Sermorelin

Classic nightly GHRH fragment. Old diagnostic product was Geref.

What it does / how it works

The first 29 amino acids of GHRH. Nightly use aims for a sleep-associated GH pulse and a later IGF-1 rise. Old diagnostic product was Geref.

Class	GHRH(1–29)
Typical vial	5 or 10 mg
Reconstitution	2 mL BAC per 5 mg = 2.5 mg/mL
Storage after mix	2–8°C, use within 28 days

Protocol

Sermorelin FAQ — Australia

Where can I buy Sermorelin in Australia?

ELV8 Labs offers Sermorelin in 10 mg vials, third-party tested at a leading Australian university. For research purposes only.

How does Sermorelin compare to CJC-1295 (No DAC)?

Both are GHRH analogues targeting the same receptor. Sermorelin uses the native human GHRH sequence with a shorter half-life (~10–20 min), while CJC-1295 No DAC has amino acid substitutions extending its half-life to ~30 min. CJC-1295 is more commonly referenced in Australian research for its improved stability.

When should Sermorelin be administered?

Pre-sleep administration (30–60 minutes before bed) is the most commonly referenced timing in published protocols, aligning with the natural nocturnal GH pulse. Fasted administration may also enhance the GH response.

Can Sermorelin be combined with Ipamorelin?

Published clinical research on Sermorelin used longer administration periods (3–6 months) and observed gradual, cumulative effects on GH parameters. The peptide’s physiological mechanism and the time required for downstream GH/IGF-1 changes to manifest in test subjects support longer cycle durations.

Why are Sermorelin cycles longer than other peptides?
