I study ester like 10 years ago and decided that the long esters had to have a peak somewhere and since I wanted a consistent amount of test is my system I choose to mainly use prop. Sustanon seem to sound like a logical way to go if it works the people think. Sustanon or Blends have test with multiple esters. I am assuming they are all brewed together to the same melting point. With that assumption the only logical conclusion I could come to is that the esters combine creating a new and unknown half life. It is hard for me to wrap my mind around Test Prop releasing in the first 2 days then Decanoate release the next 2 days now comes Cyp for the next 3 days and now take another shot. Now maybe just maybe (if it would hold) you brew them separately then mixed maybe but still. Just wondering if anyone can explain.
