carefull though... letro will kill your sexdrive without you even noticing it, no matter how much test/androgens you're using.
2 months later your wife will ask if 'something's wrong' and point out that you two havnt had sex in 6 weeks, and you'll be sitting there thinking 'wow... really??!!'.
it'll kill gyno pretty effectively though... but for 'regular' use, I'd rather use arimidex a few days a week (long half life) or aromasin.
adex is about 1/2 as effective in men as it is in women, and it's harher on cholesterol.
aromasin is much more effective in men, and has the benefit of raising free/unbound testosterone, and it improves cholesterol... but aromasin has a short half-life and you need to take it everyday.
for short term gyno-scare's, 2.5mg/day letro and 20mg nolva for a week or two should be plenty.
