As a professor at Purdue University he led a team to investigate and synthesise chemical analogues of MDMA which are non-neurotoxic. Some of these are MDAI, MDAT, MDA, 6-APB and 5-IAI. At the moment MDAI and 6-APB are extremely popular in the study chemical market, MDAI is frequently referred to as 'Sparkle' and 6-APB as 'Benzo Fury'. The following points need to be considered when choosing a supplier to acquire MDAI from:

Trustworthy Retailer - These chemicals are now widely accessible from dozens of on-line retailers but sadly you can't trust them all. Several of these shops are trying to get rid of old stock of banned substances such as Mephedrone and Naphyrone (NRG-1). In this case you must expect that any web site selling MDAI fairly low cost (£10-£14 per gram) probably aren't even selling MDAI at all. They are just in a hurry to shift old products so try to get some other shoppers experiences of a retailer that you want to use. Also if you search on Google then the highest ranking results will be greatest as they should be performing well to have money to be there meaning they can probably afford high high quality products.
