Beyond the literature: here's what third-party Certificate-of-Analysis records (Janoshik, BCC, Auxlabs) say about real Selank and Semax batches we've tested. Aggregate, public data — cross-reference against the studies below.
We tested 1316 Selank batches across 599 manufacturers, 99.66% avg purity.
We tested 1424 Semax batches across 653 manufacturers, 99.42% avg purity.
We hold deeper lab coverage on Semax (1424 batches tested). Selank edges ahead on average measured purity (99.66% vs 99.42%) — a narrow gap; weigh it against failed-batch and underdose counts above.
Studies in our corpus that mention both Selank and Semax — the gold-standard direct comparison evidence.
This research highlights the potential of Selank as a therapeutic agent for managing non-motor symptoms, specifically anxiety, in Parkinson's disease, even in the presence of significant neurodegeneration. The fact that its anxiolytic effect persists despit…
The analysis successfully identified multiple instances of various putative cognitive enhancing research peptides within the seized preparations. Specifically, well-known compounds such as Noopept, Semax, and Selank were consistently detected across a signi…
This research provides crucial insights into the neurobiological mechanisms underlying the known anxiolytic and nootropic effects of Selank and Semax. Understanding how these peptides modulate specific brain networks could pave the way for more targeted the…
