Glass — GHK-Cu
GHK-Cu is a naturally occurring copper tripeptide shown to stimulate collagen and glycosaminoglycan synthesis, support dermal remodelling, and upregulate antioxidant defence. Supplied lyophilized as a 100 mg vial.
Restore — Ipamorelin
Ipamorelin is a selective growth-hormone secretagogue (ghrelin receptor agonist) that stimulates pulsatile GH release without meaningful elevation of cortisol or prolactin. Supplied lyophilized, 10 mg per vial.
Heat — PT-141
PT-141 (bremelanotide) is a melanocortin-receptor agonist acting on central arousal pathways rather than vascular targets. Studied for hypoactive sexual desire in both sexes. Supplied lyophilized, 10 mg per vial.
Desire — Kisspeptin-10
Kisspeptin-10 is the endogenous KISS1R ligand and the upstream trigger of the hypothalamic–pituitary–gonadal axis, stimulating GnRH and downstream LH and testosterone release. Supplied lyophilized, 10 mg per vial.
Shred — Retatrutide
Retatrutide is a triple agonist of GLP-1, GIP and glucagon receptors — suppressing appetite while increasing energy expenditure. Phase-2 data showed the largest weight reductions recorded for an incretin therapy. Supplied lyophilized in 10, 15 and 20 mg vials.
Cut — Tirzepatide
Tirzepatide is a dual GLP-1/GIP receptor agonist that slows gastric emptying, improves insulin sensitivity and produces sustained, dose-dependent weight reduction in clinical trials. Supplied lyophilized in 10 and 15 mg vials.
Carve — Tesamorelin
Tesamorelin is a stabilized GHRH analog that restores physiologic growth-hormone pulsatility. Clinically demonstrated to reduce visceral adipose tissue while sparing subcutaneous fat. Supplied lyophilized, 10 mg per vial.
Charge — MOTS-C
MOTS-c is a mitochondrial-derived peptide that regulates metabolic homeostasis through AMPK activation, improving glucose utilization and exercise capacity in preclinical models. Supplied lyophilized, 10 mg per vial.
