Phantom Doctrine

You may get lucky and hire, or rescue, and agent towards the end of the game who already has their stats above 140. If so, great - that makes it pretty easy! If, however, you want to engineer a Super Spy Squad with outrageous statistics using your Body Engineering Facility then the following sequence will get your agent's stats well over 140.

This Super Soldier Serum should net most agents in the game 4 Movement Points and 3 Action Points, as well as HP over 160. Not all agents are created equal - I like to focus on agents who have base statistics in the 60s, or ones with the loyalty perk. But, really, use who you like. A squad of these brutes trivializes combat even on hard mode.

It's also of note that a good majority of agents come already with drugs in their systems boosting their stats. You'll have to use the Remove feature into the Body Engineering Facility to get them back to square one prior to beginning the above chain as certain drugs cancel out others, or need to be used in specific sequences.

Here is a picture of my Theremin as an example of where his stats were at Level 10 out of 20 .

In chapter 7, I completed a random asassination mission. The agent I rescued had all stats over 140 by themselves. I then applied a random compound to them ensuring that the game registered this then cheevo unlocked. Saved so much time trying to figure out and obtain all the compounds needed to do this legit.
