A good introduction to growth hormone peptides because it does not spike cortisol. Timing matters -- most researchers dose before bed.

How It Works
Ipamorelin stimulates the pituitary to release growth hormone in a pulse-like fashion, without meaningfully affecting cortisol or prolactin -- unlike older secretagogues.

- Pulsatile GH release
