I am thinking of doing a cycle of clenbuterol stacked with T3 over the next few weeks for quick fat loss. I'm very educated on both of them (my boyfrind and I are both personal trainers) , however, I do have one very Random concern. I am currently on the depo birth control shot, and I recently read that combing clenbuterol and/or T3 with other medications and antibiotics can sometimes "cancel out" or negatively effect the accuracy of those medications/prescriptions that are being combined with them. My question is...will taking clenbuterol and/or T3 effect my birth control in any way, shape, or form? I can handle the side effects of Clen, but I really cant chance messing with my depo.
