See our confidence rating for Core Peptides above, pulled live from our review database. Their community marks are strong and they've been around for years, but our rating leans on the depth of testing we can verify, which lands them in the middle. We recheck it as new batches get verified.
What they carry, and why it matters for you
Core leans toward the skin and cognitive side of the catalog. They stock GHK-Cu and AHK-Cu for the skin and hair research, Semax on the cognitive side, and Epithalon for longevity. The card below pulls their current per-mg pricing straight from our database, so what you see is always live today.
