Most of my family are on GLPs. A couple of them are on a new drug called retatrutide. This is meant to be a better version of things like Monjouro and has fewer side effects and you retain more of your muscle etc.

However, it doesn’t seem to be available officially anywhere as it is still in clinical trials. They are buying it from someone at the gym.

Does anyone have any experience of this drug?

It will soon become very fashionable not to take them, and unfashionable to be skinny with hanging skin and muscle wastage.

Before semaglutides, being skinny was good, fat (even a little bit) was bad. Now if you are looking skinny weight wise, well you MUST be taking the stuff!

The herd mentality will reverse eventually apart from those who are morbidly obese, which is what it was intended for in the first place.

Maybe people are doing WLIs for their health, not fashion…

I’ve loved Mounjaro but would be very interested in an alternative that’s possibly more effective (and cheaper?). I still have to rely on willpower a lot as despite being on the highest dose, I could do with better appetite suppression.

From what I’ve seen on SM, MJ has better appetite suppression although from what I gather this peptide is better overall (sorry I’ve no idea how it works in any detail) as it affects other receptors.

Thats so weird, I'm sure I remembered her getting it from somewhere else, I sit corrected.

I always felt there was more to this ladies health than had been reported in the media.

People have bought illegal substances from gyms since the dawn of time, every gym I have been a member of has had a side hustle in steroids, they are just expanding their market. It’s hardly a new phenomenon.

I’ve only ever been a member of a David Lloyd gym and it’s a very ‘naice’ branch - never noticed anyone being shady and potentially selling this in there!
where are all these gyms selling dodgy stuff?
I’m not asking for myself or a friend, I’m happy paying for my monthly MJ thanks, just very intrigued… 😂

or they do both? 😆

Not really… retatrutide is still experimental meaning its long-term safety and effectiveness are still being studied which is exactly what clinical trials are for.
COVID-19 vaccines went through full Phase 1-3 trials with tens of thousands of participants then were independently reviewed by the MHRA. After approval, they were given to millions of people, creating one of the most extensive safety datasets ever gathered.
Retatrutide has far less evidence, while COVID vaccines are among the most scrutinised medical products in history.
