Long post, sorry. Deca-Durabolin (nandrolone decanoate): what actually has human evidence behind it, and what is extrapolation from animals?

Sample size, blinding, and who paid for it. Those three questions kill most of the confidence in most of these threads.

Two weeks is not enough time to attribute anything to a compound unless the effect is dramatic.

The comparison group matters more than the compound when the outcome is something as fuzzy as focus.

Where does the human data stop and the extrapolation start?
