Growth Hormone Peptides — GHRH Analogues & Ghrelin Mimetics
Growth-hormone peptides don't supply GH — they prompt the pituitary to release its own, which keeps the natural feedback loop intact. Two receptor families do the prompting, and the entire reason this shelf is bought in pairs is that they work through independent doors: hit both at once and the GH pulse is larger than either produces alone. Knowing which family a vial belongs to is most of the decision.

Two receptor families, dosed together
Every compound here is a secretagogue, and they split cleanly:
- GHRH analogues — Sermorelin, CJC-1295 (No DAC and DAC), Tesamorelin — activate the GHRH receptor on pituitary somatotrophs.
- Ghrelin mimetics (GHRPs) — Ipamorelin, GHRP-2, GHRP-6, Hexarelin — trigger GH release through the separate GHSR-1a receptor.
Reading the CJC-1295 label: DAC vs No DAC
This is the label people get wrong. No DAC keeps a short active window that preserves natural pulsatile release — the pattern most protocols want. DAC (Drug Affinity Complex) binds albumin and stretches the half-life to days, producing a sustained GH elevation that flattens pulsatility. Both are stocked, the names differ by three characters, and they behave very differently — read it twice at checkout.
Choosing a ghrelin mimetic
Ipamorelin is the reference GHRP because it's selective — it raises GH without the cortisol and prolactin bump that GHRP-2 and GHRP-6 carry, and without GHRP-6's strong appetite stimulation. GHRP-2, GHRP-6 and Hexarelin push a larger pulse amplitude at the cost of those extra effects, which is the trade you're making when you pick one over Ipamorelin.
The pre-mixed blends
The Ipamorelin/CJC-1295 blend is the standard dual-mechanism vial — a ghrelin mimetic and a GHRH analogue in fixed ratio, so every draw delivers the synergistic pair. The Ipamorelin/Tesamorelin blend swaps in the full-length, clinically-backed GHRH analogue. Blends fix the ratio for you; singles let you tune it.
Growth Hormone peptides — buying & shipping FAQ
What you need to know before ordering growth hormone vials.
Why are GH peptides bought in pairs?
GHRH analogues and ghrelin mimetics act on two independent pituitary receptors. Dosed together within a few minutes of each other, they produce a GH pulse larger than either alone — genuine synergy, not addition. That's the whole rationale behind the Ipamorelin/CJC-1295 blend and behind pairing singles.
CJC-1295 with DAC or No DAC — which do I want?
No DAC for most protocols: its short active window preserves the natural pulsatile GH release. DAC binds albumin and extends the half-life to days, giving a flat, sustained elevation that blunts pulsatility. They read almost identically on the label but behave very differently, so confirm which one you're ordering.
What makes Ipamorelin the 'clean' GHRP?
Selectivity. Ipamorelin raises GH without meaningfully elevating cortisol or prolactin, and without the appetite spike GHRP-6 causes. GHRP-2, GHRP-6 and Hexarelin push a bigger pulse but carry those extra effects, so Ipamorelin is the default when you want GH release with the fewest confounders.
Where does Tesamorelin fit?
Tesamorelin is the full-length, FDA-approved GHRH analogue — the strongest human evidence in the GHRH group. It's stocked as a single and inside the Ipamorelin/Tesamorelin blend, which pairs it with a ghrelin mimetic for the two-family synergy in one fixed-ratio vial.
