Semaglutide is a GLP-1 weight loss drug (brand names Wegovy and Ozempic) that helps reduce appetite and control blood sugar. It's FDA-approved and is one of the most prescribed obesity medications worldwide.

Tirzepatide is a dual-action weight loss drug (brand names Zepbound and Mounjaro) that targets two hormone receptors to reduce appetite and improve blood sugar. It's FDA-approved and delivers stronger weight loss than semaglutide.

Retatrutide is an investigational triple-action weight loss peptide that targets three metabolic pathways at once. In clinical trials, it's produced the strongest weight loss results ever seen from a drug — nearly 29% body weight reduction.

BPC-157 is a healing peptide originally derived from a protein found in the human stomach lining. It's best known for potentially speeding up recovery from injuries to muscles, tendons, ligaments, and the gut. It may work by calming inflammation at injury sites, boosting blood flow to damaged tissue, and helping new blood vessels form — all of which support faster healing. It's especially popular for gut health, where it may help repair the stomach lining and protect against ulcers and irritation. BPC-157 may also support wound healing by improving collagen production, and some research suggests it could help with nerve-related pain by reducing inflammation. It's one of the most widely studied and commonly used peptides in the research community.

Oxytocin is the 'bonding hormone' peptide that plays a role in social connection, trust, and emotional well-being. It's naturally released during hugging, childbirth, and breastfeeding.

NAD+ is a critical molecule for cellular energy production and repair that declines with age. Supplementing NAD+ precursors may help improve energy levels, brain function, and slow aspects of aging.
