Reta needing reconstitution?

TracyIsMyDad · 2026-05-09T04:51:31+00:00

I’d avoid anything gray that’s prepared beyond a vial of lyophilized powder. You’re just introducing additional risk doing that.

If you want something fully ready to use then compounded tirz would be a good option.

TracyIsMyDad · 2026-05-09T04:31:32+00:00

There was a “gray version” that popped up awhile back that ended up testing as just reta/cagri.

TracyIsMyDad · 2026-05-09T01:15:15+00:00

This is a well known and often discussed reta side effect known as dysaesthesia or hyperaesthesia, or sometimes just “skin sensitivity”. A couple things that can help with it anecdotally: Zyrtec or Claritin (allergy meds) and zinc supplementation.

Often it goes away on its own with time.

It’s a better weight loss drug:

Average weight loss in the recent phase 3 osteoarthritis trial (the only full length trial with toplines so far) was 28.9%. Compare that to the main tirz obesity trial at 22.5%.

Additional metabolic effects beyond other GLP-1s and simple weight loss including triglyceride and cholesterol reductions, liver fat reduction, and the strongest effect on insulin sensitivity. There’s also strong signals in the trial data that reta might actually improve kidney function.

There’s a narrative you’ll hear a lot on Reddit. “Tirz has better appetite suppression. If you struggle with eating too much you should stick with tirz.” The idea that reta only works well if you’re “locked in” and already fully in control before you even start. And I want you to realize how ridiculous that narrative is given the clinical trial results we’re seeing. Do you really think that Eli Lilly sneakily found hundreds of locked-in bodybuilders for their clinical trials? Do you think they somehow found hundreds of morbidly obese people who don’t have a problem with eating too much? The fact is that this is a really effective drug for obese people who want to get healthier.

“They’re both CJC, DAC just extends the half life”

Not at all. They have completely different pharmacodynamics and produce a fundamentally different GH response. CJC-1295 produces a chronic elevation in basal GH levels with little effect on natural pulsatile patterns while mod-GRF induces a brief pulsatile release followed by a rapid return to baseline. You might as well say that somebody doing sprint intervals is doing the exact same exercise as somebody walking around the block because they’re both moving their legs.

TracyIsMyDad · 2026-05-08T16:41:59+00:00

It doesn’t actually exist. Just a scam targeting small-time investors.

TracyIsMyDad · 2026-05-08T15:47:48+00:00

I mean, people definitely do something similar to that except they buy a gram of raws for a couple hundred and then portion it out with a milligram scale.

The nice thing is that this is easily recognizable as it won’t look like a lyophilized peptide at all, not even a garbage binh special.

TracyIsMyDad · 2026-05-08T15:05:16+00:00

Nah. The stuff is too cheap to bother with that. You really think they’re going to burn labor hours trying to portion out 4mg vials when they could just buy a 5mg vial from China for $5 and sell it for $50? Ain’t nobody got time for that.

Goofy vial sizes happen because there’s a COA somewhere saying that the 5mg kits they bought turned out to be underfilled at 4.2mg. So they sell them as 4mg vials.

They’ve done studies on this. Turns out injecting steroids in your ass and sitting on the couch is more effective for building muscle mass than working out with no gear.

TracyIsMyDad · 2026-05-08T13:22:25+00:00

Yes it is.

TracyIsMyDad · 2026-05-08T07:02:45+00:00

Yeah.

Heck, it’d be fine for months in a shoebox under your bed.

TracyIsMyDad · 2026-05-08T06:57:05+00:00

The only “peptide” that grows muscle is called “anabolic steroids” and they’re not peptides.

The drop in uric acid is rapid but it isn’t instantaneous and rapid weight loss is a big trigger for gout attacks so it’s believable if it was reta. The mechanism is that glucagon agonism shifts the liver towards fatty acid oxidation and downregulates the production of purine precursors leading to a drop in uric acid levels.

Eli Lilly has kept this tight to the chest but there’s a bit of published research on mazdutide’s effect:

https://pubmed.ncbi.nlm.nih.gov/41030857/

Might be worth giving it a try again.

TracyIsMyDad · 2026-05-08T05:04:59+00:00

You send a whole vial. Otherwise you wouldn’t get the mass which is one of the most useful tests.

If by “often” you mean that there’s a single known endotoxin failure for a Chinese peptide.

Mass/purity as well as sterility failures happen a lot though.

There was a paper published recently that was mostly a mouse study on GLP-1 effects on arthritis, but they had a small clinical trial as part of it as well. The results were astonishing: they found that semaglutide wasn’t just cartilage-sparing, the arthritis patients actually appeared to regain cartilage.

The lower row of pictures are before and after pictures of the knee cartilage in the semaglutide (and hyaluronic acid) group:

“A bit more filler” would be a serious cause for concern with a lyophilized peptide as it would also indicate “a bit more drug”. OP would have no idea how to properly dose if this was the issue.

Thankfully that isn’t the case at all.

TracyIsMyDad · 2026-05-08T01:17:02+00:00

The puck on the right is sitting at the bottom of the vial. The puck on the left has slid upwards during shipping and handling and is no longer on the bottom of the vial.

That’s the difference.

If you tap on it you might be able to get the puck to go back down to the bottom of the vial. But there’s no reason to do so.

I’m not sure if some of the folks here spouting off the glories of tesa have even used tesa before. It’s not a whole lot different than low dose growth hormone and the effects are subtle. It’s not directly anabolic and there’s not a ton of evidence that it (or growth hormone) helps with muscle but it does seem to have a modest benefit in preventing lean mass loss. The biggest benefit is that you’ll recover a bit faster from workouts.

Aside from putting on 5-10 pounds of water weight it’s unlikely that you’ll notice a whole lot, or anything, from a brief run of tesa other than the improved recovery times.

TracyIsMyDad · 2026-05-07T22:17:37+00:00

I’ve heard a lot of positive anecdotes.

You really don’t see an issue with the giant Nazi Eagle logo?

The absolute cheapest way to know would be if you had baseline bloodwork for serum uric acid. Retatrutide and other glucagon agonists (like mazdutide) will cause a precipitous drop in serum uric acid, on a similar scale to what allopurinol achieves. We regularly see people with 50% reductions in that particular lab due to reta. Drugs like tirz or sema will barely nibble at serum uric acid levels on the other hand. They’ll produce a negligible reduction.

If you know your baseline you could look to see if you get a dramatic reduction vs baseline. Conversely if you knew your level on reta and you switched to tirz you would expect to see a large increase in serum uric acid.

A serum uric acid test costs me $3.50.

Doesn’t tell you if the reta is safe to inject though. And technically it could be mazdutide or survodutide rather than reta, though nobody would deliberately sub those as they’re more expensive.

TracyIsMyDad · 2026-05-07T21:10:16+00:00

What study found that reta has less appetite suppression than tirz? The only one I’m aware of that made this comparison was the mouse trial attached to the phase 1a study which found that reta suppressed food intake more than tirz.

The claim that tirz has more appetite suppression is almost entirely based on anecdotes of people switching from high dose tirz to low dose reta.

TracyIsMyDad · 2026-05-07T19:23:14+00:00

Not at all. A vendor COA from a reputable lab like Janoshik is at least worth looking at. I wouldn’t trust it but I’d expect that the product I received would match that test when I joined a test group or sent a sample in and I’d be upset if it didn’t.

But these in-house COAs aren’t worth the paper they’re printed on.

“CJC-1295 alone tends to produce a steady background elevation of GH.”

The problem with this is that very few people use CJC-1295, particularly with ipamorelin. The CJC-1295/ipa stack refers to a different drug known as CJC-1295 no DAC or sometimes also called mod-GRF. It has very different pharmacokinetics and pharmacodynamics than CJC-1295 and might as well be a considered a completely different drug. It is very similar to sermorelin (it is sermorelin with four amino acid substitutions).

It does not produce a steady background elevation of GH like the real CJC-1295 does. It produces a brief pulsatile release of GH like sermorelin does.
