I volunteered on a trial study about occlusion training. I have to train 3 times a week with their setup. Before and after every training they will take a biopsy from my quadriceps. The guy asked me if i was on steroids. Obviously that would influence the results so they wouldn’t want that. I’m not on steroids, but i did one cycle 2 years ago. Will this influence their studies? Will they be able to tell that by the muscle biopsy?
