Featured Technical Samples
[Retatrutide] - Triple Agonist Research Peptide
Retatrutide is an investigational "triple-agonist" peptide currently in Phase 3 clinical trials. It is frequently referred to as the "Triple G" drug because it targets three different hormone receptors simultaneously to regulate metabolism and appetite.
Key Facts and Mechanism
Unlike previous generations of metabolic medications, Retatrutide mimics three naturally occurring hormones:
GLP-1 (Glucagon-like peptide-1): Enhances insulin secretion and slows stomach emptying to increase fullness.
GIP (Glucose-dependent insulinotropic polypeptide): Improves insulin sensitivity and helps the body process fats more efficiently.
Glucagon: Increases energy expenditure (calorie burning) and specifically targets the breakdown of fat in the liver.
In recent Phase 2 clinical trials, Retatrutide demonstrated an average weight loss of up to 24.2% over 48 weeks, which is the highest efficacy seen in this class of drugs to date—surpassing both Semaglutide (~15%) and Tirzepatide (~20-22%).

KLOW
KPV, BPC-157, TB-500, GHK-Cu
KLOW is a comprehensive peptide stack designed for synergistic tissue repair and systemic recovery. Often called the "Radiance Recovery Blend," it combines four well-characterized peptides to target inflammation, cellular signaling, and healing across multiple bodily systems.
Key Facts and Mechanism
Unlike single-molecule agonists like Retatrutide, KLOW is a multi-peptide formulation that addresses recovery through four distinct pathways:
BPC-157 (Body Protection Compound): Known for its rapid regenerative effects on soft tissues like tendons, ligaments, and the gastric lining.
TB-500 (Thymosin Beta-4): A synthetic peptide that promotes cell migration and angiogenesis (new blood vessel formation) to speed up systemic muscle and nerve repair.
GHK-Cu (Copper Peptide): Stimulates collagen and elastin production while acting as a potent antioxidant for skin and hair rejuvenation.
KPV (Lysine-Proline-Valine): An anti-inflammatory tripeptide that modulates the immune response and supports gut integrity.
Each listing contains HPLC/MS PDFs and storage instructions; compliance info is prominent.
Epithalon
Epithalon (also known as Epitalon) is a synthetic tetrapeptide modeled after a naturally occurring substance produced in the pineal gland. It is widely recognized as "The Longevity Peptide" due to its unique ability to influence the aging process at a foundational genetic level.
Key Facts and Mechanism
Epithalon functions as a geroprotector by modulating several pathways that typically decline with age:
Telomerase Activation: Its primary mechanism is the stimulation of the enzyme telomerase, which repairs and lengthens telomeres—the protective caps at the ends of chromosomes.
Melatonin Regulation: It acts on the pineal gland to restore youthful levels of melatonin secretion, helping to re-entrain disrupted circadian rhythms.
Gene Expression: Epithalon can bind specifically to histones and promoter regions of DNA to epigenetically regulate protein synthesis and restore youthful gene expression patterns.
Oxidative Defense: It enhances the activity of key antioxidant enzymes, such as superoxide dismutase (SOD) and glutathione peroxidase, to combat systemic oxidative stress.
