NAD+99.5% Pure
Nicotinamide Adenine Dinucleotide

NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in all living cells. It plays a critical role in cellular metabolism, acting as an electron carrier in cellular respiration and energy production (ATP). NAD+ also serves as a crucial substrate for sirtuins and PARP enzymes, which regulate DNA repair, genomic stability, and cellular longevity pathways. Research focuses on NAD+ depletion as a hallmark of aging, making it a focal point in biological studies seeking to restore mitochondrial function and cellular vitality.

Ipamorelin99.3% Pure
Ipamorelin Acetate

Ipamorelin is a synthetic pentapeptide and a selective agonist of the growth hormone secretagogue receptor (GHSR). It is widely classified as a growth hormone secretagogue (GHS). Unlike older peptides in this class, Ipamorelin selectively stimulates growth hormone release without significantly affecting ACTH, cortisol, or prolactin levels. In animal models, it is researched for its influence on lean muscle development, fat metabolism, bone density, and gastric motility.

Retatrutide99.1% Pure
Retatrutide (GIP/GLP-1/Glucagon Receptor Agonist)

Retatrutide is a synthetic peptide that acts as a triple agonist, targeting the glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon receptors. In metabolic research, Retatrutide is studied for its potent effects on insulin secretion, energy expenditure, lipid regulation, and body weight modulation. Its triple-agonist mechanism is highly researched as it represents the latest generation of metabolic signaling compounds.

IGF-1 LR399.0% Pure
Long R3 Insulin-like Growth Factor-1

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic analog of human IGF-1. It is composed of an 83-amino acid chain, incorporating a substitution of Glu for Arg at position 3, and a 13-amino acid extension peptide at the N-terminus. This structural modification reduces binding to IGF-binding proteins (IGFBPs) by over 1000-fold. Consequently, IGF-1 LR3 displays an significantly increased half-life and potency. Researchers utilize this compound to study cellular hyperplasia, muscle cell differentiation, and biological growth pathways.

Tesamorelin99.4% Pure
Tesamorelin Acetate

Tesamorelin is a synthetic peptide consisting of 44 amino acids with a hexenoyl group attached to its N-terminal tyrosine. It functions as a growth hormone-releasing hormone (GHRH) analog. Research shows it stimulates the synthesis and release of endogenous growth hormone by binding to GHRH receptors in the anterior pituitary. Tesamorelin is highly researched in metabolic science for its capacity to reduce visceral adipose tissue (fat), regulate lipids, and modulate body composition in research models.
