>> ...but there seems to be this novel called black light that came a little while before MD came out. Long story short, there seems to be a theory that the Adam played in the game is in fact a clone of the original. <<

Wiki editor Aeratus did an in-depth analysis of this theory and all existing evidence in his blog post Is Adam Jensen a Clone in Mankind Divided? A Review of the Evidence.

By the way, the theory originates not from the Black Light novel, but from something found in the VersaLife vault in the Palisade Property Bank in Prague. (SPOILERS Reddit post with screenshots.)

>> basically, I just want the simple answer to this question: where did Adam get the experimental augs from? <<

After Adam's body was pulled from Panchaea by "an Illuminati-controlled recovery team", it was "secretly sent to a black site facility in the Baltic Sea for identification and study" (source: official MD timeline). It is implied that Orlov operated on Adam (either the original Adam or the clone body) at this facility and installed the new augs. Then Adam was transferred to the WHO facility in Alaska for recovery, and the subsequent events are covered by Black Light.
