Also known as: Growth Hormone Releasing Peptide-2, KP-102
A synthetic hexapeptide that stimulates pituitary growth hormone secretion by binding ghrelin receptors. Produces strong, pulsatile GH release without significantly raising cortisol. Often stacked with GHRH analogs like CJC-1295 for synergistic effect.
GHRP-6
Also known as: Growth Hormone Releasing Peptide-6
One of the original synthetic growth hormone secretagogues. Similar to GHRP-2 but with a pronounced ghrelin-mimicking appetite-stimulating effect. Favored by those looking to increase caloric intake alongside growth hormone optimization.
Gonadorelin
Also known as: GnRH, Factrel
A synthetic version of the body's natural gonadotropin-releasing hormone (GnRH). Used to stimulate the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural testosterone production.
IGF-1 LR3
Also known as: Insulin-like Growth Factor-1 Long R3, Long R3 IGF-1
A long-acting analog of insulin-like growth factor-1 (IGF-1) with an arginine substitution that reduces binding to IGF-binding proteins, extending its half-life. IGF-1 is the primary downstream mediator of growth hormone's anabolic effects.
Kisspeptin
Also known as: Metastin, KP-10, KP-54
A hypothalamic neuropeptide that acts as the primary regulator of the reproductive endocrine axis, triggering GnRH release and downstream LH/FSH production. Used to evaluate and treat disorders of sexual function and fertility in both men and women.
KPV
Also known as: Lys-Pro-Val, Alpha-MSH tripeptide
A tripeptide fragment derived from the C-terminus of alpha-melanocyte-stimulating hormone (α-MSH). KPV carries the anti-inflammatory properties of α-MSH without its melanogenic effects, making it a targeted tool for gut and systemic inflammation.
Liraglutide
Also known as: Saxenda, Victoza
A GLP-1 receptor agonist administered daily for chronic weight management. FDA-approved as Saxenda for obesity and as Victoza for type 2 diabetes. One of the first GLP-1 medications widely used for weight loss before semaglutide.
LL-37
Also known as: Cathelicidin, hCAP18/LL-37
The only known human cathelicidin antimicrobial peptide, naturally produced by immune cells and epithelial tissues. LL-37 has broad-spectrum antimicrobial activity alongside potent immunomodulatory and wound-healing properties.
Melanotan II
Also known as: MT-2, MT-II
A synthetic melanocortin peptide analog that activates multiple melanocortin receptors. Originally studied for tanning, it also has effects on sexual arousal and appetite regulation.
MK-677
Also known as: Ibutamoren
An oral growth hormone secretagogue that mimics the action of ghrelin, stimulating growth hormone release from the pituitary gland. Unlike injectable peptides, MK-677 is taken orally and has a long half-life.
MOTS-c
Also known as: Mitochondrial Open Reading Frame of the 12S rRNA-c
A mitochondria-derived peptide encoded within the mitochondrial genome. MOTS-c regulates metabolic homeostasis, enhances insulin sensitivity, and has shown promise in extending healthspan in animal studies. Levels naturally decline with age.
NAD+
Also known as: Nicotinamide adenine dinucleotide
A coenzyme found in every living cell, critical for energy metabolism and cellular repair. Levels decline with age, and supplementation is used to support longevity and cognitive function.
Oxytocin
Also known as: OT, Liquid trust, Pitocin
A nonapeptide produced in the hypothalamus and released by the posterior pituitary. Often called the 'bonding hormone,' oxytocin modulates social behavior, sexual arousal, orgasm intensity, and emotional intimacy. Used therapeutically for sexual dysfunction and relationship issues.
P21
Also known as: CNTF analog, Colostrinin fragment
A 21-amino-acid peptide that mimics the action of ciliary neurotrophic factor (CNTF). Studied for neurogenesis, cognitive improvement, and neuroprotection. Shows promise in animal models for enhancing memory consolidation and protecting against neurodegenerative decline.
Pentadeca Arginate
Also known as: PDA, BPC-157 arginate
A stable arginate salt form of a 15-amino-acid sequence related to BPC-157. Developed as a compounding-pharmacy-compatible alternative following FDA regulatory pressure on BPC-157. Offers similar regenerative and anti-inflammatory benefits through overlapping pathways.
PT-141
