Hex
Hexarelin (Examorelin) is a synthetic hexapeptide and the most potent GHRP in terms of raw GH release per dose. It activates the ghrelin receptor (GHS-R1a) with the highest efficacy of the GHRP family but also desensitizes the receptor fastest, requiring shorter cycle lengths (4-8 weeks) compared to Ipamorelin (8-16 weeks). Hexarelin produces significant cortisol and prolactin elevation and moderate appetite stimulation. It also has unique cardioprotective properties independent of GH release, acting directly on cardiac tissue.
Fasted 2+ hours. Bedtime preferred. Do not use longer than 8 weeks continuously (desensitization).
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
Hexarelin activates GHS-R1a with the highest efficacy of any GHRP. Also has direct cardiac effects independent of GH, including cardioprotection via scavenger receptor CD36 binding and activation of protective signaling in cardiomyocytes. Desensitizes GHS-R1a faster than other GHRPs due to strong receptor activation, requiring cycling.
Days 1-7: Strong GH response. Hunger and flushing.
Weeks 2-4: Peak effects.
Weeks 4-8: Desensitization begins. Cycle off.
Each reference below was re-fetched from its PubMed record, and the quoted sentence was confirmed to appear in that abstract and to support the claim it sits under. Follow any of them to read the source.
Evidence boundary from the checked abstract: Accordingly, hexarelin induced a reduction of wedge pressure (P < 0.01).

Evidence scope. This entry supports only the exact statement quoted from the live abstract; it does not independently verify OnePin's displayed dose, route, frequency, formulation, population, or broader mechanism.
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 100-200 mcg; SubQ injection; 1-2 times daily, shorter cycles. No checked live PubMed abstract verified this exact displayed dose, route, and frequency for the same molecule/formulation and relevant population.
Primary safety claim: No primary safety text present in source JSON. No checked live PubMed abstract directly verified this source-JSON safety claim at the displayed formulation, route, and regimen.
Most potent GHRP
Confirmed. Highest GH release per dose. Trade-off is faster desensitization.
Unique among GHRPs. Direct cardiac effects via CD36 scavenger receptor independent of GH. Published human cardiac data.
Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.
Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.
