Weight Loss
Research-backed weight loss, without the hype.
Metabolic peptides, GH-releasing compounds, glucose-control supplements, and the biomarkers that actually predict body composition change. Evidence-graded by research status, matched to your budget and experience level.

GH-releasing peptides
CJC-1295 + Ipamorelin, AOD-9604 — studied for metabolic effects in animal models
Metabolic supplements
Berberine (AMPK activation), Creatine (lean mass), Omega-3 (inflammation)
Baseline lab testing
HbA1c, ApoB, comprehensive hormone panel — know where you're starting
Ready-made weight loss protocols
Pick your experience level and budget.
Body Composition — Premium Protocol
Full research protocol combining two GH-axis peptides (CJC-1295 + Ipamorelin, AOD-9604) with the NNMT inhibitor 5-Amino-1MQ, comprehensive supplementation, Whoop + Oura for objective load tracking, and a full metabolic + hormone baseline.
Body Composition — Beginner Budget
Supplement foundation for people starting out. Creatine for strength and power, berberine for glucose control, a recovery wearable for objective training load feedback.
Body Composition — Intermediate Stack
Adds the CJC-1295 + Ipamorelin research blend — the most-studied combination for GH secretion research — plus a baseline metabolic panel (HbA1c + ApoB) to track insulin sensitivity.
Peptides studied for body composition
CJC-1295 + Ipamorelin Blend
Combined GHRH and GHRP stack commonly studied together for GH secretion research.
Tesamorelin
GHRH analogue FDA-approved for HIV-associated lipodystrophy. Studied extensively for visceral adipose tissue reduction and metabolic effects.
AOD-9604
Fragment of human growth hormone studied for metabolic effects in animal models.
Hexarelin
Growth hormone releasing peptide (GHRP) studied for GH secretion effects. More potent than GHRP-6 in animal models of GH pulsatility.
