Isn't 20mg the amount in all the AMS/Forerunner rapid disolve tabs and their liquid Mass Drops? I've seen several people say that those products, though not nearly as strong as the Andro Series, are decent for what they are. The claim is that absorbtion through oral mucosa is much higher and more effective/direct to the blood stream than going through the digestive tract.

On the other hand I don't think I would bother with LG Sciences pro-hormones, but I do like their GHenerate and M1D Black(esterfied DHEA) products.
