It calms down the system when it gets too active
A proper specification includes the test, the method, and the acceptance limit
The pattern is consistent: dosing precision matters more than total volume, and subcutaneous administration outperforms intramuscular for systemic recovery applications
Human studies are very limited
Key properties: Stimulates GH release from the pituitary (not the hypothalamus) Does not significantly raise cortisol or prolactin Short half-life (~2 hours) produces a sharp, pulsatile GH release Does not block somatostatin (the hormone that inhibits GH release) Selective for GH minimal effect on other hormones The selectivity is what makes ipamorelin the preferred GHRP for most protocols
