I write a GLP1 newsletter and would love to learn more about what you’re building and how you see the landscape.
Reta looks like it will make it out by early next year but I personally think they’ll squeeze in to end of this year — there will likely never be a undersupply of GLP1s again and I wonder if the customization loopholes will hold (Lilly will certainly fight Reta compounders harder than they have others), interested to hear your thoughts and chat.
There is a large enthusiast community of the body building variety (who are usually first) who are already performing a bit of an unscheduled human trial and I have to say the results are amazing. We have both injectable retatrutide and pill form retatrutide to look forward to (pill form is unannounced but I have a hunch!).
Looks like we posted around the same time, but see:
That said, there are some that have reported it also lessens desire for things they want to desire.
Did a writeup on this back in summer '25:

Addiction comes up in anecdata all the time so I've written about it a few times but these papers are a good place to start to find more rigorous data points.
Eli Lilly has taken to calling GLP1s "anti-hedonics" as well
So weight loss was actually maintained for most people -- the hard part is finding a healthy daily lifestyle which can maintain the drastic effects of GLP1s.
This information isn't new -- weight regain has been studied before and I've written about it before:
https://glp1.guide/content/do-people-regain-all-the-weight-l...
The missing piece to this article is just how bad the alternative is -- never having the cardiovascular and metabolic benefits is clearly not the best strategy (and if simply changing patterns was so easy, people would have done it already).
GLP1s don't work for everyone but they're pretty close to miraculous in effect given the balance of positive and negative side effects. Making GLP1s cheaper & more tolerable then figuring out how to actually deal with the complex web of how to keep the weight off sustainably for most people seems like the right way forward here, not avoiding potentially life-saving medication because you may not be able to get off of it as fast as you want (if you can afford it).
BTW, there is already generic Liraglutide, and legal workarounds for getting compounded Semaglutide that already mean no one pays the $1000 that was in the zeitgeist a while ago. Even Lilly Direct and similar outfits from Novo sell for $500/month, with the $150/month pricing coming soon[0].

Also, a lot of people are still getting compounded GLP1, to the chagrin of Eli Lilly and Novo Nordisk.
Separately, 2026 is about to completely change the pricing of this stuff, not even taking into account the Trump administration's recent efforts. The price of injected GLP1 is going to implode due to patents lapsing in Canada and other places -- and for the pill forms that come out soon it looks like the Trump administration is keen on keeping prices for that low as well.
That said, the negative side effects look to be incredibly rare and manageable (including via stopping treatment) -- and the positives are quite tremendous.
It's not a magic drug, but it is the first of it's kind with such a skew to the positive on side effects.
Both companies have thus far been unable to really stop compounding pharmacies and/or gray market suppliers from replicating though, and price negotiation with the government is definitely going to happen (Trump recently announced wanting $150 GLP1s, Novo's lawsuit against medicare price negotiation failed)... I do not have much faith in their ability to protect their pricing power for very long, which unfortunate for them is probably what's best for humanity and is very well known at this point.
There’s one wrinkle though, legally importing prescription drugs from Canada isn’t really allowed in the US/UK AFAIK. HIMS is probably feverishly figuring out how to do that right now.
Shameless plug:

Also somewhat separately, injectable GLP1s are about to be upstaged by oral variants — orfoglipron for Eli Lilly and the Wegovy Pill for Novo.
The NAION link is tenuous (research was inconclusive, I have written about this before[0]) and gastroparesis is a known side effect.
This was a great chance to learn the name of the vomiting symptom though — will be looking more into “cyclic vomiting syndrome”

GLP1s are certainly not for everyone, and if she had that reaction on a starting dosage then it certainly is obvious stopping was the way to go.
That said, for the vast majority of people though, GLP1s are likely going to the key to living longer and carrying less weight (including into old age). At this point, the research is behind the drugs being useful for the vast majority of the population, and the literal millions of people taking these drugs do not seem to be running into such horrific side effects, especially ones that continue after stopping the drugs.
Would you mind sharing which GLP1 she was on? This actually sounds like something that should be more widely known. Throwing up forever is quite a crippling side effect, and since GLP1s are more recently considered primarily brain drugs, I wonder if it triggered a persistent chemical imbalance.
