From the sources to the app
| What the sources say | What PepLabo does with it |
|---|---|
| Semax is used as nasal drops in Russia [2]. | Nasal spray and topical forms skip the unit math; PepLabo records each use with the time and the amount you enter. |
| No human pharmacokinetic studies were found [1]. | Without a matching half-life, PepLabo draws no level chart unless you enter one yourself. |
| Not approved in the US or the EU, so there is no label there [1]. | PepLabo pre-fills nothing: the calculator has no default amount, and the use period after mixing stays empty until you enter it. |
