Probably not a bad idea to take the HCG. I stopped TRT a few years ago do to issues with E2. My levels went back to exactly where they were pretty TRT. I never experienced that super low effect many guys fear when stopping cold turkey. With the HCG and the fact it's 'only' a month, you should ok. At the 30 day point for me, I felt way less energy and slept worse then when on T, but 30 days wasn't enough for me to really feel my worst symptom of low T...the dreaded Brain Fog!!!
