Are semax and selank legal?
By this site's national fields, both are not approved, research use only in the US, not licensed in the UK, and not approved in Australia or Canada. Semax is approved in Russia and Ukraine for stroke and thinking problems. Selank is approved in Russia for easing anxiety. Being unapproved in the four countries this site tracks is not the same as banned. In July 2026 a US advisory panel voted to recommend Semax for compounding, against FDA scientists. That vote is advice only. Sub-national detail is not in this dataset.

Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.
Part of further names and published absences. Leftover harvested questions after the first two absence sets: more brand versus molecule names, side effects the citations did not count, compounding formulas this catalogue does not hold, national FDA and Australia fields, trial windows rather than an onset clock, named combinations with no interaction table, and oral routes that have not been studied.
