Protocols for the Next Era of Human Optimization

Do peptides degrade during shipping? For lyophilized compounds the answer depends on transit time and temperature. Here is the vacuum-sealed freeze-drying science and how to read a COA on arrival.

LL-37 antimicrobial peptide research covers two distinct mechanisms: direct membrane disruption of bacterial cells and modulation of the innate immune response. Here is what the cathelicidin data shows.

Kisspeptin-10 HPG axis regulation research reveals a master switch for testosterone production that operates upstream of GnRH. Here is how kisspeptin controls the luteinizing hormone surge and what it means for HCG alternatives.

The Melanotan 2 melanogenesis pathway activates MC1R to drive melanin production without UV exposure. Here is how the alpha-MSH analogue stimulates melanocytes and what the dosage curve research shows.

Follistatin 344 as a myostatin inhibitor blocks the TGF-beta pathway that caps muscle growth. Here is the mechanism, the difference from Follistatin 315, and what skeletal muscle research models have documented.

PT-141 bremelanotide sexual function research centers on melanocortin-4 receptor activation in the hypothalamus. Here is how the neurological arousal pathway differs from vascular mechanisms and what the research timelines show.

The KPV peptide mechanism of action directly inhibits NF-κB signaling in intestinal epithelial cells. Here is how this tripeptide reaches inflamed gut tissue and what the IBD research models show.
