similar testing process to marquis reagent, will turn purple in the presence of indoles such as LSD
if a few people are interested i will buy the reagents and make some to sell much cheaper than EZ, probably £5ish plus postage for as many tests as you'll need.

marquis is simpler, it's 95 parts 98% sulphuric acid with 5 parts formaldehyde. you can control the rate of colour change with methanol. formaldehyde solution usualually comes with a methanol stabiliser anyway so it will probably contain it.
