I have used, at this point, countless batches of GP adex and I can tell you that this a top quality product, In fact, I just used it for my most recent contest prep this year and it worked great,
Heres something you can understand. Adex will do little for you, if prolactin or proges is effecting you from the deca. which it sounds could have been thr problem, you would have needed to take something like caber at .5mg 2x wk along with your adex. If you are sensitive, you could opt to leave deca or tren out of yout cycle and not have to worry about this issue. Maybe test and EQ which can both be controlled with GP adex
