Androgel does work at raising test levels. The problem is that most docs who prescribe Androgel do NOT prescribe anything to compensate for the possible negative effects.
Increased estrogen, increased DHT, and most importantly, decreased LH and FSH levels.
It is also widely accepted that Androgels absorption ability can vary from patient to patient.
IMO the best TRT protocol includes test injects, AI, and HCG.
