I would recommend looking at 11-kt rather than 11-OXO - 11-OXO get's it's benefit from it's conversion to 11-kt...it's the pro hormone to 11-kt. 11-OXO needs to be run really high to get its benefits. 11-kt is going to deliver much more at a much lower dose.
If I remember correctly, most users run 11-OXO at nearly 1000mg to really see benefit. you can run 11-kt at 130-160mg and likely get more benefit.
It stacks incredibly well with Cardarine for a fat loss stack.
Two products available with 11-kt are Iron Legion XI-KT and Iconic Formulations Ultra Eleven.
