AOD-9604 user experiences: what users themselves report
Users’ own accounts, not research. The accounts are self-selected and prove neither that it works nor that it is safe.
This page does not list users’ doses or sellers, and no figure on it is a recommendation. Doses used in studies, with sources: AOD-9604 dosage in studies.
In short
Of 41 people, 25 (61%) said AOD-9604 brought some benefit and 12 (29%) some harm.
- An AI model read and classified 226 public Reddit posts one by one, following written instructions. Leaving out posts that looked like marketing, 43 were first-hand accounts, from 41 different people.
- Benefits mentioned most often: fat or weight loss (19, 46%) and less joint or cartilage pain (1, 2%).
- Harms mentioned most often: injection site pain or reaction (6, 15%), anxiety or restlessness (1, 2%) and fatigue (1, 2%). In addition, 5 (12%) described some other, rarer harm. People tend to post when something goes wrong, so this share does not tell how common harms are.
- There are only 41 people, just above the publication threshold (40), so the shares are uncertain. 32 of 41 people (78%) used other substances at the same time, most often ipamorelin (11), tirzepatide (10) and CJC-1295 (9). So the reported fat loss cannot be attributed to AOD-9604.
- The accounts cannot separate the substance from placebo or other causes. What the research shows: AOD-9604: what the research shows.
Where the accounts come from and how we read them
Sources: the Reddit forums r/Peptides (32 accounts), r/Biohackers (8), r/Retatrutide (2) and r/bpc_157 (1), 1 Nov 2024 to 29 Sep 2026. The posts were retrieved from a public Reddit archive. From first-person posts about AOD-9604, 226 were picked at random, and every one was read.
Coding: for each account we recorded the route, reported benefits and harms, how strong a harm was, whether and why the person stopped, length of use and other substances used at the same time. We kept accounts that reported some effect, some harm, or no effect. Questions and plans were left out. A harm was recorded when the person reported it during use, even if the cause was uncertain. Several posts by one person count as one person. One person can mention several things, so the shares in the tables do not add up to 100.
Check: an AI model read and classified the posts following written instructions. A second, separate AI run classified a random tenth (23 posts) again without seeing the first classification. The main fields matched: 22/23 (96%). One post looked like marketing and is not in the figures.
Whose accounts these are: routes mentioned: injection 39; the others did not say. The figures describe the writers and are not a recommendation. The products were not verified, so we do not know what people actually took.

Harms known from research and regulators: What are the side effects of AOD-9604?
How long did people use AOD-9604?
26 of 41 people (63%) said how long they had been using it at the time of writing. Where one person wrote several posts, the longest stated time counts.
| Stated length of use | People | Share |
|---|---|---|
| Under a week | 5 | 19% |
| 1-4 weeks | 4 | 15% |
| 1-3 months | 16 | 62% |
| Over 3 months | 1 | 4% |
Many people post partway through, often in the first days or as soon as harms start, so short times are over-represented. The numbers describe the writers; they do not say how long it should be used.
Other substances at the same time
32 of 41 people (78%) used other substances at the same time. The most common: ipamorelin (11), tirzepatide (10) and CJC-1295 (9). Then the account cannot tell which substance had the effect.
About dosing
We do not repeat the amounts or ways of use people mention, and we give no dosing or how-to instructions. A safe dose is not known. Doses used in studies, with sources: AOD-9604 dosage in studies. Legal status: Is AOD-9604 legal in Finland?
What can be concluded?
Fat loss was the most common reported benefit, but most used other substances at the same time, often weight-loss drugs or growth hormone peptides. There are few people, so the shares are uncertain.
The accounts prove neither that it works nor that it is safe. The writers are self-selected, the product contents are unknown, many used several substances at once, and placebo effects can be large. The research and its evidence levels: AOD-9604: what the research shows.
Quotes
Short excerpts in the writers’ own words. Writers’ names and links are not shown. We picked quotes from every group: benefit, both benefit and harm, no effect, harms and people who stopped.
-
"recently added AOD to break a stall, which it has."
r/Peptides, 2025-06, Injected alongside tirzepatide, on which the writer had already lost a lot of weight. Fat loss was by far the most common benefit reported, but other compounds were almost always involved.
-
"In January of this year, I began taking AOD and within a month I noticed I had not gotten anymore swelling. In two it was gone."
r/Biohackers, 2026-08, Injected. Long-standing swelling disappeared, came back when use was paused and went again on restarting. A single, unusual report.
-
"Lost 15 pounds. Only lost an inch off my mid-section but all the fat seemed to come off my back and onto my but lol."
r/Biohackers, 2026-04, Injected for about two months alongside a GLP-1 drug. The writer rates the effect as middling and also reports a stiff back.
-
"Fat loss claims are everywhere with this one, but I saw no measurable difference. Scale, mirror, how clothes fit, all unchanged."
r/Biohackers, 2025-12, Injected before starting a GLP-1 drug. The writer tried compounds one at a time and had regular blood tests.
-
"Just started AOD 9604 but HOLY HELL does it burn like a sonofabitch."

r/Peptides, 2026-05, A ready-mixed blend of AOD with tesamorelin, ipamorelin and MOTS-c, injected for four weeks. The writer says it helped the stomach area, but which compound caused the reaction is unknown.
