Sermorelin 5mg — GHRH(1-29) Fragment for Pituitary Function Research

Sermorelin is the amidated 1-29 fragment of human growth hormone-releasing hormone — the shortest sequence that retains full biological activity at the GHRH receptor. Because it acts upstream on the pituitary rather than supplying growth hormone directly, endogenous feedback loops via somatostatin remain intact, which makes it a preferred tool for studying physiological GH pulsatility and pituitary reserve.

Research applications

• Shortest fully active GHRH fragment, ideal for receptor-binding studies.
• Preserves negative feedback regulation of the somatotropic axis.
• Used to assess pituitary somatotroph reserve in research models.
• Supports research into sleep architecture and nocturnal GH pulse patterns.

Storage

Store lyophilized powder at -20°C for up to 24 months. Once reconstituted, keep refrigerated at 2°C to 8°C and use within 14 days. Protect from light at all times.

Reconstitution

Slowly add 2.0 mL of Sterile Bacteriostatic Water along the glass wall of the vial. Allow to rest for 2 minutes, then swirl gently until the solution is completely clear. Do not shake.
