Nootropic peptides are dominated by Russian and Soviet-era research — Semax, Selank and the Khavinson bioregulators — where the published protocols are intranasal or oral, not subcutaneous. That distinction matters: for several compounds here, no subcutaneous study exists in any species, so a microgram injection template is an extrapolation rather than a protocol. Some entries carry specific safety chemistry, such as 9-Me-BC's MAO-A inhibition. The calculators handle the dilution maths; the notes flag where a dose has no source. One more caution specific to this group: several entries are modified forms — acetylated, amidated, or both — sold as improved versions of a parent peptide. For those modified forms the published record is usually empty in every species, and the dosing shown is the parent's, carried across unchanged.
