i had this happen to me too on the cycle that i am on. i did 500mgs of test for ten weeks, but weeks 1-4 i did 20 mgs of d-bol. all the weight i put on from the dbol i kept and didn't gain another pound from the test, but i got a lot of test sides, including great recovery and lots of zits. i decided that once my ten weeks were up on test that i would start d-bol again at 30mgs a day. i've been doing that for a week and i have gained 3 pounds. i think that what might have happened is that i gained a lot of water with d-bol, and then dropped some of it when on test and gained muscle, but i don't know.
