AI? What does that stand for and which drugs are in that category? HRT for 12 years. Haven't messed with higher doses since I was 45, nothing crazy. Most was 750 test and tren 100/eod. No sides except a bb sized lump under my right nipple while on tren long gone. Going to do 12 weeks 600-750 test c along with 6 weeks tren ace at 100 eod. Also my joints hurt at age 57. Add small dose of deca maybe. Thoughts please.
