Tesamorelin — approximately 4.5 to 6.0 Tesamorelin is a 44 amino acid GHRH analog — meaning it mimics the hormone that signals the pituitary to release growth hormone. Its solutions typically land in the 4.5 to 6.0 range. At the higher end of that window it begins approaching a more tolerable distance from tissue pH, which is why

Shouldn’t a 220-pound guy take way more than a 130-pound woman?“ — Totally fair question, because we’ve all been trained to think dosing = body size. And for some things, that’s true.

Semax is linked in research to changes in neurotrophic signaling like BDNF/TrkB, and Selank has published work on immune/cytokine modulation in anxious patients. Those systems don’t require gender dosing by default.
