I have tried both 7oh and Pseudo. I started with 7oh, the recommended 1/4 dose and felt really nice, warm feeling lasted around 5-6 hours. Nice euphoria feeling. Next day I tried 1/2, and for me it was too much, not sure how to describe it.. "too warm feeling"?? hence i recommend start 1/4 or even less for newbies. Wheras pseudo, is different also took 1/4, but it was less euphoria and more pain relief and warm feeling.
