Ran testosterone propionate for three years with a washout either side. The washout is the part people skip and it is the only reason I trust my own take.

Vivid dreams and mild headache for the first 13 days, then nothing. Textbook for this class, apparently.

Baseline first. Without a baseline the after picture is decoration.

There is a serious question about whether the studied form matches what is sold, and nobody in a thread can answer it.

Cold storage, light protection, and a date on the vial. Boring, and it removes half the variables.

The interesting question is not whether it works but for whom and at what cost.
