Overview
Most metabolic-research compounds in this catalog are incretin-system agonists (GLP-1, GIP, and glucagon-receptor ligands) and related signaling molecules. The published literature studies them for metabolic and body-composition research endpoints. This guide describes how the compound is characterized and what that research covers. It is not usage guidance and makes no claim about outcomes from use.
The 1-29 fragment of GHRH, a long-standing reference compound for GH-axis research.
Evidence at a glance: Includes human-trial data
The cited record for this compound includes human-trial data. Each claim below still states its study type and population, so the scope of that evidence stays explicit.

Researched mechanism
GHRH receptor agonism via the active 1-29 sequence.
Described as a mechanism characterized in the literature, not an effect you should expect from use.
What the published research shows
GH-axis stimulation characterized across decades of research.
Every citation states its study type and population, so preclinical data is never presented as human-efficacy evidence.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| CJC-1295 | Half-life | Sermorelin is shorter-acting than CJC-1295. |
Reconstitution
Concentration math only: adding bacteriostatic water to the vial gives the resulting mg/mL shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 10 mg | 2 mL | 5 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 2 weeks |
Common questions
How does it compare to CJC-1295?+
Both are GHRH analogs; sermorelin has a shorter half-life. See the comparison table.
