IMO best option is SERM+ little bit of AI- lot of people are doing mistake and overdose SERMS, as sometime with too high dose you get opposite effect.
Now, fact is that raising testosterone with SERM or AI dont yield same benefits as with natural or even exogenous test, and also TT:E and TT:SHBG ratio is important- and also (IMO) testosterone effect on wellbeing is bit overrated.
