Hexarelin Reconstitution Calculator & Guide
Examorelin / GH Secretagogue
Hexarelin, also known as examorelin, is a synthetic peptidyl growth-hormone secretagogue. Human studies show potent acute GH release and effects on other pituitary-adrenal hormones, but these findings do not establish long-term performance, recovery, or anti-aging benefits.
Evidence Snapshot
Hexarelin research at a glance
Standardized regulatory and evidence context so research compounds, investigational drugs, and approved medications are not treated as if they have the same level of human evidence.
Regulatory status
Not FDA-approvedDevelopment / evidence stage
Early clinical / human pharmacology
Human evidence level
Human pharmacology / early clinicalPrimary mechanism
Potent peptidyl growth-hormone secretagogue acting through the GHS-R pathway.
WADA context
Explicitly prohibited — S2Human intervention evidence
Human evidence consists largely of short endocrine pharmacology and repeated-administration experiments rather than trials proving performance or body-composition benefits.
Human biology evidence
Controlled human studies show strong dose-responsive GH release and effects on prolactin, ACTH, and cortisol in some settings.
Key takeaway
Hexarelin is a potent human GH secretagogue, but its broader endocrine activity and lack of validated long-term therapeutic outcomes distinguish it from approved GH-axis drugs.

Hexarelin Reconstitution Math
Reconstitution math starts with the amount contained in the vial and the liquid volume used in the calculation. Dividing the vial amount by the liquid volume gives the resulting concentration.
Example vial amount
5 mg
| Liquid Volume | Calculation | Concentration |
|---|---|---|
| 1 mL | 5 mg ÷ 1 mL | 5 mg/mL |
| 2 mL | 5 mg ÷ 2 mL | 2.5 mg/mL |
| 3 mL | 5 mg ÷ 3 mL | 1.6667 mg/mL |
This table demonstrates concentration math only. The liquid volumes shown are examples for comparison and are not preparation recommendations.

What is Hexarelin?
Hexarelin is a synthetic hexapeptide growth-hormone secretagogue, also known by the INN examorelin. It acts through the growth-hormone secretagogue receptor rather than the GHRH receptor used by sermorelin or tesamorelin.
Human GH-release studies
Double-blind and route-comparison studies in healthy volunteers found strong, dose-responsive growth-hormone release after hexarelin. Those experiments establish acute endocrine activity, not a validated chronic anabolic or body-composition therapy.
Hexarelin affects more than growth hormone
Human studies have also documented prolactin, ACTH, and cortisol responses in some experimental settings. That broader pituitary-adrenal activity is important context when comparing hexarelin with more selective secretagogues.
Repeated exposure and response attenuation
Short repeated-administration studies found that hexarelin increased 24-hour GH secretion, while subsequent challenge responses could become blunted. This is another reason single-dose GH peaks should not be translated directly into claims about sustained benefit.
Regulatory and anti-doping context
Hexarelin is not represented by BACToBasics as an FDA-approved U.S. therapy. WADA's 2026 Prohibited List specifically names examorelin/hexarelin among prohibited GH-releasing peptides.
Hexarelin reconstitution math
BACToBasics can calculate concentration from user-entered vial mass and liquid volume. It does not recommend a hexarelin dose, schedule, route, or performance protocol.

Hexarelin FAQ
Tap a question to expand only the answer you want to read.
Does Hexarelin increase growth hormone in humans?
Yes. Controlled human studies demonstrate strong acute GH release.
Is Hexarelin the same as GHRP-6?
No. They are related GH-releasing peptides but are distinct molecules with different research histories and endocrine-response profiles.
Can Hexarelin affect cortisol or prolactin?
Yes. Human studies have reported ACTH/cortisol and prolactin responses in some testing conditions.
Is Hexarelin prohibited in sport?
Yes. WADA specifically lists examorelin/hexarelin among prohibited GH-releasing peptides.
