Neither vendor wins across the board, which is the main takeaway. Labsourced is cheaper on 8 of the 33 shared compounds and Ion Peptides on 21. 4 of the 33 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: Labsourced lists around 42 compounds we track versus 51 at Ion Peptides. Outside the 33 overlap, only one of them will stock what you need.
