Sermorelin ipamorelin dosage explained: typical stack amounts, 5mg/5mg and 10mg blends, timing, cycle length, and safety notes for US researchers.
A typical researched sermorelin ipamorelin dosage is 100-300 mcg of each peptide taken once daily, usually before bed. Most protocols match the two compounds at equal amounts, so 200 mcg of sermorelin plus 200 mcg of ipamorelin is one of the most commonly cited nightly starting points. Neither peptide is a cure for any condition, and neither is approved for general anti-aging or body-composition use in the United States.
What the Sermorelin and Ipamorelin Stack Does
Sermorelin is a synthetic copy of growth hormone-releasing hormone (GHRH). It prompts the pituitary to release growth hormone in the body's own pulsatile pattern rather than replacing the hormone itself.
Ipamorelin is a growth hormone secretagogue that acts on the ghrelin receptor. Early research described it as relatively selective, meaning it produced smaller spikes in cortisol and prolactin than older secretagogues such as GHRP-6.
Stacking the two hits the same endpoint from two different receptor pathways: one GHRH signal and one ghrelin-receptor signal. Because the mechanisms are separate, most sermorelin/ipamorelin stack dosage protocols stay in a modest range instead of escalating both compounds at once.
Typical Sermorelin Ipamorelin Dosage Per Day
The ranges below reflect what appears most often in research summaries and clinician-guided programs. Guidance from a licensed healthcare professional should always take priority over a generic chart.
| Protocol level | Sermorelin | Ipamorelin | Typical timing |
|---|---|---|---|
| Conservative starting dose | 100 mcg | 100 mcg | Once daily, 30-60 minutes before bed |
| Common mid-range dose | 200 mcg | 200 mcg | Once daily, before bed |
| Higher end of range | 300 mcg | 300 mcg | Once daily, or split into two smaller doses |
A frequently cited ceiling is 300 mcg per peptide per day, or 600 mcg combined. Splitting the dose into a morning and a pre-bed injection is sometimes discussed, but most protocols use a single nighttime dose because natural growth hormone release peaks during deep sleep.
Body weight, age, training load, and side effects all shift the number in practice. A cjc 1295 ipamorelin dosage calculator female users rely on is only a rough math tool, and any sermorelin ipamorelin dosage per day posted in a forum deserves the same skepticism.
Sermorelin/Ipamorelin 5mg 5mg Blend Dosage and 10mg Blend Dosage
Blended vials cause most of the confusion. A 5mg/5mg blend contains 5 mg of sermorelin and 5 mg of ipamorelin, for 10 mg of total powder. The phrase sermorelin ipamorelin 10mg blend dosage usually refers to that same 10 mg total, but some vendors sell a vial that is 10 mg of each peptide, which is a very different amount.
Always read the label before doing the math. In a true 1:1 blend, every milligram of powder contains 0.5 mg of each peptide, so a 400 mcg draw delivers 200 mcg of sermorelin and 200 mcg of ipamorelin.
Reconstitution volume, not vial size, determines how many units you draw. The table below shows the math for a 5mg/5mg (10 mg total) vial.
| Reconstitution volume | Concentration | Draw for about 200 mcg of each | Draw for about 300 mcg of each |
|---|---|---|---|
| 1 mL | 10 mg/mL | 4 units (0.04 mL) | 6 units (0.06 mL) |
| 2 mL | 5 mg/mL | 8 units (0.08 mL) | 12 units (0.12 mL) |
| 3 mL | 3.3 mg/mL | 12 units (0.12 mL) | 18 units (0.18 mL) |
These figures are educational only and assume U-100 insulin syringes. They are not dosing instructions, and anyone using these compounds should confirm every number with a licensed clinician.
Timing, Frequency, and Cycle Length
Why nighttime dosing is standard
Growth hormone is released in pulses, with the largest pulse shortly after sleep begins. Dosing sermorelin and ipamorelin 30-60 minutes before bed is intended to line up with that natural window.
Food can blunt the response, so most protocols call for an empty stomach, typically two hours after the last meal and at least 30 minutes before eating again.
How long people typically run the stack
Common cycles run 8 to 12 weeks, sometimes with a 5-days-on, 2-days-off weekly pattern. A break of 4 to 8 weeks between cycles is frequently recommended so the pituitary is not continuously stimulated.
Because sermorelin and ipamorelin raise endogenous growth hormone, IGF-1 is the marker most often tracked during a cycle. Baseline and mid-cycle blood work gives a clinician something concrete to evaluate.
Safety, Side Effects, and Legal Status in the US
Ipamorelin is not FDA-approved for human use in the United States. Sermorelin previously had an FDA-approved diagnostic product that has since been discontinued, and compounded sermorelin has faced regulatory restrictions in recent years.
Reported side effects include injection-site irritation, headache, flushing, dizziness, and fatigue. Compounds that raise growth hormone can also cause water retention, joint aches, and tingling in the hands and wrists.
These peptides are not appropriate for people with active cancer, pituitary disease, or uncontrolled diabetes, or for anyone who is pregnant or breastfeeding. Blood sugar, IGF-1, and thyroid markers should be monitored by a healthcare professional rather than self-managed.
How It Compares With CJC-1295 and Other Options
Sermorelin has a very short half-life, measured in minutes, while CJC-1295 with DAC stays active for days. That difference is why many researchers also look into cjc-1295 ipamorelin dosage when they want fewer injections or a longer signal.
A sermorelin ipamorelin cjc1295 dosage comparison usually comes down to duration rather than total amount. The three-peptide approach is generally discussed for advanced protocols, not for beginners.
Labels vary between vendors, and a vial marketed with cjc 1295 ipamorelin 10mg dosage labeling is usually 5 mg of each peptide in a single vial. That is a labeling convention, not a guarantee.
Forum threads such as ipamorelin/cjc-1295 dosage reddit discussions mix personal experience with protocol suggestions, so treat them as anecdote rather than evidence. Even carefully formatted posts cannot replace blood work and medical oversight.
Frequently Asked Questions
What is a typical sermorelin ipamorelin dosage per day?
Most protocols use 100-300 mcg of each peptide once daily, taken 30-60 minutes before bed. A common middle ground is 200 mcg of sermorelin plus 200 mcg of ipamorelin, for 400 mcg combined. Splitting the dose into two smaller injections is sometimes discussed, but a single nighttime dose is the standard approach.
How do I dose a sermorelin/ipamorelin 10mg blend?
A 10 mg blend is usually a 5mg/5mg vial, meaning 5 mg of each peptide. In a 1:1 blend, a 400 mcg draw gives 200 mcg of sermorelin and 200 mcg of ipamorelin. The number of units you draw depends on how much bacteriostatic water you added, not on the total vial size.
Are sermorelin and ipamorelin FDA-approved?
Ipamorelin is not FDA-approved for human use in the United States. Sermorelin had an FDA-approved diagnostic product called Geref, but it has been discontinued, and compounded sermorelin has faced regulatory restrictions. Anyone considering either peptide should speak with a licensed healthcare professional first.
