Nootropic Peptides
Semax, Selank, Dihexa, Cerebrolysin.
Noopept vs peptide nootropics — same category or different conversation?
Noopept gets lumped in with 'peptide nootropics' because of the name. It's actually a dipeptide-adjacent molecule (GVS-111) that's mostly described as acting on AMPA modulation and BDNF. Subjectively
PDEs and cognition — where do peptides actually fit?
Reading about phosphodiesterase inhibition as a cognition pathway (PDE4, PDE5, PDE9). Most peptides don't directly hit PDEs. So when a peptide improves focus, what's the actual mechanism — is it upstr
BDNF — what actually raises it vs what we hope raises it?
Lot of peptides in this sub get sold with 'raises BDNF' as part of the pitch. Serum BDNF is notoriously noisy and doesn't cleanly reflect central BDNF. Anyone actually tracked it across a peptide run?
Semax dosing — where I landed after 8 months of messing with 300 to 1000 mcg
Posting this because every Semax thread devolves into 'just try it' and nobody commits to a range. I'm 34M, desk job, ADHD-adjacent but no diagnosis, 8 months of intranasal Semax across three reconsti
The Russian stack — Semax + Selank, how are you running it?
Planning to run Semax 600 AM + Selank 600 when anxiety spikes (2-3x/week). Have seen three schools of thought: 1. Same-session dose both peptides back-to-back. Quickest but you have saline drip city.
Tolerance and taper strategies on Semax?
Three weeks in at 600 mcg twice daily and the effect is softening. Do you taper down, cycle off, or just accept it?
Dihexa — is anyone actually using this safely?
Dihexa keeps getting hyped (angiotensin IV analog, allegedly 7 orders of magnitude more potent than BDNF for synaptogenesis on paper, oral bioavailability). I have exactly zero trust in the 'more pote
Selank for anxiety — timing and on-demand use
Running Selank intranasal for situational anxiety (presentations, confrontational calls, flights). 600 mcg 30-45 min before the event. Doesn't feel like a benzo, doesn't feel like nothing. Closest ana
Timing — AM only, or repeated dosing for Semax?
Does repeated dosing (AM + early PM) beat a single larger AM dose? Or am I just manufacturing noise by dosing twice?
Cerebrolysin — 20 day course after a concussion, here's what actually happened
Writing this up six weeks after finishing a standard 20-day Cerebrolysin course. 38M, got clocked in jiu jitsu (accidental knee to temple, brief LOC, textbook mild TBI). ImPACT baseline was available
N-Acetyl Selank vs regular Selank — is the acetylation worth it?
N-Acetyl Selank gets marketed as longer half-life / more stable in solution. I can believe the second part (acetyl capping does protect the N-terminus from aminopeptidases). What I can't tell is wheth
Reconstitution for intranasal Semax/Selank — preservation concerns
What's the accepted practice for intranasal reconstitution? Bacteriostatic water, preservative-free saline, or does it matter? Worried about both degradation and contamination with a spray bottle that
