Modified GRF 1-29
Mod GRF 1 29 and Ipamorelin names a combination, not a controlled human result. The direct published finding for Modified GRF 1-29 is analytical. PMID 30136411 identified glycine-modified analogs in powders seized by Danish customs[1]. The authors used LC-HRMS and reference standards[1]. PubMed lists no grant for that paper[1]. An exact PubMed clinical-trial search found no human trial of Modified GRF 1-29[4].
What is Modified GRF 1-29, and what exactly does the name identify?
The review naming line records how one review uses the label[2]. It is not a primary structure analysis. Its cited studies concern other GHRH analogues, so their results are not transferred here.
The analytical paper found analogs rather than the expected unmodified targets[1]. The abstract says every detected modification added one glycine at the N-terminus[1]. It does not give a full Modified-GRF sequence or a sample count for that target.
The names can look like one long list for one drug. They are not all the same kind of name. Modified GRF 1-29 is the name used by this record. CJC-1295 without DAC is a name used for it in one review. CJC-1295 with DAC is kept on its own page because the published study names it as long-acting[9].
What has been published in humans?
No controlled human result for exact Modified GRF 1-29 was found in the named searches. The searches are narrow and dated. They do not turn studies of CJC-1295 with DAC, native GHRH, or Ipamorelin alone into evidence for this molecule or combination.
| Search or source | Result | What it establishes | Checked |
|---|---|---|---|

ClinicalTrials.gov lists NCT00267527 for CJC-1295 in 120 participants. It names ConjuChem as the industry lead sponsor. The study status is terminated. No results are posted. Its intervention is CJC 1295, not Modified GRF 1-29.
PMID 16352683 reports randomized trials of long-acting CJC-1295 in healthy adults[9]. Its outcomes are not used as Modified-GRF results. NCT00267527 names ConjuChem as sponsor for its CJC-1295 trial[8]. The long-acting results remain on the CJC-1295 page.
The one PubMed hit with both names is also easy to misread. The paper lists both as targets found in seized powders. It did not give both to a person. It did not test how the pair acts.
What side effects and safety findings were recorded?
No exact-compound human trial was found, so the checked sources provide no controlled adverse-event rate for Modified GRF 1-29. This is an evidence absence, not a claim that no adverse event can occur.
| Source | Recorded finding | Limit | Checked |
|---|---|---|---|
| [1] | The paper reports an analytical finding in powders. | It enrolled no participants and reports no clinical adverse events. | 2026-09-05 |
| [4] | 0 exact trial papers | No exact trial means no trial-derived rate in this search. | 2026-09-05 |
| [15] | The writer reported broken sleep and daytime fatigue during combined use. | Self-reported, mixed with Ipamorelin, and not a rate. | 2026-09-05 |
The Reddit report cannot assign its sleep finding to one compound. Comments from other users do not create a denominator. The full thread remains linked so the reader can inspect each account.
No source in the checked set gives a long-term safety result for exact Modified GRF 1-29. No source in the checked set gives a risk rate for the pair with Ipamorelin.
What dosage information do sources report for Modified GRF 1-29?
The sources below report one self-selected amount and three explicit absences. They do not establish a studied or approved dose for Modified GRF 1-29. No row is a VialFacts protocol.
| Source | Source-reported amount or absence | Context | Checked |
|---|---|---|---|
| [15] | The writer reported 100 mcg of Modified GRF and 100 mcg of Ipamorelin. | Self-reported combined use; product identity and contents were not tested | 2026-09-05 |
| [1] | No human dose is reported. | Analytical study of seized powders | 2026-09-05 |
| [4] | No exact trial dose was found. | 0 records in the bounded query | 2026-09-05 |
| [11] | No approved product dose was returned. | 0 labels for the exact name | 2026-09-05 |
The amounts in CJC-1295-with-DAC trials are not presented as Modified-GRF amounts. The compounds are kept separate because the published CJC-1295 study calls that form long-acting[9].
The 100 mcg line is one person's own report[15]. It was not set by a trial, a label, or a public drug record. The post also names a second drug, so it cannot show what dose of one drug caused the later account.
What do animal and laboratory studies add?
The exact PubMed name search returned only PMID 30136411[3]. It found no exact-name animal experiment. The analytical paper is a laboratory study of material, not an animal efficacy study.
The 2026 review discusses broad GHRH and GH pathways[2]. It does not provide an exact Modified-GRF animal result in the cited naming passage. No mechanism claim from a neighboring molecule is upgraded into a direct finding here.
The useful lab fact is still the powder test. It shows a change in the chain that a broad name on a vial would not show on its own.
What has direct vial or product testing found?
PMID 30136411 is direct material evidence[1]. It answers what the laboratory identified, not what the powders did in a person.
| Source | Measured | Not reported | Funding | Checked |
|---|---|---|---|---|
| [1] | LC-HRMS and reference standards identified analogs of GHRP-2, GHRP-6, Ipamorelin, and modified GRF 1-29 in seized powders. Every detected modification added one glycine at the N-terminus. | No count by target, full Modified-GRF sequence, purity, sterility, endotoxin, label amount, or human outcome appears in the abstract. | The checked PubMed record lists no grant. | 2026-09-05 |
The phrase in all cases applies to the detected modifications across the paper's targets. It does not supply a denominator for Modified GRF 1-29 alone. The paper describes analogs, so it does not prove that a labeled powder contained the expected original sequence.
The paper's LC-HRMS method distinguished the modified analogs with the aid of reference standards[1]. Its abstract reports no sterility test[1]. It also reports no amount for each powder.
This is why the added glycine is useful to know. A near match is not the same fact as the name on a pack. The paper found that gap with a direct test.
What do user reports add here?
The open Reddit thread is self-reported and self-selected[15]. No payment is disclosed. The writer describes two people using both Modified GRF and Ipamorelin, so the account cannot isolate one compound.
We both fall asleep fast, but the sleep quality is shit. Waking up multiple times during the night, then waking up 1.5 hours before alarm... We are only on day 3 but man, am I dragging ass today.
The writer later added an explicit uncertainty:
I notice a better mood during the day. Could be placebo since I am only 5 days in.
The quoted account reports sleep and mood. It does not test GH, IGF-I, body composition, recovery, or product identity. Other comments in the thread are individual replies, not a counted consensus.
The thread also shows why a pair is hard to judge from one post. The writer changed which drug was used at night. The writer then said the mood change could be placebo. Those words keep the doubt in the source instead of asking the page to settle it.
No count was made of all views in the thread. No claim about what most users feel is made here.
What is the current evidence status, and what is the regulatory status?
Evidence tier and regulatory status answer different questions. Search absences stay bounded to their exact names and datasets.
| Question | Current answer | Source and boundary | Checked |
|---|---|---|---|
| Evidence tier | Tier D | Direct analytical evidence exists, but no exact human trial was found in the named searches. | 2026-09-05 |
| Exact PubMed evidence | 1 analytical paper and 0 clinical-trial papers | Exact search and trial filter | 2026-09-05 |
| GSRS exact-name search | 0 results | Exact Modified GRF 1-29 search only[10] | 2026-09-05 |
| DailyMed exact-name search | 0 labels | Exact name only[11] | 2026-09-05 |
| openFDA exact brand search | No match; HTTP 404 response | Exact brand-name query only[12] | 2026-09-05 |
| EMA central report | No mod-GRF 1-29 match in 2,731 medicine rows | Centralized report generated 2026-08-22; not every national route[13] | 2026-08-22 |
| Swedish product file | No mod-GRF 1-29 match in 38,369 product rows | Named Läkemedelsverket file dated 2026-08-22; absence does not classify every product[14] | 2026-08-22 |
| EU status | unclear | The central EMA absence cannot settle every national route. | 2026-09-05 |
| First observed | null | PMID 30136411 reports seized material without a month of seizure; its publication month is not substituted. | 2026-09-05 |
The direct material finding remains useful even with tier D. The tier records the human-evidence gap. It does not erase what the laboratory identified.
The status stays unclear because the named files do not settle all routes. The evidence tier stays D because the exact human study was not found. Those are two different facts.
Where can a reader go next?
- CJC-1295 with DAC in the register - keeps the long-acting DAC studies separate.
- Ipamorelin in the register - reports that compound's own human and product evidence.
- What can be measured in a vial - separates identity, quantity, sterility, and endotoxin questions.
- All register entries - returns to the complete compound index.
