Hexarelin Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Hexarelin. All information is for educational purposes only.

Quick Answer

Hexarelin is typically administered via subcutaneous injection. Preclinical research suggests effective doses in the range of 1–3 mcg/kg body weight. Due to the rapid desensitization effect, it is often used in pulsed protocols. No human clinical dose-ranging trials have been completed.

Standard Dosage Range

Research dosing range: 100-300 mcg per dose

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Growth Hormone Pulse

200 mcg1-2× daily
Duration

4-6 weeks (cycled)

Administer subcutaneously. Best used in pulses to avoid receptor desensitization. Commonly used before workouts or before bed.

Cardioprotection (Experimental)

100-200 mcg1× daily
Duration

4 weeks

Based on animal models. Subcutaneous injection. Further research needed to validate efficacy and safety for this use.

Muscle Recovery Support

150-300 mcg1× daily
Duration

4-6 weeks (cycled)

Subcutaneous injection. Taken post-workout to potentiate GH release and aid recovery. Cycle length dependent on individual tolerance.

Timing & Frequency

Injections are typically administered in the morning or before bed, or pre/post-workout. Due to its short half-life (~70 minutes), effects are transient.

Cycle Guidance

Hexarelin is prone to rapid tachyphylaxis (receptor desensitization), so it is crucial to cycle its use. Common practice uses a 4–6 week cycle followed by a 4-week break or longer. Using lower effective dose throughout the cycle is advised to avoid quick desensitization. Monitor prolactin levels if using higher dosages.

Reconstitution Reference

Common Vial SizeTypically 2 mg per vial
BAC Water Volume1 mL bacteriostatic water for 2 mg/mL concentration
Concentration & DrawAt 2 mg/mL: 200 mcg = 0.1 mL (10 units on a 100-unit insulin syringe)
StorageRefrigerate at 2–8°C after reconstitution. Keep lyophilized powder at room temperature or refrigerated.
StabilityReconstituted solution stable up to 30 days refrigerated. Lyophilized powder stable 12-24 months per manufacturer specifications.

Frequently Asked Questions

What is the optimal hexarelin dosage?
The optimal hexarelin dosage varies based on individual response and goals. A typical range is 100-300 mcg per dose. Start with a lower dose (100-150 mcg) to assess tolerance and response, and increase gradually if needed. Due to desensitization, higher doses may not provide additional benefit and may increase side effects.
How often should I inject hexarelin?
Due to its short half-life and the risk of desensitization, hexarelin is typically administered 1-2 times daily. Avoid frequent, repeated injections. Cycling the peptide is crucial to maintain efficacy and minimize the risk of side effects.
What are the potential side effects of hexarelin?
Common side effects include elevated cortisol and prolactin levels, increased appetite, water retention, and possible gynecomastia if prolactin is significantly elevated. Monitor for these effects and adjust dosage or discontinue use if necessary.
How should I store hexarelin?
Store lyophilized hexarelin powder at room temperature or refrigerated. After reconstitution, store the solution refrigerated at 2-8°C. The reconstituted solution is typically stable for up to 30 days.
Is hexarelin safe for long-term use?
Limited long-term human safety data exists for hexarelin. Cycling the peptide and monitoring for side effects are recommended. Consult with a healthcare professional before using hexarelin, especially if you have any pre-existing medical conditions.
