Sermorelin is the better choice when someone is in the early stages of GH decline, with very few or minor symptoms
Homogenates were centrifuged at 800 g for 10 min at 4 C, and the supernatant was sonicated on ice for 20 s before protein quantification (BCA protein assay, Pierce, Rockford, IL, USA)
It is a useful reminder that stimulating endogenous GH is not automatically equivalent to, or stronger than, giving GH directly and that the peptides documented effect sizes are modest even in the population where it was best studied
Your bodys natural GHK-Cu levels drop by more than 60% between early adulthood and age 60, precisely when most people start noticing the visible signs of aging
Reconstituting a 50mg vial with 5mL produces 10mg/mL, where a 2mg dose corresponds to 0.2mL
