I know advice from new guys to the forums is frowned upon and although I dont claim to have near the practical experience as the veteran members here I am a PhD Biochemist and organic chemist in this general area so I know quite a bit of the theory. But as an athlete I have only undergone self prescribed steroid therapy twice.
These guys are all exactly right, but I do want to point one thing out. In these days of rip off artists, scammers and dismal pricing of these products you want them to be used maximally. Letrozole (femara) is probably the most effective tool we have today for combating steroid induced feminization. I respect all of your experience as I'm sure the process of obtaining it has been trying with lots of hard work and trial and error. I don't want to give advice on the administration of drugs, I am not a medical doctor so I do not write prescriptions. The point I want to make is that letrozole has been shown to be extraordinally powerfull at combatting aromatization of andro parent structure steroids at astronomically small doses. It is so powerfull so it has been shown to be effective in the area of 1 microgram per pound of bodyweight per day. When I self medicated with testosterone, boldenone and oxymethelone (all being self-prepared so I was confident it was genuine material) I took 200 micrograms of letrozole per day, I weigh 165 pounds. Once every couple of weeks I would draw and take the sample down the hall to a friend to give me a test/est and the balance favoured test greatly throughout the cycle, incredible.
Once again, listen to the soldiers who have fought the battles, I just wanted to help you get your moneys worth of expensive products. Like all these guys have said you will also need pct at those dosages. Letrozole is best used everyday of your cycle. As for the guy talking about tamoxifen, I don't know much about nolva but I think it could be stacked with letrozole as one is an antagonist the other a suicidal inhibitor. Basically one blocks the receptor binding site, the other deactivates the enzyme permanantly. Does anyone know if this theory is correct, I'm not 100% sure about tamoxifens mode of action.
Thanks guys, this was not by any means a know it all newbie posting disrespecting the experience of the veterans. I just thought it was an important point. As well all know drugs like these can be counter intuitive so you need to take the advice of the guys who have used them in every context.
