The range reported for Semax is 100 to 300 mcg, one to three times a day. The human studies that name a route gave it as nose drops, not as an injection, and no human study of injected Semax with a stated dose was found. It is not approved in the US or Canada.
US Not approved Canada Not authorized
The range reported for Selank is 200 to 500 mcg once or twice a day. No human dose could be verified: none of the published human study abstracts gives an amount or says clearly how it was given. It is not approved in the US or Canada.
US Not approved Canada Not authorized
The range reported for DSIP is 100 to 300 mcg, daily or a few times a week. Almost every human study gave it into a vein, dosed by body weight, and the later double-blind trials found little benefit for sleep. It is not approved in the US or Canada.
DSIP (delta sleep-inducing peptide) dosageWhat it is5 mg vial
US Not approved Canada Not authorized
There is no established dose of Pinealon. The one published human dose is 100 mcg by mouth twice a day for two weeks, from a small Russian study. No published study injected it in people; reports of 100 to 300 mcg a day for 5 to 10 days are not a label dose. It is not approved in the US or Canada.
US Not approved Canada Not authorized
No published human study gives a dose for Cortagen. The 0.5 to 2 mg a day that people report comes from sellers and users, and the 10 mcg per kg figure matches a rat nerve study. It is not an approved medicine in the US or Canada, so there is no label dose.
