Semax, Selank, Adamax, Adalank, and Dihexa compared: mechanisms, dose ranges, stacking logic, and evidence quality for nootropic researchers.
For research and educational purposes only. Not medical advice. The nootropic peptide space has a naming problem. The same compound gets sold under half a dozen different labels depending on the vendor. Modified versions of parent peptides carry brand names that do not tell you what is actually in the vial. Some vendors use " Adamax " to mean one thing and other vendors use it to mean something structurally different. And behind all of it is a set of actual amino acid sequences, molecular weights, and mechanisms that determine what a compound does in biological systems. This post decodes all of it. We are mapping every major nootropic peptide in the 2026 research community to its underlying sequence, its molecular weight, its mechanism, and the modifications that create the different versions you see on vendor pages. At the end we have included a complete reference table you can use to verify what you are actually buying. If you have ever wondered what the difference between Semax and N-Acetyl Semax Amidate actually is at the molecular level, or why Adamax is not the same thing as a Semax- Selank blend even though some vendors market it that way, or what Dihexa 's sequence actually looks like relative to its mechanism, this is the post that answers those questions definitively. Why Peptide Naming Conventions Matter More Than Most People Realize Before getting into the individual compounds, the naming problem deserves direct treatment because it has real consequences for sourcing and COA verification. Research peptides are named inconsistently across the market for several reasons. Some names are generic compound identifiers. Some are brand names created by vendors or the original research labs. Some names refer to modification states of the same underlying sequence. And some names have been repurposed by different vendors to mean different things entirely. The only way to know definitively what a compound is at the molecular level is the mass spectrometry peak on a …
