Welcome to the Cognitive & Focus category. This is the place to discuss the science, history, and personal experiences around peptides that are researched for cognition — Semax, Selank, Cerebrolysin, Dihexa, Pinealon, and others in that space.
A few ground rules so this stays useful and stays online. This is an educational community, not a source of medical advice. Please do not post or ask for dosing protocols, dose calculations for a specific person, "what should I take," stack requests, sourcing, vendor links, or reconstitution/injection tutorials. Share experiences as personal anecdote only — never as a recommendation for someone else. When you cite an effect, try to note whether it's from a study, an animal model, or your own impression, because the human evidence here is often thin.
For anything touching your actual health, please talk to a qualified professional who knows your history. Threads that stay curious, cite sources where possible, and stay honest about uncertainty tend to be the ones people come back to. Glad you're here.
