Cardiovascular
Compounds with research in cardiac protection, blood pressure, vascular function, or circulatory health.
GHRP-6
The original growth hormone releasing peptide, developed in 1984. Researchers studying the GH axis often compare GHRP-6 with its successors as a reference compound.

NAD+
One of the most-studied molecules in longevity science. NAD+ is a coenzyme rather than a peptide, but is widely tracked alongside research peptides for its role in aging, cellular repair, and metabolic function.

Retatrutide
Retatrutide (LY3437943) is a triple hormone receptor agonist developed by Eli Lilly, simultaneously activating the GIP, GLP-1, and glucagon receptors. Phase 2 trials showed approximately 24% mean body weight reduction at 48 weeks, the largest reported for any obesity drug to date.

Semaglutide
Semaglutide has more large-scale human trial data behind it than almost any other peptide women research, and most of what's written about it still ignores the questions women actually ask: what it does to weight at midlife, what the PCOS research shows, and what a fair per-mg price looks like. Here is the evidence, the FDA picture, and the pricing, plainly.

SS-31 (Elamipretide)
SS-31, also known as elamipretide or MTP-131, is a mitochondria-targeted tetrapeptide that homes to the inner mitochondrial membrane and stabilizes cardiolipin. Research spans cardiac aging, hypertensive cardiomyopathy, and skeletal muscle decline.

TB-500
TB-500 is a synthetic peptide fragment studied for tissue repair, wound healing, and cardiac regeneration. Here is what the published evidence looks like.

Tirzepatide
Tirzepatide targets two incretin receptors at once, and in the trial record that has meant the largest weight reductions yet measured in a drug study, results that matter to the women comparing it against semaglutide for midlife metabolic research. Here is what the evidence actually shows, including the heart failure finding that is especially relevant to women.
