I don't believe anyone's outright claimed they've been getting estrogen conversion due to increase in testosterone , I'm definitely sure no one has posted bloodwork on this board relation to Testruction use so even if they did claim this it would be anecdotal / speculative which is likely to be placebo. A couple of posters have mentioned itchy nips but frankly you cant infer anything from this. i dont believe Matt himself has made any such claim of test increases. i believe he said the MOA is that some substances can the sensitivity of androgen receptors. Butea Superba, one of the main ingredients, definitely has no/little evidence of boosting test in humans
I do agree with your main premise however about the state and lack of innovation in the 'test boosting' category. Note the inverted commas as virtually none can demonstrate their products actually boost test
