# Sermorelin / GHRP-2 Blend

> This blend pairs sermorelin, a truncated GHRH(1-29) analog with a long history in growth-hormone research, with GHRP-2, a potent ghrelin-receptor agonist. It represents one of the earliest and most extensively referenced secretagogue combinations, predating newer analogs such as CJC-1295 and ipamorelin. Sermorelin was previously marketed as an approved growth-hormone-deficiency treatment before that product was discontinued, giving it a comparatively long clinical research history; it is currently used as a compounded research peptide. GHRP-2 is studied as a more potent secretagogue than GHRP-6 with somewhat less pronounced appetite stimulation. The combined blend itself has not been evaluated in formal trials, though each component has an extensive individual research record.

- Also known as: Classic GH Blend
- Primary category: GH Blends
- Effectiveness rank: #999 in Growth Hormone Peptides; #999 in GH Releasing Hormones; #4 in GH Blends
- Evidence level: Well studied
- Route: Subcutaneous (Injected subcutaneously, generally 2-3 times daily given the short duration of action of both components, often timed around meals and bedtime.)
- Dose range: 200-500 mcg
- Dose tiers: low 200 mcg; moderate 300 mcg; high 500 mcg
- Half-life: Sermorelin is reported at roughly 10-20 minutes and GHRP-2 at roughly 30-60 minutes; both are short-acting, requiring multiple daily doses to maintain a research protocol.
- Timing: ~30 min before bed, empty stomach
- Cycle: 8-12 weeks on, 4 weeks off (As one of the older secretagogue combinations, cycling recommendations largely mirror those developed for the newer CJC-1295/ipamorelin pairing.)
- Storage: Refrigerate after reconstitution (2-8°C); commonly described as stable for 2-3 weeks.

## Mechanism of action

Sermorelin binds the GHRH receptor, stimulating pulsatile GH release in a pattern intended to mirror endogenous GHRH signaling, with a short duration of action. GHRP-2 acts at the ghrelin receptor (GHS-R1a), producing a robust secretagogue effect with a comparatively moderate impact on appetite, cortisol, and prolactin relative to GHRP-6. Combined, the two pathways are described as producing a strong GH pulse when dosed together.

## Reported benefits

- Stimulates growth-hormone pulse via two distinct pathways
- Long individual research history for both components
- Reported to support sleep quality
- Associated with recovery and lean body composition research interest

## Reported side effects

- Flushing
- Injection site reaction
- Mild appetite increase
- Water retention
- Headache

## Common protocols

- Classic GH Stack
- Sleep Optimization
- Recovery Protocol

## Stacking notes

A predecessor combination to CJC-1295/ipamorelin; some researchers still prefer it for its longer individual track record, though newer analogs are more commonly referenced today.
