Yah, if you take 100mcg (0.1mg), it'll give you a strong pulse and kickstart your production. Once you get up to a dose of several milligrams, it'll give you chemical castration. There's no need to take more than 100mcg, more will not produce more.
Did you know that GHRP also has a limited ability to produce LH?
Personally, I get a shot of Triptorelin every six months, and I continually use GHRP. I'm not gonna brag about big nuts, but mine never get small.
I'm new here, but I know my stuff. Best regards to all of you.
