Alot of MDMA I have ordered recently from multiple vendors, whether it be white or brown/tan has had a lot more of the "speedy" effects of classic MDMA and not as much of the "loved up" effects/feelings, why could this be?
I'll bite. Given you've tried product from multiple sources and find the effects to be similar in nature, we can largely discount the drug itself being the source of the difference in subjective experience. That leaves set and setting, and the current configuration of your synapses.
I don't know you and your chemical history, frequency of use, nor social environ, so I can't do anything but wildly speculate about the way it's affecting you, and how that differs from other experiences.
I can say this: In a prior stage of life I was involved in the production of MDMA for recreational purposes. The prevailing ethos in my circles was one of shared creation and experimentation, and financial involvement was frowned upon. Those on the periphery of the circle got to taste a great variety of compounds without any money changing hands, and without ever knowing where it came from, which I mention to give a frame of reference.
Dosed with MDMA.HCl from the very same batch, produced under optimal conditions and at a purity seldom seen where I am these days, people would ascribe different properties to the product as their state of mind and their neurochemical state changed with circumstance, and whatever else they'd been taking.
I had people telling me that this batch was smacky and mellow while the last batch was speedy and uptight, and another batch was trippy, when unbeknownst to the describer the MDMA was all from the same batch. We'd made the stuff they were taking, and were educated and equipped to say that what they'd described as multiple different batches was a product entirely identical across doses.
It appears that with a fixed quality and purity people's experience of the drug will change as their neurochemistry changes, and as their life circumstances changed.
I appreciate that this isn't really an answer, but it's the information I have. Try to remember what it was you did when the feeling was "loved up", and see if you can recreate the circumstances. My experience suggests that this will allow you to attain the same state of mind and feelings as you once did, presuming you haven't burned your receptors or neuromodulated yourself into a state that precludes such delightful states.
