Hexarelin dosage by goal

Grouped by goal. Each protocol shows the amount, how often, cycle and rest as the source states them, with every titration step.

Trial4

Trial: twice daily for 16 weeks

Amount: 1.5 mcg/kg
How often: Twice a day
Route: Subcutaneous injection
Cycle: 16 weeks

Who: 12 healthy elderly adults (Manchester trials)

Note: GH response dropped by week 4 and stayed lower at week 16, then returned to baseline 4 weeks after stopping.

Trial: 2 or 3 shots in one day

Amount: 1.5 mcg/kg
How often: 2 or 3 times over 24 hours
Route: Subcutaneous injection

Who: 6 healthy young men

Note: Two and three shots raised 24-hour GH by the same amount, with no change in prolactin, ACTH or cortisol.

Trial: single IV test dose

Amount: 0.5 to 2 mcg/kg
How often: A single IV dose
Route: Intravenous (IV)

Who: Healthy adult volunteers in 1994 dose studies

Note: Used to measure GH release, not for ongoing use. GH peaked about 30 minutes after the dose, and 2 mcg/kg was close to the maximum response.

Trial: nasal spray in short children

Amount: 60 mcg/kg
How often: 3 times a day
Route: Nasal
Cycle: Up to 8 months

Who: 8 prepubertal short children aged 4 to 11.6 years

Note: Pediatric trial only: a per-kg dose for prepubertal children, not an adult protocol. Nasal absorption is low (about 4.8% vs 77% subcutaneous in a separate adult study), which is why the nasal dose is so much higher per kg.

Other protocols: injected12

Forum convention

Amount: 100 to 200 mcg
How often: 1 to 2 shots a day
Route: Subcutaneous injection
Cycle: 8 to 12 weeks on
Rest: 4 weeks off

Who: Bodybuilding forum protocols compiled in a 2026 peer-reviewed review

Community standard

Amount: 100 to 200 mcg
How often: 2 to 3 times a day, on an empty stomach
Route: Subcutaneous injection
Cycle: 8 to 12 weeks
Rest: 4 to 6 weeks off

Community starting dose

Amount: 100 mcg
How often: Once a day for the first 1 to 2 weeks
Route: Subcutaneous injection
Cycle: First 1 to 2 weeks, then titrate up

Note: Used to check response and side effects before moving up to the standard range.

Self-logged doses

Amount: 100 to 200 mcg
How often: Per logged entry; median bucket 100 to 200 mcg (84 logs), next 200 to 400 mcg (59)
Route: Subcutaneous injection

Who: PeptIQ app users, 24 community reports

Beginner

Amount: 100 mcg
How often: 1 to 2 times a day
Route: Subcutaneous injection
Cycle: 4 to 6 weeks on
Rest: 2 to 4 weeks off before restarting

Timing: Fasted: before breakfast and/or before bed, 2 to 3 hours after the last meal.

Intermediate

Amount: 150 to 200 mcg
How often: Twice a day, before breakfast and before bed
Route: Subcutaneous injection
Cycle: 4 to 6 weeks on
Rest: 2 to 4 weeks off

Note: Guides treat about 200 mcg per shot as the ceiling: above it, cortisol keeps rising while GH does not.

Conservative

Amount: 100 mcg
How often: 1 to 2 times a day, morning fasted and before bed
Route: Subcutaneous injection
Cycle: 4 to 6 weeks, then switch to ipamorelin or GHRP-2

Standard

Amount: 200 mcg
How often: 1 to 2 times a day
Route: Subcutaneous injection
Cycle: 4 to 8 weeks
Rest: 6 to 8 weeks off

5 days a week

Amount: 100 to 200 mcg
How often: Start at 100 mcg once a day and build to 200 mcg 2 to 3 times a day, Monday to Friday
Route: Subcutaneous injection
Cycle: 4 to 8 weeks on
Rest: 2 to 4 weeks off

Timing: Empty stomach, 2 or more hours after eating: morning, after training, before bed.

Research table: start to maximum

Amount: 100 to 300 mcg
How often: 100 mcg once a day to start, 200 mcg twice a day standard, 300 mcg 3 times a day maximum
Route: Subcutaneous injection
Cycle: 6 to 8 week cycles

Low split dosing

Amount: 50 to 100 mcg
How often: 2 to 3 times a day, 4 to 6 hours apart
Route: Subcutaneous injection
Cycle: 8 to 12 weeks on
Rest: 4 to 8 weeks off

With CJC-1295 no DAC (hexarelin amount; CJC 100 mcg)

Amount: 100 to 200 mcg
How often: 1 to 2 times a day, both in one shot, on an empty stomach
Route: Subcutaneous injection
Cycle: 4 to 6 weeks for the hexarelin part

Water volumes sources use: 1 mL, 2 mL

Use bacteriostatic water, not saline, which one guide says can make it precipitate. The solution should be clear; do not use it if cloudy.

Hexarelin dosage questions

How much hexarelin per shot?

100 to 200 mcg is the center, 1 to 3 times a day. Forum protocols in a 2026 review run 100 to 200 mcg once or twice daily. Guides treat about 200 mcg as the ceiling because cortisol keeps climbing past it while GH does not.

How many units is 100 mcg of hexarelin?

With a 5 mg vial mixed with 2 mL of bacteriostatic water (2.5 mg/mL), 100 mcg is 0.04 mL, or 4 units on a U-100 insulin syringe. Use the calculator for other mixes.

How much water goes in a hexarelin vial?

2 mL is the usual choice for a 5 mg vial, giving 2.5 mg/mL. For a 2 mg vial, 2 mL gives 1 mg/mL. Community users report 1 to 2 mL per 5 mg vial.

How long is a hexarelin cycle?

Guides disagree. Some keep it short, 4 to 6 weeks on and 2 to 4 off. Others, and forum protocols, run 8 to 12 weeks on with about 4 weeks off. The only long human study ran 16 weeks and saw recovery after 4 weeks off.
