Who's actually the best peptide vendor in 2026?

Lots of vendor talk, lots of marketing. Curious where people are actually buying from this year and why.

Specifically curious about: COA transparency (batch-linked or generic?), shipping reliability, refund policy when something fails QC, and how support handles edge cases.

Not asking for vendor names so much as the criteria you actually use to pick. The rankings page on this site is a good start — looking for the lived experience version.

My personal short list: batch-linked third-party COA, refund policy that names purity thresholds, ≥18 months of community history. Two of the top three on the rankings page meet all three.

I rotate between two top-ranked vendors specifically so I have ongoing comparison data. Locking into one vendor permanently is how people miss quality drift.

Underrated: how the vendor handles a problem. Test them before ordering with a non-trivial question. Response quality is a great proxy for what happens when something goes wrong.
