Estradiol levels too high

Adipose fat too high

SHBG levels too high

Low vitamin D

Low metabolism which can lead to low steroidogenesis

I'm on TRT for years and I use the gels when not cycling... They are fine for me... Keeps my levels stable and above average... It is annoying to gel up every morning, but I feel 100% better now then I did then... And I've never had any adverse Side effects... I don't know if this helps, but just my experiences... Good luck!
