So the general idea about shbg is that its just some shitty thing that steals your test. While this is partially true, we have ranges on ourlabs for a reason. Yes obviously you don't want high shbg but you definitely don't want very low shbg either. Shbg is responsible for transporting test and stuff around the body. And it controls how fast it's released and how much is released. Now if you don't have any shbg you inject let's say test c, it's supposed to last a little and be steady but without enough shbg your hormones swing rapidly and there's nothing to transport the test. So that test c is out of your body like you just took test prop. And this will cause estrogen rebound in between injections if your doing it 2x a week. And a whole ton of other side effects including insulin resistance,type 2 diabetes, metabolic syndrome, hypothyroidism and others. This gets overlooked SO much and a lot of people can't figure out what's going on. And it's sad cuz even a lot of doctors don't know this so ehow. And if you don't believe me just do your own research. And just remember that basically any anabolic compound lowers shbg. A few things to take to raise it are clomid or progesterone I remember off the top of my head.
