An independent column
Catalog depth, lab documentation, format innovation, payment flexibility, shipping. Written by Devon Reyes — unsponsored, US-focused, occasionally exhaustive.
Eight US-facing catalogs reviewed. Only one carries a pre-filled, calibrated pen at all — let alone fourteen of them. A note on why the format matters and what the rest of the field is doing instead.
Kits, packs, blends, and 10× bulk vials are not the same thing. A pass through eight vendors looking at which actually curate goal-themed multi-peptide protocols — and which just resell volume.
The single most-requested peptide in the catalog. Which US suppliers offer it in more than one format, which keep the same documentation across all of them, and what that means for protocol design.
