Retatrutide is the most powerful weight loss compound currently in clinical research — Phase 2 trials documented an average 24% body weight reduction over 48 weeks, surpassing every other compound in its class. Currently in Phase 3 trials by Eli Lilly; not yet FDA approved.
Triple AgonistVisceral FatMetabolic RateAppetiteGLP-1 Class
Tesamorelin stimulates the body to release growth hormone naturally, and has shown meaningful reductions in visceral (belly) fat in clinical studies. FDA-approved as Egrifta for HIV-associated fat redistribution; widely studied in body composition research.
Tesamorelin binds GHRH receptors in the pituitary, stimulating pulsatile GH secretion. Unlike exogenous GH, it preserves the natural feedback loop, reducing risk of shutdown.
AOD-9604 is a fragment of human growth hormone studied specifically for fat metabolism — it targets lipolysis without the blood sugar or IGF-1 effects of full HGH. Reached Phase 2 human trials for obesity research.
AOD-9604 stimulates lipolysis and inhibits lipogenesis by mimicking the way natural HGH regulates fat metabolism. It has no effect on IGF-1 levels or blood glucose.
MOTS-c is a peptide produced by your own mitochondria that research shows improves insulin sensitivity, boosts metabolic rate, and has extended lifespan in animal models.
MOTS-c targets the AMPK pathway and regulates glucose metabolism in skeletal muscle. It improves insulin sensitivity and has been demonstrated to reverse age-related metabolic dysfunction in preclinical models.
CJC-1295 and Ipamorelin work together to produce stronger, cleaner growth hormone pulses than either compound alone — without spiking cortisol or prolactin.
BPC-157 has shown remarkable healing effects on muscles, tendons, ligaments, and gut tissue across study after study — making it one of the most researched recovery compounds in the space. Over 100 preclinical studies with consistent results.
BPC-157 promotes angiogenesis, upregulates growth factors, and modulates nitric oxide pathways. It has demonstrated ability to heal tendons, ligaments, bones, and gut tissue in animal models.
TB-500 is a fragment of a protein your body produces naturally for healing — research shows it supports new blood vessel formation, reduces inflammation, and accelerates repair of slow-healing injuries.
TB-500 promotes actin polymerization and upregulation of Tβ4, which regulates cell migration, proliferation, and survival. It reduces inflammation and promotes healing through multiple pathways including VEGF upregulation.
BPC-157 and TB-500 together address injury recovery from two angles — local tissue repair and systemic anti-inflammatory support — making this one of the most studied healing combinations available.
BPC-157 initiates local repair via angiogenesis and growth factor upregulation. TB-500 promotes cell migration and systemic anti-inflammatory effects via actin regulation. Together they address both local and systemic aspects of injury recovery.

NAD+
Nicotinamide Adenine Dinucleotide · Cellular Energy
NAD+ is a molecule found in every cell that powers energy production and DNA repair — research shows levels drop ~50% between ages 40 and 60. Injectable forms have been studied for faster restoration than oral supplements.
NAD+ is a critical coenzyme in oxidative phosphorylation, DNA repair via PARP enzymes, and sirtuin activation (SIRT1–7). Declining NAD+ with age is linked to metabolic dysfunction, neurodegeneration, and reduced cellular repair capacity.
