Deep dives into peptide science — evidence-graded, honestly reported
Two sister peptides from the same Cold War lab, one calms the emotional floor, the other raises the cognitive ceiling. The mechanistic case for stacking them is architecturally compelling. The clinical evidence for the combination doesn't exist yet.
Selank and Semax are sister heptapeptides engineered with the same glyproline stability tail but from opposite parent molecules, tuftsin (immune) and ACTH (stress). They converge on BDNF through completely different upstream pathways, covering complementary neurochemical territory. This article examines the mechanistic case for combining them, the cofactors that determine whether either signal lands, and where the evidence stops short.
Comprehensive outcome research with safety data and practical protocol references
Detailed compound profiles with mechanisms, safety data, and dosing protocols
A clear-eyed map of the peptides and nutritional adjuncts being used for attention and executive function — what the literature supports, what the FDA has banned, and where the biohacking consensus is running ahead of the data.
An evidence-based exploration of focus and ADHD peptides including Semax, Selank, Noopept, Cerebrolysin and their nutritional adjuncts — with the regulatory, retraction and translational-gap landscape that the biohacking coverage tends to leave out.
A tuftsin-derived heptapeptide that delivers benzodiazepine-level anxiety relief without sedation, dependence, or cognitive fog — while simultaneously boosting immune defence.
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) engineered from the immune peptide tuftsin. It allosterically modulates GABA-A receptors, stabilises endogenous enkephalins, and upregulates BDNF — delivering anxiolysis, cognitive enhancement, and immunomodulation in a single molecule.
