Fellow gym bro here but more of a mountain athlete. I’ve been considering this for a long time. I think the possibke long term side effects outweigh the possible benefits. If you could get a doctor to work with you then I’d say go for it but you can permanently Fuck your natural hormone production if you don’t know what you’re doing and there’s a reason you have to go to school for like a decade to be a doctor. You’d be playing around with some serious shit, could create decades of health issues for yourself if you don’t do it right or if you get bad stuff. It’s not like you have the means to test your testosterone serum at home lol
