We're not here to suggest drugs for you to try, and threads like this often lead to substance ID's, which is prohibited.
Truly "legal" drugs sold as MDMA substitutes typically contain caffeine and other common stimulants that are absolutely nothing like MDMA.
Research chemicals are not legal for consumption, but many threads reviews these as being similar or identical to MDMA. It's a personal experience/opinion thing, and you can find many trip reports on erowid and bluelight that will give you all sorts of well explained experiences.
