The data
What r/Retatrutide actually talks about
Mostly, people talk about doses.
Retatrutide is Eli Lilly's investigational weight-loss drug. It is not approved anywhere, and Lilly plans to file for approval in early 2027.[1] A large community is using grey-market vials anyway, and much of it talks on Reddit.
We pulled every post in r/Retatrutide from Oct 14, 2025 to Oct 13, 2026: 47,748 of them.[2] We coded each against 44 keyword themes, then did the same for 33,342 comments in the 130 most-discussed threads.
Dose and titration talk appears in 46.4% of posts and in every one of the 130 sampled threads. We report that as a number only. This page contains no dosing information.
Top 10 themes in r/Retatrutide posts
Share of 47,748 posts matching each keyword theme, Oct 2025 to Oct 2026
Side effects are a smaller slice than you might expect.
The table below sets each side-effect theme against two samples: all posts, and the 33,342 comments in the busiest threads. Comments skew toward argument and advice, so the ranking shifts between the two columns.
| Side-effect theme | Posts | % of posts | % of comments |
|---|---|---|---|
| Nausea / vomiting | 2,382 | 5.0 | 0.8 |
| Mood / anxiety / depression | 1,723 | 3.6 | 1.7 |
| Fatigue | 1,438 | 3.0 | 1.0 |
| Anhedonia / libido loss / emotional flatness | 1,374 | 2.9 | 2.2 |
| Heart rate / palpitations | 1,102 | 2.3 | 0.7 |
| Dehydration / electrolytes | 988 | 2.1 | 0.7 |
| Diarrhea | 785 | 1.6 | 0.2 |
| Sulfur burps / reflux | 781 | 1.6 | 0.2 |
| Skin sensitivity (“skin hurts”) | 621 | 1.3 | 0.5 |
| Headache | 619 | 1.3 | 0.2 |
| Constipation | 598 | 1.3 | 0.6 |
| Blood pressure | 414 | 0.9 | 0.4 |
| Injection-site reaction | 396 | 0.8 | 0.3 |
| Sleep problems | 316 | 0.7 | 0.2 |
| Gallbladder / pancreatitis | 168 | 0.4 | 0.3 |
| Hair loss | 161 | 0.3 | 0.3 |
These are mentions, not experiences
A post counts if it matches a keyword rule, so “no nausea at all” still counts as a nausea mention. We spot-checked 8 random hits per theme and tightened weak rules. Side-effect rules looked precise; market rules are rougher.
Keywords miss context, so we also read the opening post of all 130 sampled threads and gave each one a primary topic.
| Primary topic | Threads | Share |
|---|---|---|
| Side effects and adverse experiences | 32 | 24.6% |
| Results and transformation showcases | 22 | 16.9% |
| Sourcing and market (price, scams, customs, tests) | 21 | 16.2% |
| How-to and dosing questions | 20 | 15.4% |
| Legitimacy, stigma and disclosure | 10 | 7.7% |
| Community meta and humor | 9 | 6.9% |
| Non-response (“doesn't work for me”) | 6 | 4.6% |
| Long-term use, stopping, regain | 6 | 4.6% |
| Comparisons and new competitors | 4 | 3.1% |
Side effects lead. Of those 32 threads, 7 were about mood or emotional flattening, 4 described ER or hospital visits, and 4 were dosing or vial-strength errors (a fifth was satire and is excluded).
The surprise
Retatrutide and feeling nothing
The side effect nobody advertises is flatness.
1,374 posts (2.9%) mention anhedonia, libido loss or emotional flatness. That is more than heart rate (2.3%) or skin pain (1.3%), the two effects that show up in the trial data covered in our retatrutide expert opinions roundup.
In the comments the gap widens. Flatness shows up in 2.2% of sampled comments, ahead of mood or anxiety (1.7%), fatigue (1.0%) and nausea (0.8%). It is the most-discussed side effect in the busiest threads.
My personality has changed and I've turned into an emotionless robot.
Users describe dating apathy, lost libido and hobbies that stopped appealing. Seven of the 32 side-effect threads in our hand-coded sample were about this.
Then there is the flip side.
Some users credit the same dampening with switching off cravings. 1,586 posts (3.3%) mention alcohol, and 184 explicitly describe drinking less or stopping. Another 399 describe cravings for weed, nicotine, gambling or shopping going quiet.
10 years smoking weed, woke up after a month on Retta and stopped, no cravings, no withdrawal, just stopped.
On YouTube the craving story is louder still. In 400 comments we read across five popular videos, 30 (7.5%) were about alcohol, addiction, bingeing or cravings, and these were among the most-liked.[3]
Helped me insanely with almost killing completely my alcohol desire, this stuff is awesome
Neither direction is established. These are self-reports with no baseline, and we cannot tell from posts whether the same people experience both.
In their words
Retatrutide side effects Reddit users describe
Fatigue starts the most arguments.
Fatigue appears in 3.0% of posts. A recurring fight is whether it comes from the drug or simply from eating less.
Reta fatigue is real and I am NOT in a calorie deficit.
Skin that hurts
621 posts (1.3%) describe skin that burns, stings or hurts to touch. Several users compare it to sunburn. One poster quit over it.[4]
Ah, the old full-body sunburn feeling! Every piece of my skin would feel hypersensitive and just this side of painful for a couple days.
Heart rate and HRV
Heart rate or palpitations come up in 1,102 posts (2.3%). Blood pressure adds 414 more.
My resting heart rate is 10 beats higher than it was and my hrv is about 30% lower.
For some, that settles it. 646 posts describe switching from tirzepatide to retatrutide, and 300 describe switching back. A March thread titled “Hot take: Tirzepatide is superior to Reta” argued that better sleep beat faster loss.[5]
The stomach
Nausea or vomiting is the most-mentioned side effect in posts (5.0%), followed among GI complaints by diarrhea (785 posts), sulfur burps or reflux (781) and constipation (598). In comments, though, nausea drops to 0.8%. It is a common complaint, but rarely what the long threads are about.
When people stop
864 posts discuss stopping and 2,135 discuss maintenance or regain. The stories we read describe a gradual return of appetite rather than a crash.
Around week three, the food noise started creeping back. Not all at once, more like background music slowly getting louder.
The non-responders
Six of the 130 top threads were about the drug simply not working, and 2,150 posts (4.5%) mention a plateau, stall or gain.
I don't understand how I lost 50 pounds on triz but nothing on the “best shot ever”
The market
How the retatrutide grey market works on Reddit
Officially, nobody names a seller.
r/Retatrutide rules bar naming vendors, and users report bans for pointing to sources. In our 130-thread sample, no vendor name appeared more than five times. Vendor or source talk still shows up in 8.2% of posts.
The rule pushes sourcing into private messages, and a genre of warnings follows: posts titled “DMs are how you get scammed”,[6] scammer alerts and first-person losses. One user described paying and then hearing nothing: “That was the last I heard from them after completing the transaction.”[7]
The keyword counts sketch the rest of the economy:
- Scam, non-delivery or fake product: 985 posts (2.1%).
- “Grey” or “gray” market wording: 880 posts. China or “kits”: 915.
- Telegram: 132 posts. Crypto, Zelle or PayPal: 136. Stockpiling: 149.
- Customs, seizure or package problems: 410 posts (0.9%). One user claimed their Global Entry was revoked after a package was seized; that is unverified.[8]
- Product looks wrong (cloudy, particles, won't dissolve): 662 posts (1.4%).
Cost itself comes up in 5.3% of posts and 5.3% of comments. Our retatrutide price history tracks what vials have cost over time.
Everyone says test. Almost nobody names a lab.
“Test your vials” is the community's standard advice. Yet only 220 of 47,748 posts (0.46%) name a testing lab: Janoshik 203, Finnrick 39, Freedom Diagnostics 10 and Vanguard 5 (some name more than one). Of those 220, 55 use pass or “99%” language and 11 report failures, including 0% purity, contamination and the wrong drug.
Testing is crowd-funded. Users pool money for group tests that reportedly cost $30 to $50 per person.[9] Because vendors can't be named, the results mostly circulate off-platform.
Just seen a COA of Retatrutide 10mg that was eventually Semaglutide.
Purity is not the only gap. Users complain that Janoshik's standard tests don't cover endotoxin or sterility. Endotoxin comes up in 67 posts and 114 comments, and a thread titled “Finally, a failed endotoxin test” drew 254 comments, with commenters claiming it was the lab's highest reading ever.[10] One comment elsewhere said a second lab, Krause, found no retatrutide in a batch Janoshik had passed.
My test reports from janoshik don't test for bacteria.. just curious peoples thoughts on this I'm kind of nervous to keep using grey now
If you are comparing vendor prices and certificates rather than forum hearsay, our retatrutide for sale table lists price per mg next to each batch certificate. Our COA testing study checks 307 vendor certificates against 200 independent tests.
Safety
Vial mix-ups and ER visits in retatrutide posts
A recurring injury story starts with arithmetic.
381 posts (0.8%) mention an ER or hospital visit. A broad keyword rule found 330 posts about dosing errors or vial-strength mix-ups, and 30 that spell out taking one amount when another was intended.
The pattern repeats: a new vial of a different strength from the last one, confusion between volume and weight, or clinic patients given amounts in “units” rather than milligrams. It shows up in the trial-participant subreddit too, where one poster reported two ER visits.
Turns out 1 ml and mg aren't the same thing.
The same story is spreading on TikTok. Lyndsey Jones (@Lyndz99) told followers she had been to the ER twice, with the warning “Never take your reta before you're supposed to.”[11]
Why we publish no numbers here
These stories are reported as a warning pattern only. Grey-market vials are sold for laboratory research, carry no approved label and vary in strength, which is exactly how these errors happen. We do not give doses, conversions or mixing instructions.
Outside Reddit, the counts are rising
CBS News reported on Oct 13, 2026 that the FDA's adverse event database holds two death reports listing retatrutide as a suspect product. One vial was labeled “AlphaLabs”, a company that denies selling it. Neither report establishes that the drug caused a death.[1]
The same piece cites America's Poison Centers: 862 retatrutide exposures in the three months to September, up from 460 the quarter before.[1] In July, The BMJ published a fact-check on an earlier death in the UK.[12]
After Aug 12
How Reddit reacted to Lilly's retatrutide lawsuits
Lilly sued six sellers on Aug 12, 2026.
The targets were Aesthetic Envy, Astra Peptides, Legendary Peptides, Striker Pharmacy, Texas Peptides and Lone Star Peptide. Lilly said it had flagged more than 14,000 listings and posts, referred more than 200 parties to authorities, and was pressing payment processors and shippers.[13][14] CBS reports that Lone Star, Texas Peptides and Aesthetic Envy took their retatrutide pages down.[1]
On Reddit, the spike was short. Only 26 posts all year name the lawsuits explicitly, all from August on. A broader rule (Lilly, lawsuit, stock up) peaks at 14 posts in ISO week 33, Aug 10 to 16, against a baseline of 2 to 5 a week.
Volume did fall. r/Retatrutide had 4,570 posts in the 30 days before Aug 12, then 3,754 in the next 30 days (-18%) and 3,183 in the 30 after that (-30%). But the sub had already peaked in May at 5,096, and r/RetatrutideWomen hit its own high of 1,132 posts in August. That fits migration and other causes as well as deterrence.
The mood was defiant. Users treated the suits as a supply risk, not safety news: stock-up threads, talk of crypto payments, and at least one supplier emailing customers that it would stop selling retatrutide.
China will never stop
One twist: a user posted “So posts from here are now exhibits in a federal filing.”[15] That post and a PeptidesInsider write-up both say the Striker complaint quotes adverse-event posts from r/Retatrutide and r/Biohacking by username and title.[16] We have not verified this against the filing. For the full set of suits and letters, see is retatrutide legal.
Beyond one subreddit
The two internets of retatrutide
Where you read decides what you hear.
In r/Peptides, retatrutide appears in 15.7% of all posts. That beats GHK-Cu (11%) and BPC-157 (8.4%), making it the most-mentioned compound there, and 30.6% of those posts discuss stacking it with other peptides. In r/Zepbound, a community of prescription patients, it appears in 96 of 49,189 posts: 0.20%.[2]
Share of posts that mention retatrutide
All posts, Oct 2025 to Oct 2026
On r/Zepbound it is mostly a future option: will you switch once it is approved? On r/Peptides it is a compound you already own.
What doctors don't hear
Telling a doctor comes up in just 69 posts and 73 comments. The top-voted reply in one disclosure thread (166 points) advised not mentioning retatrutide at all, and people cite worries about insurance and life-insurance records.
I did and regretted it. I wanted to be transparent. Instead they grilled me on where I'm getting it
Surgery or anesthesia comes up in 315 posts. That is where silence matters most, because a surgical team can only plan around the drugs it knows about.
Some clinics and doctors sell it openly.[1] A thread about a Houston primary care doctor offering retatrutide drew 595 comments, the most of any thread this year. The top reply (302 points): “Lol this aint a doctor - this is a dealer”.[17]
YouTube does the recruiting
The top retatrutide videos each have 0.3 to 0.95 million views. Dr. Ashley Froese has 945,303, Dr. Amin Hedayat 895,782, Jacob Nachinson 650,438 and Nicholas Trigili 597,549. Many descriptions carry affiliate or telehealth links.[18]
The skeptics get reach too. Adrian Crook's “I Quit Retatrutide” has 312,797 views, and its description mentions losing 10 lbs of muscle on a DEXA scan.[3] Ryan Sims argues that “losing weight and actually improving your body and health aren't necessarily the same thing.”[19] Mark Plummer explains “why I actually look and feel better without it.”[20]
Creator slang doesn't always travel. Nachinson's description says retatrutide is “often called the ‘Hard R’”.[21] We found zero Reddit posts using that term. Reddit's code names are “GLP-3” (133 posts) and “R3TA” or “RE7A” (106).
The people who got it legally
r/RetatrutideTrial, a smaller sub of self-reported trial participants, had 354 posts in the window.[22] They guess whether they got placebo, and one reported being pulled from TRIUMPH-5 over calcitonin.[23] Their post-trial regain stories echo the ones above.
I knew, my site warned me, that food noise would come roaring back.
Method
How we did this, and its limits
This is a census plus a close read.
- Source. Reddit's own endpoints were blocked, so all Reddit data comes from the Arctic Shift archive.[2] YouTube data comes from public search and watch pages. We logged in nowhere and posted nothing.
- Window. Oct 14, 2025 to Oct 13, 2026. All 47,748 r/Retatrutide posts, plus all posts in r/RetatrutideWomen (7,950) and r/RetatrutideTrial (354).
- Removed posts. 8,870 posts (18.6%) had removed or deleted bodies, so only their titles were coded. The archive may also miss posts moderators removed quickly.
- Comment sample. The top 10 threads by comment count in each calendar month (13 months, both ends partial), stratified so no single news spike dominates: 130 threads, 33,342 comments. We ranked by comments because archived scores are sometimes frozen at ingestion.
- Coding. 44 regex themes, spot-checked with 8 random hits each. All 130 opening posts were also hand-coded. We read about 15 threads' top comments and about 40 other items in full; the rest is regex only.
- Limits. Every Reddit and YouTube statement is an unverified self-report. People with strong experiences post more, and products in these posts are unregulated, so a reported effect may come from a contaminated or mislabeled vial. One satire post was excluded from quotes.
FAQ
Frequently asked questions
What do Reddit users say about retatrutide side effects?
In 47,748 r/Retatrutide posts from the past year, the most-mentioned side effects were nausea or vomiting (5.0% of posts), mood or anxiety (3.6%), fatigue (3.0%), emotional flatness or libido loss (2.9%) and heart rate (2.3%). Skin pain described as a sunburn feeling appeared in 1.3%. These are keyword mentions, not confirmed experiences, and none of it is verified.
Is r/Retatrutide a reliable source of information about retatrutide?
It is a useful record of what self-experimenters report, but not evidence. Every post is an unverified self-report, the products discussed are unregulated research chemicals, and people with strong experiences post more than people with ordinary ones. Use it to learn which questions to ask, not to decide anything about your health.
Why don't Reddit users name retatrutide vendors?
The subreddit bars naming sources, and users report bans for pointing to them. In our 130-thread sample no vendor name appeared more than five times. The side effect of the rule is that sourcing moves to private messages, where users report a steady stream of scams and non-delivery.
Does retatrutide cause anhedonia or emotional flatness?
No trial has established that, but users report it often. 1,374 r/Retatrutide posts (2.9%) mention anhedonia, libido loss or emotional flatness, more than mention heart rate. Other users describe the same dampening as helpful when it quiets alcohol, weed or shopping cravings. These reports are unverified and have no control group.
What happens when people stop retatrutide, according to Reddit?
The most common report is that appetite and food noise return, usually gradually over a few weeks. 864 posts discuss stopping and 2,135 discuss maintenance or regain. Self-reported trial participants describe the same thing after their studies ended.
How did Reddit react to Lilly's retatrutide lawsuits?
Mostly with defiance. Lawsuit-related posts spiked to 14 in the week of Aug 10 to 16, 2026, and users framed the suits as a supply risk rather than safety news. Post volume fell 18% and then 30% in the following months, though it had already peaked in May and the women's subreddit hit its high in August.
