ILS Found Perfection & 20% off the Peptide Critic store until Sunday night 8/9/26.

🧪ILS Did It Again

Just when you thought the joke had run its course, ILS came back stronger.

This time they apparently found 100% pure retatrutide, which is incredible news for chemistry because it means the rest of the scientific community can finally pack it in and go home.

No more pesky trace impurities. No more rounding. No more real-world analytical nuance. Just pure, flawless, mathematically perfect greatness.

In other words: ILS is still doing ILS things.

Somewhere, a peptide chemist just looked at this report, slowly removed his safety glasses, and walked into the ocean.

ILS is just having too many problems. Whoever over there is making decisions doesn’t seem to be that smart… I won’t use them anymore. Cujo has a feeling they are going to burn out and fade away because of all their poor choices.

@Commander I have started filtering out vendors using ILS. But nowadays everyone is jumping around so many labs. I think only Peptidology's been consistently using Vanguard all along. I usually order from them with more confidence.

I wouldn’t necessarily rule out a vendor because they use iLS, but I don’t trust most vendors testing anyway…

@OldGuy True! A vendor showing a new lab COA on every new batch seems to be a in a hurry to get the batch out somehow than ensuring QC. Now that customers want testing, just a COA for a COA, regardless of authenticity of testing.

These vendors often have newer batches but at this point I've become skeptical about the freshness of vials vs quick COAs from questionable labs.

Peptidology batches are sometimes older, but they have been consistently using Vanguard and full testing panel even when it was not in vogue. That invokes trust! Not advertising Peptidology, not an affiliate either, but just pointing out clear differences I noted between them and others.
