S2.2.4 growth-hormone releasing factors
Human studies show short pharmacokinetics and GH release after intravenous administration. They do not establish an approved subcutaneous dose or benefits for anti-ageing, muscle gain, fat loss, sleep or recovery.
The schedules below come from the reference page and commonly circulated community models. They have not been confirmed in controlled trials for these goals.
Topluluk verisi
The reference presents a stepped model. This table records it for context; it is not a starting or escalation plan.
| Community phase | Period | Daily amount | Described timing |
|---|---|---|---|
| Assessment | Week 1 | 100 µg/day | once at bedtime, fasted |
| Titration | Weeks 2–3 | 200 µg/day | once at bedtime or 100 µg AM + 100 µg PM |
| Common model | Weeks 4–8 | 200–300 µg/day | once or twice daily; fasted AM and/or bedtime |
| Extended | Weeks 9–12 | 200–300 µg/day | community continuation if tolerated; sometimes to week 16 |
| Break | 4 weeks | 0 µg | described as an off-cycle |
Not established: no approved schedule supports these subcutaneous amounts, escalation steps, frequencies or breaks. A claimed ceiling around 300 µg and totals up to 900 µg/day are also community claims, not established safety limits.
Eight to twelve weeks followed by a four-week break is commonly cited; some models continue to 16 weeks. Neither the benefit and safety of these durations nor claimed receptor recovery during a break has been clinically established.
These examples only multiply amount per administration by frequency. They do not define an appropriate amount.
| Amount each time | Frequency | Calculated daily total |
|---|---|---|
| 100 µg | once daily | 100 µg/day |
| 100 µg | twice daily | 200 µg/day |
| 200 µg | once daily | 200 µg/day |
| 300 µg | three times daily | 900 µg/day |

The values show only the concentration that would result if the stated vial amount were accurate and the exact fluid volume were added. U-100 means 100 units per 1 ml; one unit is 0.01 ml.
Vial size is not an administration amount
2 mg, 5 mg or 10 mg describes the claimed total amount in the vial. Added fluid changes concentration and volume, not the total micrograms.
| Vial | Fluid | Concentration | 100 µg | 200 µg | 300 µg |
|---|---|---|---|---|---|
| 2 mg | 1.0 ml | 2,000 µg/ml | 0.05 ml / 5 U | 0.10 ml / 10 U | 0.15 ml / 15 U |
| 5 mg | 2.0 ml | 2,500 µg/ml | 0.04 ml / 4 U | 0.08 ml / 8 U | 0.12 ml / 12 U |
| 10 mg | 3.0 ml | 3,333 µg/ml | 0.03 ml / 3 U | 0.06 ml / 6 U | 0.09 ml / 9 U |
Rounded values from the reference. Label, actual volume and syringe scale must be independently verified.

Calculation aid, not dosage or use advice. Incorrect inputs, a different syringe scale, measurement error, dead space or unknown vial content produce incorrect results.
Independently check label, fluid, expiry information and planned volume. Do not use unclear or damaged products.
The reference calls for separate alcohol swabs and sterile single-use materials.
The calculated fluid is described as running down the inside wall rather than being forced directly onto the powder.
The vial is rolled or swirled gently, not shaken, until no visible solids remain.
Cloudy, discoloured or particle-containing solution is discarded. Clarity does not prove sterility or identity.
Record concentration and date. Reliable manufacturer or pharmacy information takes precedence.
An internet guide cannot ensure aseptic preparation. Bacteriostatic water, sterile water and approved product diluents are not interchangeable; benzyl alcohol may be unsuitable for some people.
The source models 200 µg daily from a 10-mg vial with 3 ml fluid: about 50 calculated portions per vial, one vial for four weeks and two for 8–12 weeks. This is not medical planning or a recommendation; affiliate offers were excluded.
Published evidence
Ipamorelin is a synthetic pentapeptide and agonist at the ghrelin/growth-hormone secretagogue receptor GHS-R1a. It triggered GH release in preclinical models.
A small phase-I study in healthy men found dose-proportional PK after intravenous infusion, an approximately two-hour terminal half-life and a single GH episode peaking near 0.67 hours.
Claims of selectivity over ACTH/cortisol derive mainly from rat and swine data. They do not establish safety for subcutaneous self-use or long-term exposure.

Community reports and clinical evidence must remain separate. 'Mild' or 'selective' does not mean safe; FDA highlights major data gaps and potential risks for compounded injectable products.
There is no validated prescribing standard for these community goals. Particularly high-risk or poorly studied situations include:
Seek emergency medical care for breathing difficulty, chest pain, altered consciousness, severe allergic reaction, major visual symptoms or signs of serious infection.
Published evidence
No established Ipamorelin monitoring standard exists for community use. These items are inferred from GH-axis risk and require professional interpretation, not self-diagnosis.
| Marker / observation | Why it matters | Context |
|---|---|---|
| IGF-1 | Downstream GH-axis marker | Interpret with age and baseline |
| Fasting glucose & HbA1c | Potential insulin-sensitivity changes | Professional baseline and trend review |
| Lipid panel | Metabolic context | Not validated as Ipamorelin-specific monitoring |
| TSH & free T4 | Separate thyroid-related symptoms | Interpret clinically |
| Blood pressure, weight, oedema | Fluid retention and cardiovascular context | Symptoms matter more than one value |
| Sleep-apnoea symptoms | GH-axis stimulation may be problematic | Worsening requires review |
The reference suggests review after about 6–8 weeks and every 3–6 months for longer use. These intervals are not an accepted standard and must never delay urgent care.
Published evidence
Evidence is narrow, addresses different questions and mainly uses intravenous administration. It does not validate the community protocols.
| Source | Design | Result | Limit |
|---|---|---|---|
| Raun et al., 1998 | Preclinical; rats and swine | GH secretagogue with relative selectivity in animals | No human safety or community-dose study |
| Gobburu et al., 1999 | Phase I; 40 healthy men; IV infusion | Dose-proportional PK; t½ ~2 h; GH peak ~40 min | No subcutaneous long-term or benefit protocol |
| Beck et al., 2014 / NCT00672074 | Phase II; 117 bowel-surgery patients; IV | No significant efficacy benefit in postoperative ileus | Different population, indication and route |
| FDA PCAC review, 2024 | Regulatory evidence review | Insufficient SC efficacy/safety data; recommendation against 503A inclusion | Regulatory assessment, not individual risk advice |
Conclusion: pharmacological activity is demonstrated. Clinical efficacy and safety are not established for body composition, anti-ageing, sleep, recovery or the described subcutaneous schedules.

Without validated product-specific stability data there is no universal shelf life. The reference lists these community ranges; manufacturer/pharmacy labelling takes priority.
| State | Stated range | Claim / limitation |
|---|---|---|
| Lyophilised powder | −20 °C | source: long term; no universal product confirmation |
| Lyophilised powder | 2–8 °C | source: months; product and packaging dependent |
| Lyophilised powder | room temperature | source: short shipping window/weeks; not a shelf-life guarantee |
| Reconstituted solution | 2–8 °C | source: up to about 28 days; unverified without product data |
| Frozen single-use aliquots | −20 °C | source: 3–4 months; stability/container compatibility unconfirmed |
Protect from light and avoid temperature cycling and repeated freeze-thaw. Discard cloudy, discoloured or particle-containing solutions; a clear solution can still be contaminated or incorrectly constituted.
More fluid changes concentration and ml/U-100 values. Recalculate from the actual volume; do not guess.
Do not use. Visible change may indicate instability or contamination.
Correct conversion is impossible without a reliable total. A label or COA does not automatically prove sterility.
Community models describe resuming rather than doubling. This is not clinical dosing advice.
Remaining shelf life cannot be safely inferred without product stability data. Obtain professional assessment or discard.
Do not solve by further calculation or self-adjustment; pause and seek medical review.

Ipamorelin is not FDA-approved for any human use. Clinical testing is not approval.
The earlier 503A nomination was withdrawn in 2024. FDA still reviewed Ipamorelin and the committee recommended against adding it to the 503A bulks list. Removal from an interim category is not authorisation or approval.
Ipamorelin acetate currently remains in FDA Category 2 for 503B compounding, citing potentially significant safety risks including immunogenicity and missing data for certain injectable routes.
Ipamorelin is expressly listed under S2.2.4 as a GH secretagogue/ghrelin mimetic and is prohibited at all times, in and out of competition.
US compounding categories do not transfer to Switzerland or the EU. Possession, import, supply, use and professional responsibility require current local assessment.
Published evidence
This compares targets, evidence and regulatory context; it is not a selection guide.
| Substance | Primary target | Distinction | Status note |
|---|---|---|---|
| Ipamorelin | GHS-R1a | short GH pulse; human PK available | unapproved; WADA-prohibited |
| GHRP-2 / GHRP-6 | GHS-R1a | older secretagogues; stronger ACTH/cortisol or appetite signals in preclinical comparisons | unapproved; WADA-prohibited |
| CJC-1295 / Mod GRF 1-29 | GHRH receptor | different pathway; communities combine both axes | not FDA-approved; WADA-covered |
| Sermorelin | GHRH receptor | GHRH analogue with its own regulatory history | check current local product status |
| Tesamorelin | GHRH receptor | approved for one defined US indication; not interchangeable | FDA approval only for specified HIV lipodystrophy indication |
The reference mainly mentions combinations with GHRH analogues. No validated safety or efficacy protocol exists for these community stacks; effects and adverse effects may add up.
No. It has no FDA-approved human use or approved dose for the goals discussed here.
No. It is the claimed total vial amount. A single volume also depends on added fluid.
U-100 means 100 units per ml. Calculate concentration from vial amount and fluid, then target amount ÷ concentration × 100.
The reference describes 100–300 µg per administration, one to three times daily and 8–12-week cycles. These are unvalidated and not recommendations.
Published research has not established sex-specific subcutaneous standard dosing for these community goals.
The reference says about 28 days refrigerated. Without product-specific stability data this is not a reliable guarantee.
Mainly IGF-1, fasting glucose/HbA1c, lipids, thyroid markers, fluid retention and sleep-apnoea symptoms. No validated community monitoring standard exists.
No. The 2026 WADA List expressly names Ipamorelin and prohibits it at all times.
No. Depending on scope it may describe identity or purity, but does not automatically prove content, sterility, endotoxins, stability or clinical suitability.
