Repair-signaling peptides for tendons, gut, skin and soft tissue — plus the popular stacked blends.
A stomach-derived peptide that signals tissues to heal faster, especially tendons, ligaments, nerves, and the gut lining, by boosting repair factors and protecting against inflammation and stress.
Helps cells move, build new blood vessels, and reduce inflammation so injured tissues (muscles, tendons, wounds) can repair and regenerate more efficiently.
A small copper-carrying peptide that tells cells to rebuild collagen, reduce inflammation, and protect against oxidative damage; particularly useful for skin rejuvenation and wound healing.
A short anti-inflammatory peptide (fragment of alpha-MSH) that reduces gut and skin inflammation while promoting healing; popular for IBD, colitis, or inflammatory skin conditions.
These recovery peptides are frequently stacked together. The community nicknames:
- Wolverine →=BPC-157 + TB-500
- GLOW →=BPC-157 + TB-500 + GHK-Cu
- KLOW →=BPC-157 + TB-500 + GHK-Cu + KPV
Compounds studied for cellular energy, fuel use, insulin sensitivity, and body recomposition.
A mitochondrial signal peptide that helps cells use fuel better and become more insulin sensitive under metabolic stress.
A mitochondria-targeted peptide that reduces oxidative stress inside the cell's powerhouses, protecting them from damage and improving energy production in aging or diseased tissues.
A vital coenzyme that powers mitochondrial energy production and activates sirtuins for repair and longevity; levels drop with age, so boosting it (via precursors like NMN or NR) supports metabolism, DNA repair, and cellular health.
Inhibits an enzyme (NNMT) that slows metabolism, helping the body burn more fat, preserve muscle, and improve insulin sensitivity; often used for body recomposition and metabolic health.
A synthetic compound that mimics some effects of exercise by activating ERR receptors, boosting mitochondrial function, endurance capacity, and fat burning.
Appetite- and blood-sugar-regulating peptides — the GLP-1 class and its newer multi-receptor cousins.
A triple-action peptide that tells the body to eat less, burn more calories through glucagon, and improve blood sugar control.
A dual peptide that mimics GLP-1 and GIP to suppress appetite, slow digestion, and improve insulin sensitivity, helping many lose significant weight and control blood sugar.
An amylin-mimicking peptide that strongly suppresses appetite and slows gastric emptying, working synergistically with GLP-1s to enhance satiety and support sustained weight loss.
Brain-targeted peptides studied for focus, memory, neuroprotection, and calm.
A brain-derived peptide that enhances focus, memory, learning, and stress resilience by supporting BDNF and protecting neurons.
An anxiety-reducing peptide that modulates GABA and the immune system in the brain, helping calm the mind without sedation while supporting focus and mood.
A mixture of brain-derived peptides and neurotrophic factors that support neuron survival, growth, and repair; used for cognitive recovery after stroke, TBI, or neurodegenerative conditions.
A brain-specific peptide that supports neuron protection, cognitive function, memory, and brain health.
Growth hormone itself and the secretagogues/GHRH peptides that prompt your body to release more of its own.
The master growth peptide that tells the body to build muscle, burn fat, repair tissue, and maintain youthful metabolism.
A growth hormone secretagogue that gently stimulates natural GH release with very little hunger or cortisol increase; popular for muscle growth, recovery, and anti-aging.
A short-acting GHRH peptide that amplifies natural GH pulses (especially paired with Ipamorelin) by stimulating release and reducing the somatostatin brake.
A GHRH analog that raises natural GH and IGF-1, specifically helping reduce stubborn visceral fat while preserving muscle.
Peptides studied for immune-system support.
Boosts the immune system by maturing T-cells and enhancing immune response; used to support immunity during illness, infection, or immune weakness.
Peptides studied for circadian rhythm, telomeres, and healthy aging.
A synthetic peptide mimicking a natural pineal compound; helps regulate melatonin, fix circadian rhythm, reduce resting HR, increase HRV, lengthen telomeres, and support longevity.
