I was told not to mix the A 50 with the Test 400 that if at all possible I should do seperate cycles the A 50 being about 3-4wks. And then the Test 400 for about 4-6 wks. I plan on geting some Liqua-clombid and Liqua-Dex to try with this stuff to try and keep most of my gains. The only thing that really is a problem is that I fall under randoms. I read that A 50 is a water based oral and has a relative short half-life for the most part. The Test on the other hand has a longer half-life and if it shows up in the pee pee it should in most cases show up as me taking Andro or some type of prohormone. I wold claim I was taking andro any way as a "masking" of the juice so to speak. If any one has more poinions please let me know, thank for the info, I really appreciate it.
