should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
