Fact-checking at PeptideProbe is editorial, not clinical.

Hexarelin is a potent ghrelin-receptor agonist discussed in the literature for GH-secretagogue biology and metabolic/cardiovascular hypotheses. Clinic protocols often keep use short because of cortisol/prolactin and waning-response concerns, but the cited literature does not establish the 100 mcg dose or a 4-week cycle.

Hexarelin Dosing by Use Case

Commonly cited protocols vary by what Hexarelin is being used for. The table below summarizes typical ranges reported in clinical practice and published literature.

Stacking Hexarelin

In clinic/vendor protocols, hexarelin is usually presented as a short-course option because of its potency and cortisol/prolactin concerns. If used with another GH-releasing peptide, that pairing is practitioner-derived; the cited review does not establish a stack.

Where these numbers come from

The cited PubMed paper is a diabetes and diabetes-associated heart-disease review that discusses ghrelin/hexarelin biology, GH-secretagogue effects, and metabolic/cardiovascular hypotheses; it is not a human dosing trial for this protocol. The 100 mcg subQ dose, 1-2x/day schedule, 4-week cycling, and desensitization-management language are clinic/vendor convention, not doses derived from that paper or an FDA label. Cortisol/prolactin and waning-response concerns are presented here as safety/practice context rather than source-established dosing rules.

Use with caution

Hexarelin is a potent ghrelin-receptor secretagogue; cortisol/prolactin and waning-response concerns are reasons clinics limit use, but human dosing evidence is thin.

  • Cortisol and prolactin elevation are reported concerns for less-selective GH secretagogues; dose-specific risk at this chart's protocol is not established by the cited review.
  • Short cycles are used in practice because response may wane with continuous use; this chart does not cite a human cycling trial.
  • Reported side effects: water retention, transient blood pressure changes, joint pain.
  • Not FDA-approved.
Do not use if
  • Active or recent malignancy
  • Untreated hyperprolactinemia
  • Cushing's syndrome or other cortisol disorders
  • Pregnancy or breastfeeding

Hexarelin Dosing FAQ

In clinic practice, hexarelin is generally framed as a brief high-potency option rather than a continuous maintenance peptide. This chart does not cite human outcome data showing it is superior to ipamorelin.

This chart uses 4 weeks on followed by a 4-week break as a clinic-convention cycle. The cited review does not establish that duration, and longer continuous cycles are usually avoided because response may wane.
