Okay, so, lithium is used to treat bipolar. Metformin is being tested to treat lithium weight gain. Modafinil is sometimes used for treatment resistant depression. And escitalopram is an anti-depressant. All of that, plus the hormones (which some doctors think might help folks with depression), makes me think that the author has a health issue and his biohacking success is actually just reflective of him getting better. I can't see how he could convince a doctor to prescribe these meds otherwise.
tl;dr: money <i>does</i> buy happiness after all.<p>Like, it's great that rich CEOs get to burn all this money and have all these necessary connections for their "biohacking", but very few of us have that kind of money. It'd be nice to get some info on doing this sort of thing on a budget (and preferably without being able to bribe - er, "persuade" - a doctor into writing a bunch of prescriptions).
