No COA

[UghItsStupidNIHateIT]

Has anyone here ever used a peptide without a COA? Like you didn’t test it either, just used what they sent you and hoped for the best? Or used a peptide from a supplier that had COAs that were good for many of their products but didn’t have one for the specific dose you ordered? I’m specifically asking about Tirzepatide.

"Anyone" "ever" are enormous qualifying words. Of course people have.

I give zero credence to vendor supplied COA.

Before I discovered this forum, I purchased Reta and didn't know if it had a COA. After doing some research, I found it in a smaller format. I haven't had any problems, but if you want to be truly confident, you need to analyze them yourself. You can never be sure that the vials are consistent with the COA provided.

I just had two vials fail testing. I will never use anything that does not have a current COA.

I don't do GB, telegram or discord I just email. I looked at all the COA from a vendor I had chosen, not looking at anything but lot# and batch# and they looked organized. I don't even test anything for my own use. I ordered two kits Triz and Reta. My wife and tried they for three weeks with good results and we are still alive. I then purchased a large order of Triz and Reta to last my wife and I at max dose for 5 years all had the same batch#s This method may not work for everyone but it worked for me. Call me lucky, stupid or dumb I dont care.

What failed? Purity, fill or something else.

I'm sure a vast majority of us have, at least once, if not more.

My first ever pep was reta, and I got it from my ugl source. Of course it didn't come with anything and I now suspect it was tirz because I had crazy appetite suppression that I was not able to replicate with real, tested reta.

same thing that happened to me with the first order I placed, I had much stronger suppression

What did they fail for?

 

[spanky2026]

What did they fail for?

And more importantly, who supplied them?

From XTP on this site. Tirz had no detectable amount of Tirz in it. KLOW was only GHK-CU. There will be a complete review tonight.

I would find a diffent vender. Get one that you can trust and stick with them.

Yup, with tirz and a few other things. My most recent kit of tirz turned out to be a little spicy, which I realized when both my husband and I had increased appetite suppression after a couple weeks on it. Not a big deal, just had to decrease my dose a little.

Do you do your own testing or just kind of hope for the best?

 

[FartfulCodger]

I have. I'm now in the practice of giving myself a tiny dose the day before the full dose, even for peptides that have good COAs. I'm most concerned about endotoxins. The thought is that I'll get mildly sick instead of super sick, and I can stop in my tracks before taking a large dose.

What is “ugl”

Honestly yes and this applies to testing 3+ months ago too, if the last test for your wished product is from 2025, I would say you doing the same and hoping for the best

 

[sheilarae74]

It depends on your risk level. My first 3 vials were without a COA and they were my best ones.

Not surprised. I got my last 20mg reta from them and it wasn't as good as my first vendor.

I've done group testing, group buys with testing, and bought from vendors with a track record of complaints that suits me. Buying in larger quantities and ahead of time lets others test/use/complain about issues online before I have to partake in the more recent deliveries. Group buy testing methodology isn't very rigorous either... the average person is well out of their depth.

In general there are batch variance and no one is holding them to actually using batch number methodology.
