You're going to have to especially be careful when doing this. Your masculinity is coming from synthetic hormones and I know that you have that under control being as you have been on hormone treatment for 4 years. But keep in mind that for men, estrogen is a very carcinogenic substance and for women testosterone is. Even when keeping everything in check and staying on top of bloodwork, your chemistry and every gene in your body is still female. I say this because this is a harm reduction forum, for the most part, lol.

If I we're approach by someone transitioning female to male, I would say stick to the protocol the Dr's have you on. Testosterone, at any more-than-average level for a female, is still going to be dangerous for you. If you add even more, your risk goes up significantly. That why you constantly will see us being stem with guys who don't use an aromatase inhibitor and seemingly don't care about estrogen related side effects until its too late. These same guys are only concerned about the physical side effects and not the internal ones which are the actual dangerous ones. With you, you're not going to have to worry as much in my opinion.

If you were hellbent on ruining a cycle, I'd say anavar for 6 weeks along with your Dr prescribed testosterone. About 40-50mgs daily. I feel it's going to be your safest bet. No need in any of the typical ancillaries for pct and no need to waste money on hcg, as hcg is more geared towards testicular function.

With all of that said, I would first consult your Dr on the matter. I would assume he's not of the conservative nature and you can probably go to him/her to talk about issues such as this. You're in a situation that we don't often encounter, but i would still say to get bloodwork regularly and check ups often.

What do you think of that proposal?
