Hey, welcome to bluelight.
Id reccomend picking up a set of reagents. Using a few different ones, you should be able to narrow down what your mdma is.
Alternately you can send in a sample to a drug checking service, where they will use analytical methods such as GC/MS to identify what is in your "not molly". These services often have a fee, though there are a few free ones for some countries. Here is a list of drug checking services:

We don't allow "what drug is this?" threads, because nobody can give advice beyond speculation, and that can lead to people taking dangerous drugs and getting hurt. Since you aren't asking about the identity of a drug that you have just acquired and plan on taking, I will leave this thread open to talk about the broader phenomenon. (though mods who main basic drug discussion may disagree and close this thread).
Do you have any reports of the effects of this drug? Duration is one of the best things to pin down a drug, as the subjective high can vary and be harder to communicate.
Also, we don't tend to use SWIM here, because it doesn't provide protection in legal cases, and it clutters up threads. It's ok to admit that it is you here.
