I bought Semaglutide at 50c/mg and had it tested, it's the real deal. What's the normal price, $100/mg? My gf is in medicine so she had a friend test it through their work.

> had it tested, it's the real deal How did they test encapsulation? I thought the whole problem is your stomach acid breaking it down.

They’re presumably injecting it like normal.

Peptides are a revolution and you don't need to know how they work to know that they work (for various people for various conditions). There is a tension between empiricism and fundamentalism with much of medical science focusing on fundamentalism. Now with the ability to collect and search large amounts of empirical data and communicate it peer-to-peer people are picking up on a lot of things that work without knowi…

Have you tried omega3? There were some improvements I was reading about.

When medicine ignores nutrition entirely, and nutrient supplements are still complete unknowns, you have to wonder who the FDA is working for.

Medicine doesn't ignore nutrition, you just don't like the answers. And it shows on the research: e.g. does creatine help muscle building? No.[1] But cue some anecdote from someone where they also changed a dozen other things at the same time but are sure it was that. [1] https://www.unsw.edu.au/newsroom/news/2025/03/sports-supplem...

Creatine is probably the most well-studied nutritional supplement we have, and one of the most efficacious. You are presenting a single study to counter that. Not even a meta-analysis, but a single study of just 54 participants who did not exercise at all previously (from the study; "Apparently healthy individuals, with a body mass index of ≤30 kg/m2 and not meeting current physical activity guidelines of at least 150 min of moderate-intensity exercise were included. Individuals who undertook [resistance training] within the previous 12 months were excluded"). The general consensus is that it is absolutely helpful in muscle-building. See, for example [0] and [1]. Beware the man of one study. https://slatestarcodex.com/2014/12/12/beware-the-man-of-one-...

[0]: https://pmc.ncbi.nlm.nih.gov/articles/PMC12665265/ - Meta analysis results; "after intervention, the Cr group exhibited significant strength gains"

[1]: https://www.mdpi.com/2072-6643/17/17/2748 - "A total of 69 studies with 1937 participants were included for analysis. Creatine plus resistance training produced small but statistically significant improvements... when compared to the placebo."

Non blinded self experimentation is not a useful branch of empiricism.

I had an ME/CFS patient that had tried 100s of things and documented the effects thoroughly. She had a quite impressive list. Roughly 30% had had an effect to begin with, but the trend she observed was that it lasted for around a month at most. Placebo was her overall conclusion, but she occasionally got relief anyways so we both agreed that there was no harm in continuing. I'm sure several "peptides" is on her list by now.

There is nothing new under the sun, and fad cures for diffuse conditions have come and gone many times before. This is especially the case for conditions involving pain or tiredness, which are extremely sensitive to both placebo and nocebo.

What would be revolutionary would be 2-3 double blinded RCTs showing a lasting effect. Which would be great if someone did! But you have to actually bother to do it. And personally I would put money on the outcome being "no effect".

These peptides are already relatively cheap, here's one US domestic source: https://imgur.com/a/OXOkSdR

$120 for 10mg of reta is highway robbery.

Pretty sure the last time I bought some it was more like $10 for 10mg.

Clinical trials are not looking for fundamental mechanisms, they are there to ensure an effect is strong enough to say a product should be sold for that purpose. Otherwise you end up with snake oil salesmen. Because how can you be sure you are even injecting the thing the sellers claim it is?

I would encourage everyone interested in peptides to read about the state of medical science before the establishment of the Pure Food and Drug Act of 1906.

I'm glad we have GLP-1, and I don't think there are really major side effects. But they are ineffective outside clinical trial setting for treating obesity. It seems to be like treating alcoholism with disulfiram: it's a miracle in clinical trials but in the real world the patients just lower the doses or discontinue treatment after 1-2 years and go back to their old habits.

It is not ineffective outside of clinical trials. All the evidence says that people gain some weight back after they discontinue treatment - which is not a lack of efficacy. But they also usually gain back less then they lost. https://pmc.ncbi.nlm.nih.gov/articles/PMC12361690/

It's kind of two separate topics: 1. Whether patients can adhere to GLP1. 2. Whether discontinuation leads to weight regain.

Im sorry for your quality of life problems but calling doctors bad at statistics and then giving anecdotal evidence as proof has to start ringing some logical bells right? You dont even have to take our word. Use an LLM as judge. Paste your comment into chatgpt and see what it says.

The author is missing a massive segment of that gray market: people who buy FDA-approved weight loss drugs (e.g., semaglutide or tirzepatide) at 2–5% of the brand-name price. This route carries some risk, but there are ways to mitigate it, such as performing third-party testing. I assume most people who do this couldn't realistically afford the brand-name drug anyway, making this their only viable treatment.

I bought Semaglutide at 50c/mg and had it tested, it's the real deal. What's the normal price, $100/mg? My gf is in medicine so she had a friend test it through their work.

Test what, exactly? Purity? LPS contamination? They cant test for every last picogram of material in it. Did they test for viral contamination?

Even drug addicts heat up the thing they inject so theyre actually safer than you can ever be. Dont inject things from China into your blood!

I take a small issue with the claim that we don't test peptides. Some of us test them extensively before injecting. Granted, probably the same people who also understand how little science there is backing up most of the popular peptides today. I enjoy being able to buy my own GLP1s, however, at least those which have made it through phase III trials succesfully. As tempting as the claims are about things like BPC-15…

So you agree that this whole topic is in a sliding scale of lunacy, youre just on the saner side a bit?
