You should have done more than just Nola for post cycle. Shoulda had some cloud and Human Chorionic Gonadotropin (HCG) for that. Without it your natural test production will not come back, or if it does it'll take a very long time. Ca lot of ppl make this mistake and end up on Hormone Replacement Therapy (HRT) for the rest of their life. If you were doing test you should have stayed on and just don't your test right before you left and then as soon as u got back, unless u were gone for 2 weeks or more. Nolvas not for post cycle, it's and estrogen blocker. You need to do a lot more reading and learn, and hope its not too late to get your body to recover. You also sound way too young to be doing gear anyway.
