Honestly, I've been lurking on Peptidesgreyhouse.com for a bit and the info there seems pretty decent for a research-focused site. One weird thing is how spotty some of the user reviews are—like, some folks rave about purity and others say shipping took forever.
From what I gather, it’s mostly solid for getting your hands on less mainstream peptides like Epithalon or LL-37, which don’t always have the best availability elsewhere. Not gonna lie, I’d still cross-check batch certificates or whatever else you can find before trusting 100%, but for basic lab research, it looks alright.
Anyone else done actual in vitro testing with their peptides? Curious if the stability holds up beyond just the paperwork.
