That Gabriel Iglesias Ozempic clip is everywhere today. Five months on it, he says it curbed his appetite and he lost more muscle than fat. He quit and 20 pounds came back fast.
In the STEP 1 trial, people who stopped semaglutide regained about two-thirds of the loss in a year.
At a Chinese plant making GLP-1 ingredients for compounded shots, FDA inspectors saw staff pour samples down the sink and hide lab papers. Black mold. Insects in the ceilings.
Per Bloomberg and USA Today. It's now on an FDA import alert.
Did you know where those come from?
In a randomized trial in NEJM, retatrutide cut sleep apnea events by about 32 to 34 an hour at the top doses after 80 weeks. Placebo: about 10.
243 people with obesity and sleep apnea, part of TRIUMPH-1.
Still not approved. The vials sold online were never in that trial.
Same day: TikTok searches for BPC-157, retatrutide and even semaglutide started returning "no results found" (per The Verge), and RFK Jr. said the administration aims for a regulated peptide market where "the factories are inspected" (per Reuters).
The policy text isn't public.
"GLP-1 injections recalled nationwide." Per USA Today: 22 vials (possibly 22 lots) of compounded tirzepatide, Class II, for "lack of assurance of sterility."
Not brand-name drugs. FDA warned that same pharmacy about sterile practices last December.
Know your source.
Novo says women on CagriSema lost 25% of body weight on average at 68 weeks, vs 3% on placebo. 7 in 10 lost at least a fifth.
Fine print: a look-back analysis that assumes everyone stayed on the drug. Over half in the trial got nausea. Not FDA approved.
Hype or real?
A pro-peptide medical group meets the White House budget office Wed. on FDA's pending peptide compounding plan.
In July, FDA scientists raised concerns. Advisers narrowly voted yes anyway.
Ex-FDA chief Scott Gottlieb weighed in on CNBC.
The policy text isn't public. Who wins?
Australia just counted the peptide boom in ER visits.
NSW alone: 1,180 visits associated with unapproved peptides in 15 months. 5 a month became 217 in September.
71% mentioned retatrutide. Not approved in Australia or the US.
A label isn't proof of what's inside.
Taleb says GLP-1 users lose their gusto. Opinion, 280K views.
JAMA Psychiatry 2025: 80 trials, 107,860 people. Better mental-health quality of life. No rise in psychiatric side effects.
They hit reward circuits. Although anecdotal, users report food feels flat. Gap: anhedonia.
Huberman asked which peptides join GLP-1s as certified USA-made.
There's a shortlist. FDA's advisers backed six in July: BPC-157, KPV, TB-500, MOTS-c, Epitalon, Semax. Three were 8 to 6. FDA scientists said none.
None can be compounded yet. White House meeting Wednesday.
Two deaths were reported to FDA after people used bootleg retatrutide. Cause not confirmed.
On record: WSJ says 50+ companies that sold fentanyl ingredients now sell peptides. Bloomberg says FDA found black mold at a Chinese plant making GLP-1 ingredients.

Bloomberg says the new shortcut to a sharper mind is brain peptides, mainly Semax.
Not FDA approved. Human data is mostly small Russian stroke studies. FDA flagged immune risk. Although anecdotal, users report less brain fog.
Doctors are fighting to keep it out of pharmacies.
Peptides have to be injected, right? Merck just made one a daily pill, and FDA approved it in July.
It's enlicitide. In the NEJM trial, LDL fell 57% at 24 weeks. Placebo rose 3%. 97% were already on statins. Side effects looked like placebo.
Not shown yet: fewer heart attacks.
BPC-157 is all over gyms and podcasts.
Human evidence a new systematic review could find: 3 studies. 30 people. Total.
All 3 judged poor quality. Certainty: very low.
Although anecdotal, users widely report good results. Stories aren't trials.

Retatrutide isn't approved anywhere. It's showing up by the thousands.
UK, Oct 14: police and MHRA seized 12,000+ fake reta and tirzepatide pens from a "filthy warehouse."
Brazil, September: 572 reta items caught at Rio's airport.
MHRA: "no guarantee of what they contain."
Everyone's posting "peptides are legal." They're not.
AP: two sources call it enforcement discretion. FDA would temporarily not go after pharmacies compounding some popular peptides, BPC-157 included.
Not approval. Not a safety finding. Not in effect.

Over 40 and lost in the peptide rabbit hole for body comp? Sort by evidence, not hype.
GLP-1 class: huge human trials, retatrutide next in line
GH secretagogues: small human studies, big user following
BPC-157, TB-500, MOTS-c: mostly animal data, loud anecdotes
Know the tier.
Retatrutide isn't FDA-approved. Georgia clinics are dispensing it anyway.
The AJC found more than a dozen there that say they can. A pharmacy professor told the paper the ingredient most likely comes from offshore.
Although anecdotal, users report big results. From what?
Peptides women ask us about most:
GHK-Cu: years of research, strong anecdotal backing for hair, skin and nails
Retatrutide: promising Phase 3, FDA filing planned early next year
PT-141: users rave about libido, yet it's approved for one narrow use
Selank: many Russian studies
The "Wolverine Stack" (BPC-157 + TB-500) has gone mainstream. Although anecdotal, users widely report bouncing back faster from nagging injuries.
The science is mostly animal studies. Two human trials now registered, one already recruiting.
Massive hype. Early science.
