I maintained decent bodyweight for quite a few years on hrt doses and nothing else (legit hrt). but my bf was higher.. up around 14% probably at 230-240.
higher test doses, in my experience, equal greater fullness, drive, and strength.
I'd prefer to run 1g of test over 250mg test and 750 'other shit', or even 500 test and 500 'other shit'.
if you're worried about sides, take a couple mg's of adex per week or 12.5 aromasin & 5mg nolva per day, maybe .25mg dutasteride if you're worried about hair.
