Ok as far as the Gspots go....the originals came out last summer and they were an MDMA/MDA mix. they had the ".G" on them. They were flatter and more wafer like than the current incarnations....rediculously strong....three sent me to outerspace.
The later versions of the ".G" were more barrel shaped....but with much more MDA than MDMA in them, if they had any MDMA in them, i didnt feel much....what i did feel was a heavy MDA dose.
the NEWEST versions are the "G." versions and i have no experience with them, but reports on PR suggest they are MDMA...but still strong.
Either way this press has A LOT of credibility right now, ".G" or "G." aside.
