Sermorelin

Compound background

Sermorelin (GRF 1‑29) acetate is a bioactive, 29‑amino‑acid fragment of endogenous growth‑hormone‑releasing hormone (GHRH) that retains full affinity for pituitary GHRH receptors, triggering a physiological pulse of growth hormone (GH) and subsequent hepatic IGF‑1 production. In clinical and pre‑clinical studies, intravenous or subcutaneous sermorelin produced dose‑dependent GH peaks comparable to endogenous nocturnal bursts, with rapid clearance (t½ ≈ 10–12 min) that minimizes receptor desensitization. Randomized trials in children with isolated GH deficiency demonstrated improved linear growth velocity, while adult studies documented enhanced fat‑free mass and maintenance of normal cortisol, prolactin, and thyroid axes—underscoring its selectivity for the somatotropic pathway. Because sermorelin acts upstream at the hypothalamic–pituitary level, negative‑feedback mechanisms preserve physiologic GH ceilings, providing a valuable tool for probing GH‑IGF‑1 dynamics, age‑related somatopause, and metabolic modulation in animal and human research models.

Always quality-tested, verified with third party COA’s

At every step, we prioritize quality by conducting rigorous third-party testing on all our products. These tests focus on four key characteristics—identity, purity, sterility, and endotoxicity—ensuring that each batch meets the highest standards for safety and performance, with independent third-party Certificates of Analysis (COAs) to verify our commitment to excellence.

1

Identity Test

Identity testing ensures that the product contains the correct ingredient as labeled, verifying its authenticity and matching it to established reference standards.

2

Purity Test

Purity and concentration testing verifies that the ingredient is present in the correct amount, with a purity of 98% or higher to meet stringent quality standards.

3

Sterility Test

Sterility testing ensures that the product is completely free from bacteria, fungi, and other microorganisms.

4

Endotoxicity

Endotoxicity testing specifically detects and quantifies lipopolysaccharides (LPS), components of bacterial cell walls, to ensure the product is free from harmful endotoxins.
