IGF-1 LR3
Research Compound IGF-1 LR3 (CAS 946870-92-4)
A long-acting recombinant analogue of Insulin-like Growth Factor-1 with an Arg3 substitution and a 13-amino acid N-terminal extension that reduces IGF-binding protein affinity. Research focuses on its IGF-1 receptor binding kinetics, downstream PI3K/Akt and MAPK/ERK pathway activation, and prolonged receptor occupancy in cell-based laboratory models.

Growth Hormone
Ipamorelin
99.0% purity
A selective GHS-R (ghrelin receptor) agonist pentapeptide. Research focuses on its role in stimulating pulsatile growth hormone secretion with high selectivity, minimal cortisol or prolactin interference, and favorable safety profile in laboratory models.
Growth Hormone
Tesamorelin
98.9% purity
A synthetic analogue of growth hormone-releasing hormone (GHRH) with a trans-3-hexenoic acid modification that extends its half-life. Studied for its role in GH axis modulation and visceral adipose tissue research.
Growth Hormone
HGH191AA Somatropin
99.0% purity
A full 191-amino acid chain recombinant somatotropin with identical primary sequence to endogenous pituitary-derived growth hormone. Research focuses on its GH receptor binding kinetics, IGF-1 axis signaling, lipolytic pathway activation, and downstream anabolic signaling via JAK2/STAT5 in cell-based laboratory models.
