SHBG is one of the main reasons why guys feel low T even when bloodwork looks fine SHBG is a protein made in the liver that binds testosterone and estrogen in the blood when SHBG is high most of your testosterone is locked and cant do anything only free testosterone actually works in tissues so you can have normal or even high total T and still look soft tired low energy weak jaw bad eye area no androgen edge this is why total testosterone alone means almost nothing without SHBG
High SHBG reduces androgen effect on the face and body less muscle harder to stay lean worse response to gym more neutral npc look lower drive and confidence a lot of guys blame genetics but biochemistry plays a huge role quietly
Things that push SHBG up are undereating very low bodyfat chronic stress bad sleep thyroid issues high estrogen and doing endless cardio with no lifting this is common in guys who diet too hard or live in stress mode all the time
Lower SHBG usually means more free testosterone and stronger androgen signaling better look better gym response but too low SHBG is also not ideal because hormones become unstable so balance matters
The main takeaway is that hormones are not just about how much you have but how much is free and usable SHBG explains why many guys look low androgen without actually being low T on paper
