alt Hacker NewsPeptides: where to begin?
Comments
I tried retatrutide for 10 weeks, here are my results: Before: 5'7, ~182lb
Bench 1rm: 315
Squat: 5x10 225
Deadlift: 5x5 315
After: same height lol, 154lb
Bench 1rm: 285
Squat: 5x10 205
Deadlift: 5x5 275
Suffered some anhedonia towards the end but that went away ~1wk after stopping. Overall pretty good, not any side effects. Definitely fixed my food craving problem. I didn't have a high intake of protein during the 10 weeks, so I suspect thats why I lost muscle mass :/
I'm not inclined to be a guinea pig for these. I suspect maybe later in my child's life they will have been proven long-term safe (or not). I'll be old or dead at that point. I'm really wary of putting anything not known to be standard food or medicine into my body.
Lowe has a point, but the FDA has painted itself into a corner by (a) forcing up the costs and the various bureaucratic demands associated with clinical trials, (b) allowing drug advertising , but then forcing those comical "may cause death" disclaimers, both of which have become totally ubiquitous, and (c) inconsistently following its own rules, and in some cases flouting its own rules.
At this point, broscience is considered no less valid than actual clinical trials, and the FDA should blame itself for this. Not "human nature being what it is in this fallen world" in a sort of general or abstract sense.
Another point I could raise is that telemedicine has turned the entire prescription system into nothing more than a parasitic middleman/gatekeeper.
FDA reform is very badly necessary. That ought to come before harsher enforcement, and I think that much of the populace already intuitively understands this.
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 know a couple of people that should know better (phds in biosciences but now doing corporate management) taking expensive weird Chinese peptides that would probably be better off if they did some cardio a few days per week and ate better.
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-157 and such ... no thanks, that is past my comfort level a good bit.
It seems we are treating Peptides like drugs here. It's my opinion that amino acids regardless of how they are chained do not belong under and stricter regulation than food given I eat peptides every day from my food. Then again I do not believe in the concept of prescription drugs. Everything with a NDC code should be at the grocery store and I should be able to stock up on it without permission especially given how fragile global shipping is these days. Drugs risks do not enter into the picture given the fact I can buy ammonia and bleach along with a myriad of other dangerous compounds. Worse, I could crush up apple seeds from the veggie isle. One can also make just about anything using fourth thieves vinegar. Maybe put expensive high demand things like cocaine behind locked glass along with the underwear and condoms.
As a side note more dangerous than any drug is stopping a prescription drug cold turkey. Watch what happens when global trade to/from China and India are cut off for a year. Attitudes will change.
I really enjoyed having to wait 30 seconds for Cloudflare to let me into this website.
> My patient is refusing a drug studied in 170,000 people because of side effects that a 124,000-person analysis just confirmed do not exist — while injecting a compound studied in 14 humans, from unregulated sources, based on the recommendation of someone who profits from selling it. She’s probably not the only one. And those using it believe they are “doing their own research.”
Ok, and? At worst you waste a couple hundred dollars and deem the alternative therapy not worth it and go back to your doctor but I know dozens of people at my gym that used BPC 157 and TB 500 that fixed their chronic tendon/joint issues within weeks of starting the therapy that physios couldn't fix for years.
> a patient who is discontinuing her statin therapy - very inadvisably, given the clinical presentation described - but is enthusiastic about “BPC-157”
This feels new. I thought the methylene-blue-for-cancer types continued their medicine while taking other things as extras.
Personally, I've swung over to the laissez-faire side of medicine. At the end of the day, if you're an adult, it's your body. You should be given the chance to educate yourself. But if you want to inject yourself with a prion, like, go for it. Maybe you won't fuck up your own research.
(Marketing should be tightly regulated, possibly banned.)
> For a chemist, “peptide” has a pretty clear definition: any relatively short chain of amino acids, and when they get longer we go ahead and call them “proteins”, although the dividing line is a matter of personal opinion.
So, it is not just chemist but molecular biologist too. And the above is also not entirely correct. Yes, the author refers to size as threshold, before something is called a "protein". But the term protein has additional meanings that a peptide does not automatically have. For instance, a protein typically has a specific 3D conformation. It may be "sticky" after degradation or unfolding, but for the most part a protein is something with a 3D structure. A peptide does not necessarily imply the same. A protein may also have several polypeptide chains - insulin is a simple example for that: https://en.wikipedia.org/wiki/Insulin#Structure (A and B chain)
> So the number of different possible peptides is just ridiculously huge.
That's no surprise either - that's due to the code used. You add to the code, so of course length plays a role, as does the variety. There is a DNA->aminoacid mapping. The first has four possibilities per slot; the latter 20 (or more if you include e. g. selenocystein or pyrrolysine; and you have various post-translational modifications too, so you have more variety per slot).
> For comparison, it has been about ten trillion seconds since Homo sapiens emerged as a separate species.
The whole species concept is IMO outdated. It was created before people knew that DNA codes for the complexity in pretty much any species (excluding RNA viruses but they have reverse transcriptase, at the least some viruses, so ultimately RNA->DNA).
> The other one (by Sarah Hood) relates all this to RFJ Jr.’s advocacy. The flip side of “the government shouldn’t be able to force me to vaccinate my kids” is “I should have the right to take whatever medicines I want to without the government getting in my way”.
I don't see why that would be questionable. Would people do as Trump tells them to do? I would not. If you see Trump as a lobbyist, how many private interests may his government have? If they have a commercial interest then their statements may be biased.
> You don’t have an LC/MS or an NMR machine in your garage, so you can’t be sure what it is you’re really injecting
Right, so the whole system depends on trust. This is already a problem because you have to trust not only the government but ALL who were involved in scientific publishing. There were lies told in science too: https://en.wikipedia.org/wiki/Retraction_in_academic_publish...
I read the article but didn't get the tl;dr about peptides. What are they and what are they used for?
With India getting generic GLP-1s, the tech to "print" peptides will probably see costs fall off a cliff, so we're probably only looking at the tip of the iceberg with the amount of damages the reddit biohacker bros will accomplish. Men especially are feeling a lot more lonely and image-conscious and there are peptides people claim make them taller[1] or muscular[2].

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 knowing why they work. I think people are just going to circumvent the fundamentalist and chase after whatever works.
I owe my health to early adoption of experimental peptides, I have life long ME/CFS and there is no known treatment for this nor is there any on the horizon. At least they finally have a diagnostic test and know it's not psychosomatic but I could have told them that from day 1. Most doctors are not researchers and have little understanding on statistics instead preferring to rely on discrete classifications and simple decision tress. As someone with hEDS from TNXB I am a walking bag of symptoms and yet not a single doctor could figure it out. I had to research it myself which involved post-doc level textbooks and research journals. I came across the work done by Prof. Khavinson (USSR) and it did appear to me that peptides were incredibly under-explored. Given the poor quality of life with ME/CFS I was willing to take serious risks so previous trials were helpful to give an idea on dosing and lethality, I went through most of the research peptides one by one. I actually waited on semaglutide a bit because I suspected there was a small minority who would have hyper sensitivity and I both expected that to appear in the data, which it did, and I expected to have hypersensitivity, which I did. Others who were less careful ended up with pretty bad gastroenteritis. Semaglutide has been the most effective and with it and a few others I am largely able to lead a normal life. I was getting gray market from the US but now I get it direct from China.
