Ipamorelin is a synthetic growth hormone releasing peptide that stimulates pulsatile GH secretion from the pituitary gland. Using it correctly requires precise dosing, proper timing, and evaluation by a licensed provider — available asynchronously at TelosRX.

Ipamorelin is not FDA-approved for any human therapeutic use. All use is subject to medical approval by a licensed provider. This guide covers the protocol steps commonly referenced in clinical and research literature; your provider's instructions take precedence over any general guidance.

Step 1: Understand What Ipamorelin Is — and Is Not

Ipamorelin is a pentapeptide growth hormone releasing peptide (GHRP) that selectively stimulates the pituitary to release GH without meaningfully elevating cortisol, prolactin, or ACTH. This selectivity distinguishes it from earlier GHRPs like GHRP-2 and GHRP-6. A foundational study published in Growth Hormone & IGF Research (1998) confirmed ipamorelin's selective GH-releasing action in animal models, with a clean hormonal profile at standard doses.

Ipamorelin is frequently combined with a growth hormone releasing hormone (GHRH) analogue — such as CJC-1295 — to generate a synergistic GH pulse. It is also compared against secretagogues like MK-677 (an oral option) and sermorelin (a GHRH-class analogue). Which approach is appropriate depends on your goals and a provider's clinical assessment of your baseline.

Step 2: Complete a Provider Evaluation Before Starting

Ipamorelin is a compounded medication. It is subject to medical approval by a licensed provider and cannot be legally self-prescribed. Do not adjust dosing, cycle length, or injection frequency without direct provider guidance.

At TelosRX, the process is fully asynchronous — you submit a health history questionnaire and relevant lab values through the patient portal, and a licensed provider reviews your file on their own schedule. There are no required video calls or synchronous appointments. Approval is not guaranteed; providers make an independent clinical determination for each patient. Only proceed with the steps below after a licensed provider has reviewed your file and issued a prescription.

Step 3: Know the Standard Dosing Range

The ranges below reflect protocols described in the published literature. Your provider may prescribe a different dose based on your individual presentation, labs, and goals.

Parameter Common Range
Dose per injection 100–300 mcg
Injections per day 1–3
Cycle length 8–16 weeks
Administration route Subcutaneous injection
Typical starting dose 100–200 mcg, once nightly

Increasing dose beyond the prescribed range does not proportionally increase GH output and may increase the likelihood of side effects without added clinical benefit.

Step 4: Reconstitute the Peptide Correctly

Ipamorelin is dispensed as a lyophilized (freeze-dried) powder requiring reconstitution with bacteriostatic water. Follow your pharmacy's specific instructions. The standard procedure is:

  1. Wash hands thoroughly. Prepare a clean, flat workspace.
  2. Bring both the peptide vial and bacteriostatic water vial to room temperature.
  3. Wipe both vial stoppers with an alcohol swab. Allow to air dry completely.
  4. Draw the prescribed volume of bacteriostatic water into a sterile insulin syringe.
  5. Insert the needle into the peptide vial and inject the water slowly along the inner vial wall — do not spray directly onto the powder cake.
  6. Gently swirl (do not shake) until the powder dissolves completely. The solution should be clear and colorless.
  7. Label the vial with the reconstitution date. Store refrigerated at 36–46°F (2–8°C) and use within 30 days. Discard any vial that appears cloudy, discolored, or contains visible particles.

Step 5: Time Your Injections for Maximum Effect

GH is released in pulses. Strategic injection timing avoids competing with periods of natural GH suppression:

  • Before sleep: The largest endogenous GH pulse occurs during slow-wave sleep. Injecting 30–60 minutes before bed may amplify this pulse.
  • Morning fasted: Insulin suppresses GH secretion. Injecting before eating — in a fasted state — avoids glucose-mediated blunting of the GH response.
  • Post-exercise: Exercise produces a natural GH spike. A third injection in the post-workout window (fasted or low-carbohydrate) is used in some multi-dose protocols.

As a general principle, avoid injecting within 2 hours of a high-carbohydrate meal. Elevated blood glucose and insulin significantly reduce the effectiveness of any GH-releasing peptide.

Step 6: Recognize Potential Side Effects

Ipamorelin is associated with a favorable side effect profile relative to exogenous GH, but adverse effects can occur. Commonly reported effects include:

  • Injection site reactions: Transient redness, mild swelling, or tenderness at the injection site.
  • Headache or lightheadedness: Associated with rapid GH release, particularly at higher doses. Typically resolves within minutes.
  • Mild water retention: Edema can occur during the early weeks of a protocol, often resolving as the body adjusts.
  • Tingling or numbness: Particularly in the hands and wrists — a known correlate of elevated IGF-1. Usually transient.
  • Increased appetite: Less pronounced than with GHRP-6, but reported in some users at higher doses.

Because ipamorelin is not FDA-approved for any human therapeutic use, long-term safety data in humans remains limited. Report any persistent or concerning symptoms to your provider promptly.

Step 7: Monitor Your Response and Follow Up With Your Provider

Effective ipamorelin use involves ongoing monitoring, not a one-time prescription. Key markers typically tracked throughout a protocol include:

  • IGF-1: The primary biomarker for GH axis activity. Measured at baseline and mid-cycle to assess response.
  • Fasting glucose and insulin: To screen for glucose regulation changes.
  • Subjective outcomes: Sleep quality, recovery, body composition trajectory, and energy levels.

TelosRX operates as an asynchronous telehealth service. Follow-up is conducted through the patient portal — you submit labs and symptom updates, and your licensed provider reviews them on their schedule. Providers may modify or discontinue a prescription based on follow-up data. Approval at initiation does not guarantee continuation of a protocol.

Frequently Asked Questions

Is ipamorelin FDA-approved?

No. Ipamorelin is not FDA-approved for any human therapeutic use. It is available as a compounded medication prepared under federal compounding regulations and is prescribed off-label by licensed providers where clinically appropriate.

How long before I see results from ipamorelin?

Improvements in sleep quality are often reported within the first 2–4 weeks. Measurable body composition changes — such as shifts in lean mass and fat distribution — typically appear after 8–12 weeks of consistent protocol adherence. Individual results vary and are not guaranteed.

Can I use ipamorelin without combining it with CJC-1295?

Yes. Ipamorelin functions as a standalone peptide. Combining it with a GHRH analogue like CJC-1295 produces a larger synergistic GH pulse, but many protocols use ipamorelin alone. Your licensed provider will determine the appropriate approach for your clinical picture.

How should I store reconstituted ipamorelin?

Store refrigerated at 36–46°F (2–8°C). Use within 30 days of reconstitution. Do not freeze the reconstituted solution. Protect from light and temperature extremes.

What time of day should I inject ipamorelin?

The most commonly used timing is 30–60 minutes before sleep, aligned with the body's largest natural GH pulse. Some protocols add a morning fasted injection or a post-exercise dose. Follow your provider's specific instructions for your protocol.

Does ipamorelin raise cortisol or prolactin?

At standard doses, ipamorelin does not significantly elevate cortisol, prolactin, or ACTH — a selectivity profile that distinguishes it from earlier GHRPs. This is one reason ipamorelin has remained a preferred research peptide for GH stimulation studies.
