An independent intelligence board aggregating credible research, preprints, clinical findings, biohacking experiments, and community discussions on therapeutic peptides, longevity science, and evidence-based anti-aging. Stories are scored for relevance, credibility, novelty, momentum, and practicality so the most important findings surface first.
Someone on a public forum asked for practical help using a mix of two research peptides, Semax and Selank, and wanted advice on injection schedules plus ideas for free cognitive tests to measure any changes. They’re looking for both dosing stories from other people and for objective ways to track things beyond just “I feel sharper.” The post is basically a request for crowd-sourced protocols and testing tips, not a scientific paper. Semax and Selank are short chains of amino acids called peptides — think of them as tiny, simplified pieces of proteins that can affect brain chemistry. They aren’t the same as Ozempic or the weight-loss drugs you’ve heard about; they’re experimental compounds developed in Russia that have been studied for possible effects on attention, memory, anxiety, and mood. Semax is often described as influencing systems involved in memory and brain repair. Selank is usually linked to anxiety and immune-system-related effects. Neither is a widely approved medicine in most countries; they’re generally used in research settings or as unregulated supplements in some places. The post doesn’t report a controlled study. It’s a person asking for other people’s dosing routines and for recommendations on free online cognitive tests to log changes over time. That means the “evidence” to come from answers will be anecdote — stories from individuals, not results from randomized trials. If people share test scores or before-and-after experiences, those could be interesting signals but can’t prove the peptides caused the change. Online cognitive tests like working-memory tasks, reaction-time measures, or simple attention games can show trends for one person, but they’re noisy and sensitive to practice effects (you get better just from repeating the test). Why this matters: people who think their focus, memory, or anxiety could improve with these peptides want ways to measure whether they actually help. For someone who self-experiments, using standardized free tests and keeping a consistent schedule can help separate real changes from placebo or day-to-day mood swings. Clinicians, researchers, and responsible self-trackers care because objective measurement is the only way to tell whether an intervention is worth continuing. Important caveats: dosing advice from internet forums can be unsafe. Peptides like Semax and Selank are not approved medicines in many places, so their quality and purity can vary a lot. Potential risks include unknown side effects, interactions with other drugs, and infection risk from injections if not done sterilely. Pregnant people, those with serious medical conditions, or anyone on prescription psychiatric medications should be especially cautious and consult a doctor. Finally, cognitive tests are imperfect — practice effects, sleep, stress, and caffeine all change scores — so treat self-reported improvements with skepticism. Bottom line: asking for protocols and tests is reasonable for a self-experiment, but rely on careful measurement and medical advice rather than forum dosing tips, and remember any positive stories you see are only anecdote, not proof.
