I solved the mystery!!!
finally, after researching, its time to put an end to this crap
the REAL hygetropins are INDEED the 8iu tops, the pinwheel ones are COUNTERFIT (they DO have gh in them)... so they are both technically real, but the 8iu tops are the "brand" hygetropin, as if they were nike shoes, and the pinwheel tops are the knock offs; HOWEVER, there are OLD PINWHEEL tops still running around, that ARE 100% legit, non counterfits but were produced a while back... Zhongzhan biopharm is now currently producing RIPTROPINS to end this Hyge counterfit BS, which are basically like the original PINWHEEL hyges, so techncally any NEW pinwheel hyges being produced are COUNTERFIT...so that solves that...so for the best get either Riptropin or Hyge 8iu tops... game over, your all welcome
