Pick the strength and how much you need. We work out the grams of 2-((4-(Dimethylamino)phenyl)diazenyl)benzoic Acid and what they cost at the cheapest store we track.
Weigh it out, dissolve it in less water than you need, then top up to the full amount.
How we compare: each store's own price, turned into US dollars at European Central Bank rates of 2026-10-29, then divided by the pack size. Shipping and tax are not included.
