For the off-season athlete there is no anabolic steroid more important or beneficial than testosterone. High levels of testosterone will promote significant increases in lean muscle mass and strength. This is assuming that the individual is consuming adequate calories. Compounds like Testosterone Propionate are not magical, you will still need to feed your body enough calories. During an off-season period of growth, this means total caloric intake will need to be slightly above maintenance. This will, unfortunately, promote body fat gain. However, the key to a successful off-season is gaining lean tissue while minimizing body fat gain to the fullest extent possible. By supplementing with Testosterone Propionate you will be able to achieve this more efficiently. High testosterone levels will promote a stronger metabolic rate. This is not a license to eat like there’s no end in sight, but you should be able to make better use of your calories.
Obviously this is quite a difficult issue, doping in general. I don’t think it can ever be eliminated or even significantly reduced. That being said, I still think we should try. In my opinion, we should continue to fight for that very unrealistic dream of “natural athletes”. I’d love to see what humans are really capable of, even though many would rather go back to an era of Blagoevs, Zlatevs, Suleymanoglus etc. And as for today, we should at least not give preferential treatments to anyone. Every time I hear a British/American low tier lifter whine about the “mighty, roided Russians” or shit like that my stomach turns. Like they’re fuckin clean. And people hate on the exceptional Russian lifters calin them out, while praising Xiaojun and Ilya, who are obiously doped af. It ain’t right.
Hormone replacement therapy has been shown to have other beneficial effects. In a study women taking estrogen through HRT showed that the estrogen positively affects the prefrontal cortex by boosting the working memory. This suggests that estrogen may play a key role in certain frontal lobe functions in women.  Women using HRT after menopause have no additional weight gain compared to women who do not use HRT.  Also women who use HRT with an estrogen component show positive effects in their sex life (mainly increasing their sex drive and sexual sensitivity) but the effects are inconsistent across women. These sexual improvements may dissipate after receiving some forms of HRT for extended periods of time.
