Hexarelin dosage by administration route

Hexarelin injectable dosage

Reported-use amounts for Hexarelin are 100–200 mcg per administration, 1–2x daily, for 4–8 wk.[11]

Hexarelin is a growth-hormone secretagogue that activates the ghrelin receptor. Repeated exposure can change endocrine responsiveness, making frequency and duration relevant to its effects.[1][2][3][11]

Hexarelin intranasal dosage

The documented short-course nasal amount is 1.25 mg per administration, three times daily for 8 days. This is an investigational endocrine schedule, separate from injectable Hexarelin.[5]

Hexarelin is a growth-hormone secretagogue that activates the ghrelin receptor. Repeated exposure can change endocrine responsiveness, making frequency and duration relevant to its effects.[6][1][2][3]

Hexarelin oral dosage

The documented short-course oral amount is 20 mg per administration, three times daily for 15 days. Oral and nasal amounts differ because their delivery and absorption differ.[5]

Hexarelin is a growth-hormone secretagogue that activates the ghrelin receptor. Repeated exposure can change endocrine responsiveness, making frequency and duration relevant to its effects.[6][1][2][3]

Frequency and timing

Morning or bedtime is the listed timing for injections. The oral and nasal preparations each have their own three-times-daily schedules.[4][1][2][5][11]

Cycle length and breaks

Injectable: 4–8 wk. Intranasal: 8 days. Oral: 15 days. A standard break interval between courses is not established.[11][5]

Hexarelin safety and side effects

Approval and product quality

Hexarelin is not an FDA-approved drug.[4][8][9][10]

Side effects and long-term safety

Endocrine effects, glucose changes and injection-site reactions are relevant. Repeated-cycle endocrine safety, long-term glucose effects and product purity remain uncertain.[7]

Route-specific dosing limits

Endocrine, metabolic, and anti-doping contexts drive the main safety decisions. Reported-use injectable schedules are not established human treatment regimens.[7][11]

Common Hexarelin dosage questions

Can Hexarelin doses be transferred between routes?

No. Each route and formulation has its own exposure and administration requirements. Use the dose information for the exact presentation rather than copying a tablet, injection or local-product amount to another route.[4][1][2][5]

What dosage is listed for Hexarelin?

Reported-use amounts for Hexarelin are 100–200 mcg per administration, 1–2x daily, for 4–8 wk.[11]

Does Hexarelin have a standard cycle or break interval?

Injectable: 4–8 wk. Intranasal: 8 days. Oral: 15 days. A standard break interval between courses is not established.[11][5]
