adipo and NYC are supposed to be the same thing (though the later produced bottles of adipo tend to fall short of NYC in potency.. guess with the raw materials running low they shorted the batches.)
clen or ECA are good alternatives to switch too.. you should rotate more frequently though.. ideally every 2-3 weeks
the old MD6 ruled...it also had ALA, which the others don't. I stockpiled several bottles when they stopped making it...just finished off the last one two weeks ago
