Dianabol

Short answer



Yes – when someone has a clinically low level of testosterone, replacement can give real health benefits (better energy, mood, muscle mass, bone density, etc.).

But it also carries significant risks: acne, hair loss, prostate changes, increased cardiovascular risk, blood‑clotting problems, and in some cases a rebound suppression of your own hormone production.




So the bottom line is that testosterone should only be used under medical supervision when you have a documented deficiency; it’s not a harmless "boost" that anyone can take for a quick pick‑up.
