I have used Hubei, Spa and BTG Var and they are all extremely potent. I have also used several of the "underground" var's and NOTHING holds a candle to these 3.
You must understand, Hubei BUYS THEIR OXANDROLONE FROM SPA. So the Ox is Pharmaceutical quality.
SPA and Hubei is sort of like Sustanon and Omnadren. Both the same compound EXCEPT for the price.
Definitely go with the Hubei. You WILL NOT be dissapointed.
