That would be one HUGE advantage of using Phlojel, but NOT with 1-test. Otherwise, we're talking about "the fire down below" in a bad way. I didn't bring this up in my discussion of transdermals because, well, most people wouldn't be terribly interested in maximizing the efficiency of transdermals to that extent. So, 3-alpha, 4-AD, 4-oht, and the others if so desired, nordiol, 14add, etc. -- these would all be great candidates for this application, 3-alpha in particular.
From the study you linked to, it seems clear that you would be best served by a lower concentration compounding, 3ml of 3% delivered way more anabolic effect than 1ml at 10%. This is obvious, the more transdermal you apply, the better the penetration will be.
Of course, with penetration enhancers like d-limoline and octyl salicylate added to Phlojel Ultra, penetration would be already improved quite a bit. I am not sure that DMSO + scrotal application is a good idea, but then again, I can't say.
