Yes CPA works really well, however you must be aware of the increase in prolactin with the use of CPA which can result in prolactinomas and meningiomas(benign brain tumors) as it's most threatening possible side effect. which makes it unsafe for long term use, i think its use should only be short term if it's your current AA of choice. Bicalutamide is a newer AA derived from Flutamide as a 2nd generation NSAA and it works extremely well, with a higher safety profile and less liver toxicity, safer than spironolactone, CPA, Flutamide etc, and i probably would have never found it if it weren't for
@Ikarus bringing it up a while back 'cuase i didn't even know what NSAA's were. Bicalutamide is the strongest and safest AA so far that I've found.
@itsyaboi the upregulation in T won't matter because it wont be able to bind to its receptors anyway, encase that's what you're worried about, but 2mg E will balance it out so in the case you have to stop Bicalutamide your T will be normal-ish. and you have to use E with Bicalutamide or you'll likely get hot flashes, dizziness, dowdiness and other hormone imbalance symptoms anyway. Bicalutamide usually presents little to no side effects in users who have a female hormone profile, males experience the things i mentioned above if they don't use E while blocking all their T and same goes for other AAs.
