So essentially one should only add a test booster if they're concerned with libido?
there are other benefits to test boosters, but it's not going to do nearly as much as a SERM!
example: nettle root (included in AX/DTP/DTH) will help unbind test. but, if you have low test then you don't really have test to unbind.
L-dopa (in DTH/DTP) helps with libido and HGH production, but that won't do anything for you natty test levels anyways.
etc...
PCT has the potential to leave you feeling pretty crappy...PCT Blues! having some supps in there to improve your mood/libido isn't nec a bad thing, but it's prob not going to make much of a diff in your test levesl.
