HCG effects on TSH

HCG and TSH have a similar structure. HCG can act as TSH and increase thyroid hormones. That happened to me. It is more common is very high dosages but might happen in smaller dosages. However I dont think it would increase TSH lab values.
 
I use 200/250 daily and have for 7 month straight now.. I must also add if I use 400iu daily for say 3d I run around like a buzzy bee and then crash. I did this about 9days ago I guess I should of waiting a bit longer or even not pin any HCG for 4/45 days to see results.

What was your hcg dose when you felt like it increased tour thyroid activity?

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
