Why Sigma A Peptides exists
How did several interesting experiments acquire one confident reputation? That question keeps bringing me back.
Calm and clarity
Selank gets associated with calm; Semax gets associated with clarity. Those reputations offer a satisfying division of labor. Then the experiments intervene: Selank inhibits an enzyme in human plasma outside the body, Semax changes different growth-factor messages in different rat brain regions, and an injury model introduces a different question again.
The awkward pieces are my favourite. The Selank enzyme experiment gives a possible mechanism a precise form, and the Semax regional measurements resist being collapsed into more BDNF everywhere. Each makes the bigger story harder to tell quickly and more interesting to think about.
Sigma suggests a sum to me. The question behind this site is how much can honestly be added together when the units change from enzymes to symptoms to tissue damage. The grand total still eludes me. There are reasons to be interested, and reasons to distrust the ease with which an interesting mechanism becomes a familiar benefit.
About the sourcebook
Sigma A Peptides is a personal sourcebook about published Selank and Semax research. I am offering an argument about these findings, and no medical advice. The site provides neither appointments nor products; treatment questions need a licensed clinician who can assess the person asking them.
The human studies are limited and geographically concentrated, the animal work asks narrower questions, and long-term safety remains unresolved. Descriptions of calm or clarity from online communities are anecdotal accounts rather than clinical evidence.
There is plenty here to justify further investigation without asking a reader to turn an enzyme assay into a personal experiment. My doubts concern that clinical gap; stronger human comparisons and longer follow-up would help close it. Until then, unfinished sums seem the honest state of affairs.
Corrections
An error in the study population or the direction of a result can change the whole argument. For a passage that needs correction, the contact page gives the editorial address and the information that helps me check it. The reading list gathers the source record.
