Where the catalog organizes peptides by mechanism, these guides organize them by what they’re studied for — the indication or use case. Each area covers the underlying biology, the peptide classes involved, and links to every matching catalog entry.
Incretin and metabolic peptides studied for glycemic control and fat loss.
Regenerative peptides studied for soft-tissue, tendon, and vascular repair.
Nootropic and neurotrophic peptides studied for cognition and recovery.
Regulatory peptides studied for anxiolysis and stress-axis modulation.
Peptides studied for sleep architecture and circadian regulation.
Peptides studied across the aging axis — senescence, NAD+, and resilience.
Secretagogues studied for GH release, IGF-1, and body composition.
The activin/myostatin axis studied to preserve muscle during GLP-1 weight loss.
Peptides studied for skin aging, pigmentation, and hair follicle biology.
Peptides studied across the HPG axis and CNS sexual-response pathways.
Thymic and host-defense peptides studied for immune modulation.
Mitochondria-targeted peptides studied for bioenergetics and cardiolipin.
Short, tissue-specific peptides proposed to regulate gene expression — the Khavinson series.
How hormone sequences are turned into pure, stable, manufacturable synthetic drugs.
Most peptide references sort compounds by chemistry. That’s the right frame if you already know what you’re looking for – but most research questions start from the other end: a biological outcome, and the open question of which signaling systems reach it. These guides are built for that direction of travel.
Each guide starts from the use case – weight loss, tissue repair, cognition – then works down into the receptor systems and peptide classes under study, so the biology explains the grouping rather than the other way around.
Every guide links to each matching catalog entry – sequence, mechanism, key research, and evidence tier – so you can move from indication overview to compound detail in one step, and back.
Where a class is clinically validated, the guide says so; where the evidence is preclinical, it says that too. The standards behind those calls live on the methodology page.
