Learn About Peptides.
Peptides are getting a lot of buzz in the fitness world — and for good reason. These small chains of amino acids play real roles in how our bodies heal, build muscle, and manage metabolism.
How Peptides Work — The Simple Science
Peptides are your body's messengers — short chains of amino acids that deliver instructions, telling your body to release growth hormone, repair tissue, regulate appetite, or sleep more deeply. They work because they speak your body's own language: each peptide fits its receptor like a key in a lock, triggering processes your body already knows how to run — it's the same science behind insulin and today's FDA-approved peptide medications. And since our natural peptide production declines as we age, the fundamentals matter more than ever: resistance training, protein-rich meals, and deep sleep all stimulate that same signaling system naturally. The science is real and exciting!

An experimental NNMT inhibitor studied mainly in animals for potentially reducing fat accumulation and improving metabolic function.
Promoted for tendon, ligament, muscle and gastrointestinal healing, although convincing human clinical evidence remains very limited.
Stimulates growth-hormone release and is promoted for recovery, sleep and body composition, but this combination lacks approval and robust clinical evidence.
A naturally occurring copper-binding peptide studied primarily for supporting collagen production, skin remodeling and wound healing.
An investigational GLP-1/GIP/glucagon receptor agonist showing substantial weight-loss and metabolic benefits in clinical trials but not yet an approved treatment.
A mitochondrial-derived peptide investigated for potentially improving energy metabolism, insulin sensitivity and exercise capacity, primarily in early research.
A neuroactive peptide studied for possible neuroprotective, cognitive and attention-related effects, but it is not FDA-approved.
A growth-hormone-releasing hormone analogue that stimulates the pituitary gland to produce growth hormone and may help evaluate or treat selected cases of GH deficiency under medical supervision.
An FDA-approved GHRH analogue that reduces excess visceral abdominal fat specifically in adults with HIV-associated lipodystrophy—not a general weight-loss drug.
Marketed as a combined tissue-repair and injury-recovery protocol, although its effectiveness and safety have not been established in controlled human trials.
A small anti-inflammatory peptide investigated for potentially reducing intestinal and skin inflammation, with evidence currently concentrated in laboratory and animal research.
A mitochondria-targeting peptide designed to stabilize mitochondrial membranes and improve cellular energy production, with benefits still being evaluated for specific diseases.
Delta sleep-inducing peptide has been studied for sleep and stress regulation, but human findings are inconsistent and do not establish a reliable sleep benefit.
A long-acting laboratory analogue of IGF-1 promoted for muscle growth and recovery, but it is unapproved and may carry serious metabolic and tissue-growth risks.
An experimental peptide investigated for possible effects on circadian regulation and cellular aging, without convincing evidence that it extends human lifespan.
Vasoactive intestinal peptide naturally supports smooth-muscle relaxation, blood-vessel dilation and immune regulation and is being investigated therapeutically for pulmonary and inflammatory conditions.
A short experimental peptide promoted for neuroprotection and cognitive support, but reliable human clinical evidence is sparse.
An oral non-peptide growth-hormone secretagogue that raises GH and IGF-1 and may increase lean mass, but it is unapproved and can impair glucose control or cause fluid retention.
FDA-approved as Vyleesi for acquired generalized low sexual desire causing distress in certain premenopausal women—not for men or general sexual-performance enhancement.
An FDA-approved GLP-1 receptor agonist that improves glucose control and, in appropriate patients, supports substantial weight loss and reduces certain cardiovascular risks.
An experimental senolytic peptide designed to remove certain senescent cells and improve tissue function, with evidence currently limited largely to preclinical models.
