A 24-amino-acid mitochondrial-derived peptide (MDP) with cytoprotective, anti-apoptotic, and neuroprotective activity. Encoded within the mitochondrial genome, humanin represents a new class of retrograde signaling molecules.

An oral, non-peptide growth hormone secretagogue that mimics ghrelin at the GHSR-1a receptor — produces sustained GH and IGF-1 elevation without injections. Extensively studied in human trials.

A long-acting analog of insulin-like growth factor 1 with substitutions that reduce IGF-binding-protein affinity, extending half-life and increasing free IGF-1 activity.

The most selective GHRP (growth-hormone-releasing peptide) — amplifies GH pulses via ghrelin/GHSR receptor without meaningful cortisol, prolactin, or aldosterone crosstalk.

A 37-amino-acid human cathelicidin antimicrobial peptide with broad-spectrum activity against bacteria, fungi, and biofilms, plus immunomodulatory and wound-healing properties.

A synthetic analog of α-MSH that binds melanocortin receptors, inducing melanogenesis (tanning) along with libido and appetite-suppression effects. Pre-PT-141 ancestor molecule.

A splice variant of IGF-1 produced locally in damaged muscle tissue, studied for its role in satellite cell activation and skeletal muscle repair.
