hey i have been working out for over 3 years now. i just got on a cycle of M-Drol 4 days ago. i have experience with other phs. i have never come to the situation of stretch marks on the back side of my upper arm right by the arm pit and on the front side of my bicep. several of my frineds recommended coco butter. something tells me its the M-Drol doin it...but how, i just started it 4 days ago i am 6 ft 175ish lbs maybe some more now with very low body fat. i was org 180 (when i just came off a cycle of spawn) and had no stretch marks...y would i get them now when i weigh less????
