That was just from my limited experience using all. Those are not concrete opinions as I would need to research more. Moreover the doses we are using are significantly lower than the studies so that is another major factor. But sure the 1 time I tried Myo HMP (ex good sponsor) it done nothing. Literally not a thing... like I injected water. Folli I have used 2 sponsors and nothing great and for the price there are much better options. I was majorly disappointed with our folli. The one time I used ACE-031 it felt amazing. My strength sky rocketed and it was definitely not placebo. Adrol had been the best strength increaser I had used at that point and the ACE easily surpassed that with 1 vial. I think I used 3 vials for that run so 3mg rotated with folli each week. I want to try ACE again to see just how good it is.
