Educational summary. See Sources & research below for the underlying studies.
What it is
›
Hexarelin is the most potent GH releasing peptide, but it desensitizes if overused.
• Best for: a strong GH pulse in short bursts
• Catch: the receptor tires out with frequent use
• Has some heart-tissue research too
How it works
›
It strongly activates the ghrelin receptor for a big GH pulse.
• Drives a large, potent GH release
• Stronger than GHRP-2 or GHRP-6
• Overuse blunts the response over time
Dosing and mixing
›
Reference tiers only. Track the dose you are already taking.
Low
100 mcg, once daily
FOR Gentle use to limit desensitization
BENEFIT Often picked as the lower-frequency tier when desensitization is a concern
Standard
100 mcg, twice daily
FOR Short cycles for recovery
BENEFIT The cadence most often cited for short-cycle use
High
200 mcg, twice daily, short term
FOR Aggressive short cycles
BENEFIT A higher-exposure tier with the highest desensitization risk
Schedule: Short cycles only (a few weeks), then a break to reset.
Beginner ramp: Keep doses and frequency modest to avoid desensitization.
Mixing (reconstitution)
BAC water is bacteriostatic water, the sterile water you mix in.
A 5 mg vial with 2 mL BAC water is a common starting point.

How to take it
›
Inject under the skin, on an empty stomach.
• Cycle it, do not run it continuously
• Empty stomach gives the best pulse
• Refrigerate the mixed vial between doses
What to expect
›
Week 1
Strong GH pulse and deeper sleep.
Weeks 2 to 3
Recovery benefits, but watch for a fading effect.
Weeks 3 to 4
Take a break to reset the receptor.
Keep in mind
More is not better here, desensitization is the main risk.
Side effects
›
Commonly reported
• Flushing
• Water retention
• Possible prolactin rise
See a clinician if
• Numbness or tingling that persists
Storage
›
Keep it cold, before and after mixing.
• Powder: refrigerate
• After mixing: fridge, use within about 4 weeks
• Do not freeze, keep out of light
Common stacks
›
• Hexarelin + CJC-1295: people pair these when researching combined GH pathways in short cycles

Potency studies
One of the strongest GH releasers, but the receptor desensitizes.
Practical note
Potency fades with continuous use as the receptor desensitizes.
