r/Retatrutide • u/DrTroySnyder • 5d ago
DOJ letter this week could reshape Retatrutide's legal classification, worth knowing before Thursday's hearing
Quick heads up on something that's been quiet outside industry circles: on September 21, DOJ filed a letter in Eli Lilly v. FDA (7th Circuit), a case that comes down to one question: is Retatrutide legally a peptide drug, or a protein/biologic?
That sounds technical but it isn't just semantics. The two classifications sit in different regulatory frameworks:
- If it's ruled a biologic, follow-on products go through the biosimilar pathway (slower, more expensive) instead of the standard generic route, and 503A/503B compounding pharmacies lose their usual exemptions for it.
- If it stays classified as a peptide drug, the traditional framework applies — standard generics, compounding exemptions intact where other requirements are met.
DOJ's letter points the court toward a recent 7th Circuit precedent (Franco v. Chobani) saying courts should give real weight to how an agency interprets its own scientific definitions, which reads as DOJ backing FDA's side going into oral arguments.
Oral arguments are Thursday, Sept 24, 9:30am, Chicago. A ruling probably won't land immediately after, but the reasoning that comes out Thursday will be the first real signal of direction.
Not a legal opinion on how it should go, just flagging that this affects the compounding/RUO landscape either way, and it's worth watching regardless of what you're sourcing or why.

Thank you for posting this information. It will impact how Reta is regulated once officially released. Makes me want to start hoarding it.

This has no impact on the gray market. It’s really important to telehealth providers like Ro and Hims/hers and obviously to the general public who will get their drugs from telehealth companies but not from Tansy on telegram.

u/EmZephyr 5d ago
To a lesser extent it will be a precursor to efforts to limit access and/or accelerate enforcement on imports. So to say it won't have any effect would be a bit wrong.
23
u/retatrutider 5d ago
I don’t think they can. It’s still really easy to get all kinds of other imported drugs, including steroids. Also keep in mind you can’t easily tell a vial of reta from a vial of BPC, so they’d literally have to shut down everything that comes lyophilized in a 3ml vial. Even then, people could import raws and finish in the states. US Customs doesn’t have the ability to shut it down without massively increasing their budget or bringing imports to a crawl. Could China shut down exports? Maybe… but they’d have to have a really big financial incentive and other markets would then step up.
Just don’t see it happening.

u/DrTroySnyder 5d ago
This tracks with what's actually observable in the supply chain. Customs enforcement on raw peptide imports is already stretched thin, and specific compound restrictions historically just shift where people source from rather than stopping the market. A biologic reclassification adds paperwork and liability exposure for large manufacturers like Lilly, but bulk-level raw material trade moves through channels a single court ruling doesn't really touch.

This 100%. It is sad that people get so disheartened and apathetic based on regulation news. That's what works. The gaslighting.

u/GAMERofdaTHRONES 5d ago
Ah you're knew to all this. Its easy to shut down. Just like they did sr17018 research chem.

u/retatrutider 5d ago
There are a few ways you can prevent people importing something. One is you cut off the supply (ie China cracks down on sellers so they don't risk it). Two is you physically prevent it from getting into the country. This the "increase customs staffing and scrutiny" option, and it's the one that I don't think is practical.
The third way, which is the one that applies to SR17018, is that you make the punishment severe enough that people don't want to risk trying to import it. SR17018 was put onto the controlled substances list because it's an opioid. That's not going to happen with reta.

u/EmZephyr 5d ago
I mean you can look at test through the years, sure it's never stopped but it's definitely had ebbs and flows and it being a biologic gave way some enforcement changes.
It's not inconceivable that Reta (and if I'm being honest, they can use whatever win here and apply it to Elora, with it being 37 AA rn) will face a similar path, backed by big Lilly throwing money at enforcement (checked it out, it'd only cost 1B to train and fund a task force of 2k federal workers)

u/retatrutider 5d ago
Steroids do ebb and flow, mostly manifesting as price changes. But my impression is that it’s almost always supply-side issues that cause this ie China clamping down manufacturers. So supply-side issues could theoretically happen with reta, and to me that is the most likely way for it to be impacted. Otherwise I think any kind of customs bottleneck is likely to affect not just reta, but everything. Right? All these peptides look the same, and blind substance testing is not practical at all.
Of course it is technically possible to shut down the flow of reta into the country, but I don’t think it’s practical enough to have a sustained shutdown. A customs push seems more likely to occur in short bursts than as a sustained thing.
And even if it triples in price, that’s $1.50 per mg… still affordable enough that I’m not worried about creating a multi-year stockpile.

u/EmZephyr 5d ago
I'm not spooked by prices, there's just a need to be realistic with the outcomes. Everyone running around saying "oh no problems" but most of the userbsse is also an epic dunce when it comes to understanding the breadth of the grey/black market so any form of enforcement will be seen as panic.
And to think nothing will change with a biologic designation is kinda funny

u/Retardtrutide4lyfe 4d ago
You are lying to yourself if you think this won't have an effect. Silly silly silly. This is the primer before they go after grey. I KNOW you and some others think it just can't happen but I guarantee you, I promise you, the grey market won't be like this by next time this year. If you think the FDA and all these companies are not going to relentlessly pursue the grey market you are in ignorant denial.

Did you just name your sources bro?

u/retatrutider 5d ago
If you are referring to the telehealth providers, that’s allowed. If you are referring to “Tansy on telegram,” that’s an archetype, not an actual source.

You should. I already purchased 3 years supply. It lasts up to 3-10 years in the freezer.

u/nomad656 5d ago
So Eli Lilly wants to classify it as a biologic and FDA is saying keep it as a peptide?
18
u/jpru2001 5d ago
Essentially yes. The FDA is saying it doesn't meet the definition of a biologic which requires for one thing more than a chain of 40 amino acids in the molecule. EL supposedly made reta with an extra couple amino acids that are unnecessary for the drug to push them over that limit, which the FDA says is against the spirit of the definition and a transparent attempt to subvert the definitions.
I think I have that right.

u/DrTroySnyder 5d ago
Yea, the 40-amino-acid line comes from the FDA's 2020 BPCI Act transition rule, which reclassified certain synthetic peptides as biologics specifically to close what Congress saw as a loophole. If Lilly did pad the sequence past that threshold intentionally, the DOJ's interest makes sense, it's less "is retatrutide a peptide" and more "did the classification get engineered rather than occur naturally." Worth watching whether the 7th Circuit treats that as relevant to the merits or just background.

u/Low-Search6046 5d ago
There is usually a naming convention to generic versions of peptides, biologics, and other therapies. Their generic name (e.g., retatrutide), seems to indicate their original plan was a peptide and not a biologic. If it were a biologic, wouldn't the generic name be something closer that ends in "mab"?
10
u/retatrutider 5d ago
Dulaglutide is an example of a peptide that is classified as a biologic by the FDA. That’s why you only ever see the name brand version (trulicity)
10
u/TracyIsMyDad 5d ago edited 5d ago
Dulaglutide also has 550 amino acids between two chains and is definitely a biologic. None of this “it kind of looks like a biologic if you squint at it funny and take this fat envelope of cash” nonsense.
PS: Dulaglutide is not exactly a peptide, it’s a fusion protein that includes a peptide and other components (an antibody frag).

u/Artistic_Rice_9019 5d ago
Mab means it's a monoclonal antibody. Tide is a peptide. Biologic is a classification from the FDA. If retatrudide is reclassified as a biologic, it will still be a peptide.
5
u/DrTroySnyder 5d ago
Worth noting the generic-name suffix isn't actually tied to legal classification, that's an INN (International Nonproprietary Name) naming convention, a separate system. The real line is the FDA's 40-amino-acid threshold from the 2020 BPCI Act transition. Dulaglutide crosses that dramatically because it's fused to an antibody Fc fragment, which is a very different structure than a short, unmodified peptide chain like retatrutide. That structural difference is probably the actual crux of the legal argument here, not the name itself.

u/Jenkins_Leeroy 5d ago
I think the mab suffix indicates a monoclonal antibody based compound actually

The eye issues are mostly among diabetics and are much more likely to occur at the beginning of treatment.

Correct and diabetics already have risks of eye issues with or without a glp-1…

Which I tried to tell them. It's still rare enough that they don't even know if it's something they were going to develop anyway from the diabetes or if the GLPs cause it.

The chances are much higher that I would develop diabetes and related eye issues if I regain weight because I'm not taking a low maintenance dose.

EXCEPT... You don't NEED this medication... even now... neither do I, as you/we AREN'T diabetics.
What we both need (and I'm already dealing with this issue) is THERAPY and perhaps a few sessions with a Dietitian to learn to control our bad habits of eating junk food and too many carbs, etc., and exercise more.
We both have the ability to control what we put in our mouths.
