My only tren experience was with homebrew fina. 75mg/day with 500mg/week of test-E.
Aside from the dark urine, I had much more irritability and aggression than with test alone or test and deca. AND, I had unbelievable back acne; large purple cysts that left scars. Oh, and that was the first time I got gyno.
Inhanced libidio but the inability to cum. On tren a number of times I have gone at it for over two hours straight before finally just going limp without getting anywhere.
