The best results are by combining an over the counter Aromatase Inhibitor like PES Erase or Triazole with a test booster like HCGgenerate and Vitrex. Also brief cycles with DAA mixed with an AI work well. There are several legit blood work showing test levels being boosted in the high range from this. Not supraphysiological levels like 500 mg of test, but enough to make some decent natty progress. I have have done several of these cycles and have gotten a harder, fuller look. I'm 51 and on these cycles, libido is great, no hair loss . Don't have any need for HRT yet, even though I cycled juice in the 80's and early 90's. The only reason I don't juice now is that I have no interest in suppressing my hormonal output. I tend to believe , for health reasons, that the body responds better on the cellular level to your own testosterone than with synthetic test. I also believe the body prefers it's own GH rather than artificial sources, which is why cycles of gh Peptide 2 and Ipamorelin at moderate doses can be beneficial. In other words, I prefer to enhance my own bodies secretion of anabolic hormones rather than replace..and thereby suppress my own production. I'm able to maintain a fairly hard 200 pounds at 5'9". To be extremely lean, i'd have to go below about 180 pounds.
