I havent read anything yet about puffiness in people yet although it definately can happen. This product converts to test and other hormones so it can definately happen. Also there is more then 4mgs of ATD in the product, the ATD was also in the old version of M1D which we have since removed and now use Androsterone as our anti e along with another anti e.
M1D is a great product and we have had a bunch of great feedback on it, give it a try i bet you will be happy you did.
If you have anymore questions dont hesitate to ask bro.
