How to read this

Neither vendor wins across the board, which is the main takeaway. Ion Peptides is cheaper on 17 of the 30 shared compounds and Hydro Research on 11. 2 of the 30 shared compounds are priced identically at both vendors, so for those it comes down to shipping speed and stock rather than price. If you buy a single compound, the table above is the answer. If you are placing one larger order to save on shipping, the vendor that wins your two or three highest-volume compounds usually nets out ahead.

Catalog breadth matters too: Ion Peptides lists around 51 compounds we track versus 40 at Hydro Research. Outside the 30 overlap, only one of them will stock what you need.
