Looks like he is trying to put on a little mass, or at the very least recomp by raising endogenous test levels. DHEA for the conversion and ATD to ensure that pathway to test. Somewhat comparable, albeit simplistic, to Methyl 1-D (conceptually, though this is not to say Methyl 1-D is as simple as this by any means). Again, I would add something that at least competes for reductase inhibition to reduce chances of elevated DHT levels.
