It's not a new hypothesis, and it seems as though many men see their best results during transitions. However, it doesn't seem to be as simple as adding daily peaks and valleys to the sex hormones. If that were the case then everyone would be on daily testosterone propionate doing great. I've been experimenting with propionate for a year, and I did have great results during the transition from testosterone enanthate. But I've been unable to repeat the really good period, and other effects during the last year, good or bad, are too subtle to specifically attribute to the propionate.
