Reach out to them for sure.

They use dynamic QR codes so stuff can get mixed up but it's definitely not great.

Trust me when I say you don't want anything to do with the toilet water. Or the 30 ml ampules of genetek.

This was a while ago but I remember it. There is a COA.

Check out the vendor directory we started adding EU, UK https://peptidecritic.com/vendor-directory?region=uk
Buttons on the vendor page

I'll see if I can detect the region and have the site auto-display the one you're searching in.

We'll keep adding more as they apply, but suggestions are welcome from the community as well.

If noise is the issue tirz is king. Titrate to max would be my vote. Ive run both. Glucagon increased my rats hunger

Using a few known labs, one questionable lab and one very questionable lab for testing.

They ship to uk now?

Cant speak to uk customs but i have access to every big chinese reseller...and i just end up sending nexaph money instead. Its the easy button for me.

That's a top value, the vendor with the lowest price and more than 4 stars. We were testing this in the last few weeks and just rolled it out live to everyone yesterday. The labs they use were not factored in the top value spot on those pages at this time.

@andreasreinerszallis We tested the dual chambers, and all the ones we received the bac water wasn't bac water. At this time we wouldn't trust any of the dual chamber cartridges on the market.

@member-gvhtt These pens don't come apart again after you click in the cartridge, which means you throw them out after the cartridge is empty. Our other pen allow you to put in a new cartridge.

Research-use products are intended for laboratory research only, not for human or veterinary use.

@ogsteve so far yes

Also the intitial question. I did the same test with a similar sensor a while back. I saw 2 degree swings in the vault we used to sell and 4-5 degrees in the hydrapeak.

The swings arent going to ruin your stuff over a few years but I just opted for -20 deep freezers that need to be manually defrosted every few years.

I have a few thousand vials on ice. I use the sensor below in two freezers at two locations. It emails me if there is a temperature fluctuation out of a range i set. It's a free service. I have wifi and internet on a ups system and the sensor as well. Its good for about 6 hours and in that time i would know if power is out by a temp shift.

I had a freezer fail and this told me otherwise i would have never known.

https://link.amazon/B0fWD8KWu

they have factory seconds that look horrible but test fine and recon fine. 160 a kit i think. Ive run it.

@AGResearch I'm not going to bully you for the units comments (dilution math is what matters) but Trevor is not a doctor. He lost his license in california as a chiropractor. He also cheats in competitions.

Also a 50/20 blend on ghk/kpv is what I use. 2.5mg/1mg seems to work for this rat.

and most of these blends dont have tb500 they have tb4 but nobody seems to realize this.

enclo made me a food monster on 12mg of tirz.

@denti you could always double it....

@justinlaughlin Justin, switching labs doesn’t answer what we asked three weeks ago. You said you only published results that matched your supplier’s COAs. Did any disagree? What happened to those reports and batches? Is that still your policy?

And where are the batch-specific endotoxin and sterility reports? Its 2026. Why would anyone buy from you when we know of dozens of vendors that do more testing than you? Your published testing covers identity, mass and purity. Repeating “99.5% purity” (freedoms specialty) doesn’t answer either of those questions.

As for Max, I accepted when he offered blind testing. He then insisted I tell him what I was sending, so I didn’t bother.

And yes, I find your animated background hard to look at. You’re allowed to choose that design, and I’m allowed to dislike it. And you are listed. Just not how you would like.

The warning is accurate and based on your own statements; calling it “damaging” doesn’t make it false.

You’ve written plenty about my tone. The questions about your testing are still sitting there.

I did update the warning but I can't erase the past.
