Side-effect

"Gynecomastia is estimated to affect anywhere from 30 to 70 per cent of males at some stage of their lives. And "gyne" or "gyno", as it's commonly known, is not only an unwelcome (and ironic) side-effect of anabolic-androgenic - that is, muscle-building and masculinising - steroids: it can also be caused by other hormonal disruptors such as alcohol, cigarettes, cannabis, obesity, puberty (usually temporarily) and old age. But [Tom] Powell says his gyno was "99 percent" likely due to steroids. […] The new generation of lifters are disparaged as “SARM goblins” for their embrace of the new generation of IPEDs called Selective Androgen Receptor Modulators, which supposedly provide most of the benefits of steroids and fewer of the side-effects, and can be bought online on sites like eBay and Depop."

"Furthermore, we are on the look-out for pre-conditions for good therapy - so as to prevent the unintended bad therapy: but our efforts are duly side-effected by lack of control over such preconditions."
