The Dermacrine has more than enough DHEA to be effective… probably even too much for some guys. Remember, DHEA in a transdermal is about 10x more effective than oral because it’s taken up by the skin so much more efficiently.
Redsamuai is right though, you won’t have anything to worry about with only 4 weeks on Dermacrine, especially if you’re using Sustain afterwards…. But even without it you would be fine.
