CBL-514 is an investigational injectable medication that could prove both safe and effective when it comes to trimming stubborn fat deposits under the skin of the abdomen.
Is Tesa Out of the Game? CBL-514 Steps In as the New Tesa

I'd really like to see some articles or links on this. Yeah, I'm aware Google is a thing, but what I'm more interested in is what you've personally come across, rather than Google's chilly robot-brain algorithm, haha.
That said, I'm not convinced Tesa/Egrifta is on its way out. From what you're saying, CBL-514 targets subcutaneous fat, whereas Tesa goes after visceral fat with full force. Whether pairing them carries any serious risks, I can't say, but if you did stack them, you'd probably end up looking like a Ghoul straight out of Fallout, I'd bet!

What do you mean when you say it's safe? The 3 things that concern me before I'd start Tesa are edema, plus cortisol and prolactin going up.
Once the FDA gets around to banning every peptide, they're really going to have their work cut out for them, because my guess is it'll have to happen compound by compound. A blanket ban covering every compound that exists or was ever synthesized doesn't seem like something they can pull off. At least I hope not. What science needs is thousands, possibly millions, of brand new peptides, each altered just enough in its structure to count as its own compound while producing comparable effects.
All it should take is a handful of tech bro scientists armed with AI to start churning out millions of fresh peptides daily and send those FDA luddites back into their cave.

Can you actually purchase CBL-514 at this point? To be clear, I'm talking about the grey market, not the big pharma version.

I only began looking into it once I came across this post. Still, my hunch is that even if it isn't, that situation won't last long. What really grabs my attention is the safety profile, assuming it turns out to be comparable to the peptides in the 'morelin' class.
"It is a proprietary small-molecule drug currently in Phase 3 clinical trials and owned exclusively by Caliway Biopharmaceuticals, a publicly traded company based in Taiwan (TWSE: 6919)"
That lines up well enough with what we've been hearing

I would need to dig around for the references, so for now you will just have to trust me on this, but the product is reportedly a proprietary blend built mainly around Curcumin and resveratrol (possibly at a 4:1 ratio). No published formula is out there, and that is likely the reason it has not shown up broadly on the grey market. At least 1 animal study hints that it may also do something for visceral and hepatic fat along with certain metabolic parameters. What grabbed my attention the most, though — and again, I would have to dig this up — was 1 animal study indicating that weight regain after GLP-1 was reduced when CBL-514 was used at the same time. So it does appear to work and be fairly safe for subcutaneous fat, while possibly having other uses too.
It is intriguing. Compared with some of the deoxyxcholate-based formulas, it also seems less harsh. After searching a bit, I have not located the exact formula, or anyone producing it, anywhere.

Skimming it, this looks like something aimed at localised fat rather than visceral fat, which makes it a different animal from tesa.
Per the paper, CBL-514 from Caliway Biopharmaceuticals in New Taipei City, Taiwan is a small-molecule injected lipolytic: in nonclinical work it drives adipocyte apoptosis and shrinks subcutaneous fat in a targeted way, with no reports of skin necrosis, ulceration, nerve damage or systemic side effects.

It also claims HPLC testing, yet the report link goes nowhere.

I'm not the one composing these letters — I'm simply the messenger. To put it another way, I know nothing at all about any of these businesses; a quick search is how I came across them.
And as someone else already pointed out, once you look at certain studies, the vial sizes together with the prices are nearly comical.

Honestly, that's kind of amusing — the studies dosed 600mg/day while each vial holds only 20mg, meaning you'd need 30 vials, likely quite pricey ones, just to cover a single day's dose.
My curiosity got piqued when I noticed SANA being sold on ebay. It works by activating futile creatine cycling to burn off energy, similar to a mitochondrial uncoupling agent such as bam15 or DNP, except through a novel and distinct mechanism. It even has phase 1 human trials, which puts it ahead of a large share of peptides. That said, the doses were 600mg/day and 5 grams runs about $100 usd ( on ebay ), so purely on cost grounds it isn't really workable ( $100 for 8 days worth ) — that is, if you're willing to take something backed only by phase 1 data. It's nearly as expensive as non grey GLP's. Even so, it's probably a safer bet than bam15 and unquestionably safer than DNP. Oddly enough, despite its track record, they are seriously working on a prodrug form of DNP that gets converted into DNP in the liver, so its effects stay more localised, the doses reaching the body overall are far lower, and presumably the odds of killing you drop as well.

This isn't a GH peptide in any way. It works entirely differently. What it is: a small molecule that instructs fat cells to undergo programmed cell death. Administration is local — think a set of injections spread over the abdomen, for instance.

Producing and distributing CBL-514 won't be a simple task. Building it is far more demanding than putting together a basic short peptide, or even one of medium length. The raw materials themselves aren't hard to get—curcumin and trans-resveratrol can both be sourced without much trouble. The tricky part is the synthesis route that turns those starting materials into the small molecule; it appears quite involved. On top of that, the patent doesn't make it clear whether the compound can be stabilized into a powder form. It's possible that it would need to be shipped as an injectable liquid under tightly controlled conditions. Any vendor claiming to have it in stock today would raise serious doubts for me.
Based on what I've read so far, which isn't much, I'm not sold on this one. Even if grey managed to pull it off, and given the challenges mentioned that seems like a stretch, the concept itself is fine. But I'll stay with the proven options for fat loss, mostly GLPs, until there's substantial long-term safety data showing the molecule doesn't harm other healthy cells or cause unexpected issues. And seriously, if a grey version is slightly off, what happens then? Best case is it's just bunk, worst case is maybe destroying the wrong cells?!
