Adamax Adamax is a modified version of Semax sold as a nootropic research compound. It has no published research of its own, and the suppliers who sell it do not agree on what molecule it actually is. Here is what we could verify. View research notes → Dihexa Dihexa is a synthetic angiotensin IV derivative sold as a nootropic on the research market. The two papers that established how it was supposed to work were retracted in April 2025 for falsified or fabricated data, and the market has largely carried on as though nothing happened. View research notes → NAD+ One of the most-studied molecules in longevity science. NAD+ is a coenzyme rather than a peptide, but is widely tracked alongside research peptides for its role in aging, cellular repair, and metabolic function. View research notes → Pinealon A short synthetic peptide (Glu-Asp-Arg) studied mostly in animal and cell models for neuroprotection, antioxidant activity, and brain aging. Here's what the research actually shows, plus what it tends to cost per mg. View research notes → Selank Selank is a synthetic heptapeptide studied primarily for anxiolytic and cognitive effects. It is approved as a nasal spray in Russia and has one published human clinical trial. Here is what the evidence shows. View research notes → Semax Semax is a synthetic ACTH-derived heptapeptide studied primarily for neuroprotection and cognitive effects. It has regulatory approval in Russia and a growing body of mechanistic research. Here is what the evidence looks like. View research notes → Tesamorelin Tesamorelin is a synthetic GHRH analog FDA-approved as Egrifta for excess visceral fat in people with HIV. Researchers also study it for liver fat reduction, metabolic health, and potential cognitive effects in populations with growth hormone dysregulation. View research notes → VIP (Vasoactive Intestinal Peptide) VIP is a twenty-eight amino acid peptide the body makes on its own, isolated from gut tissue in 1970. Its synthetic form is called aviptadil, and it has more real clinical trial data behind it than most research peptides. Nearly all of that data comes from routes and conditions that have nothing to do with what people buy it for. View research notes →
