我刚从一家经常光顾的供应商那里买了一套Reta20试剂盒——我复检了第一瓶，发现里面的液体是浑浊的，这种情况难免发生，我当时也没太在意，就又复检了第二瓶，结果还是浑浊的。我用的是一瓶全新的Hospira细菌培养液。为了确保不是细菌培养液的问题，我又复检了一瓶旧的，结果清澈透明。我已经联系了供应商并附上了照片，希望他们能妥善处理，但即使他们解决了，我现在也用完了Reta20，估计下个月我的体重就会达到300磅（约136公斤）。
呼吸道浑浊（我的血液酒精浓度很好）

你刚拿到一套试剂盒，已经复溶了两瓶加上一瓶旧的，现在Reta用完了。
你不是还有8瓶新的加上那瓶已经溶解的旧药瓶吗？

我看到有人推荐用AA水来帮助澄清浑浊的Reta。
30毫升的Hospira对我来说很难在合理的时间内用完，而且它相对便宜。
如果我的存货不够用，我会先从1毫升开始尝试，直到找到澄清的（或不澄清的）为止。
听起来你还有时间等他们的回复。

Not for Reta. It's too fragile and adding AA can lead to clumping and aggregation, or exactly this situation. BAC saline is also not recommended. If your source is a known good one and you know it's tests well, I guess you could filter it, which I do anyway. If I had a kit or 5 though, I'd toss it and try another vial.haveadaytoday said:

Interesting. My vendor recommended AA for my cloudy reta. The next vial was clear so I never bothered seeing if it would work. They also recommended BAC saline as an additional solution.
If your BAC water has Sodium Chloride, it will result in precipitation of Reta and looks like the ones in you imageambot88 said:
With Tirz there is no problem
AA is the go-to for every cloudy vial, it seems. Very few peptides need it, with good BAC, and it's been shown to breakdown the amino bonds in Reta. BAC saline, while not as damaging, has been shown to degrade Reta quickly. A BAC like Hospira is all you need.haveadaytoday said:

Crazy thing is I used Hospira and got a cloudy vial. Tried the next one with random BAC that came with a different order and it worked fine.Chili777 said:

NP. Could just be that vial. It happens.haveadaytoday said:Crazy thing is I used Hospira and got a cloudy vial. Tried the next one with random BAC that came with a different order and it worked fine.

Not sure where you got yours but saw this posted in the ERP tg. I’d probably start with some extra bac to see what happens.
“Folks, I chatted with Louise and got the lowdown on the factory issues. It’s residual TFA salts in the finishing process as expected. Please read below.
After confirming exactly what the issue was, I found a much better option for most.
Although AA (Acetic Acid) could work, it is way less than ideal as it can cause a severe sting on injection.
Note: if you already added BAC, you may need to transfer to a larger sterile vial for the rescue.
THE HIDDEN SALT PROBLEM: WHY YOUR RETA IS CLOUDY
The ERP factory source is admitting to a salt content issue in recent batches of Retatrutide. If your vial is cloudy after reconstitution, it isn't a bad peptide—it is a chemistry failure in the finishing process.
1. The Salt Gap: Why It Passes Every Test
Standard tests don't catch this because they aren't looking for residual solvent or salt content.
• The Purity Test: Measures if the peptide sequence is correct. It doesn’t care about the salts surrounding it.
• The Sterility Test: Checks for bacteria. Residual acid (TFA) isn't a living thing, so it won’t grow in a lab dish.
• The Reality: During manufacturing, a harsh acid called TFA is used. If the lab rushes the "wash" phase, the peptide arrives heavy with acidic salts. You can have a 99% pure peptide that is 30% acid by weight.
2. The Retatrutide Cliff
Every peptide has a specific pH "cliff" (pH 5.1 for Reta) where the molecules lose their magnetic charge. Instead of repelling each other, they clump together and crash out of the liquid. Since BAC water is naturally acidic, it pushes these high-acid vials right over that cliff.
3. The Rescue Methods
Method A: Adding More BAC Water
Adding another 1mL–2mL can sometimes nudge the pH enough to clear a "barely" cloudy vial.
• Pros: Easiest; no extra supplies.
• Cons: Low success rate. You’re adding more acidic liquid to an acidic problem.
Method B: The "Acid Force" (Acetic Acid / AA)
This moves the pH down significantly to force the peptide to dissolve in an ultra-acidic state.
• Pros: Dirt cheap; shelf-stable for years.
• Cons: The "Sting Factor." It can feel like a bee sting at the site and may cause tissue irritation.
Method C: The "Alkaline Nudge" (Sodium Bicarbonate)
Adding a tiny drop of a strong base (8.4% SB) to neutralize the acid.
• Pros: Sting-free; very effective.
• Cons: High risk of "over-shooting" the pH and damaging the peptide. Expensive and short shelf life.
Method D: 1X PBS Buffer (The Winner)
Phosphate-Buffered Saline pulls the pH to exactly 7.4 and locks it there.
• Pros: Foolproof and self-limiting. It mimics the body’s natural environment for a smooth injection.
• Cons: Requires a separate lab-grade buffer.
4. Minimizing the AA Sting
If you use the vendor-provided AA kit, follow these comfort protocols:
• Post-Clearance Dilution: Once the vial is clear, add 0.5mL–1.0mL of Sterile Water to dilute the acid.
• The Room Temp Rule: Never inject cold acid. Let the syringe reach room temperature first.
• The Slow Flow: Use a 31G needle and push the plunger as slowly as possible (10–15 seconds).
• Topical Prep: Use Lidocaine cream 20 minutes before.
5. Recommendation: The Rescue Filter
When buying PBS, look for 0.1 or 0.2 micron sterile-filtered solution. This ensures no contaminants are introduced during your rescue.
6. Instructions & Storage
1. The Rescue: Draw 0.2mL to 0.5mL of sterile 1X PBS and add it to the cloudy vial. Gently swirl. The cloud should vanish in minutes.
2. Note: Recalculate your syringe units since your total volume is now higher!
3. Storage: Keep opened PBS in the fridge. It stays viable for 3–6 months if you use sterile techniques.
4. Peptide Stability: Once cleared with PBS, the peptide is actually more stable than in acidic BAC and lasts 30–60 days in the fridge.

That sure sounds like a great candidate for this issue, and it says it's from ERPs factory source which means there may be more out there from other vendors. PBS seems like the only real answer if it's still going to be used. If it was me, I'd want either a credit or a replacement of equal weight from another batch.
adding more water didn't help and all that other stuff is way over my willingness level. Vendor has agreed to reship so I'm satisfied with how they're handling it but super interested if more people have had this problem. RT20 Purple cap.
Lots more. ERP TG is filled with them, but the vendor is doing a reship there too, so good. I have kits of R20s coming myself. Won't know until they get here. The issue is being reported with vials from Swiss now, too. So far it's R10s and R20s with a red cap. The ERP batch has blue tops, so that may be a poor indicator and shows that multiple finishers may have received this product.

Phosphate buffered saline is cheaper than BAC water, if a bit harder to find.
I think there are going to be a lot more vendors affected by this. The TFA salts issue at ERP is at the manufacturer level. There aren't many manufacturers compared to finishers. I've heard between 3 and 5 of them in CN. This could just be the tip of the iceberg.Camlbacker said:
I don't frequent the other vendor TGs too much, but in my testing group I'm hearing that other providers are having the same kind of issues that suggest exactly what you are. I managed to dodge the bullet in advance by getting the R30, which hasn't had any reported problems. The TFA salts issue is the first real product related issue I think I've heard about with ERP other than the guy who bought the kits of Melanotan 2 and Mots-C, promptly got the the lids to the kits mixed up and subsequently shot 5mgs of MT2. Not ERP's fault of course, and fortunately he was ok.Chili777 said:
