Not talking about steroids — talking about legitimate testosterone optimization through lifestyle and supplements: zinc, vitamin D, ashwagandha, tongkat ali, fadogia agrestis. These can genuinely improve natural testosterone levels in deficient men. The honest answer on size: testosterone levels don't affect adult penile size. Development is determined during puberty. In adults, optimized testosterone improves libido, energy, erection quality, and body composition. It does not change penile anatomy. Worth pursuing for overall health and sexual function — not for size.
