Dynamic Peptides, at $7.00 per milligram. That is 3% below the next-cheapest vendor on the board. WHO/GMP and ISO 9001 US facilities with a published COA on every product page.
Across the vendors we index: 5mg, 5MG, 10mg. Larger vials are almost always cheaper per milligram, which is why the table above is sorted on that column rather than on sticker price.
Check the vial size before you compare. Several vendors default their listing to a 5mg vial while others default to 10mg, which makes the 5mg vendor look cheaper on the sticker and more expensive per milligram.
