if this were the case, (you wouldn't be able to tell anyways, the actual difference in testosterone is like 6 mg or something small like that, wheres Billy when you need him) then QV would be underdosing.
People often consider cypionate as superior to enanthate. I think it has to do with American doctors only prescribing cypionate and not enanthate. After knowing this, and considering that cypionate is more expensive, people also think that they get better results, because they got what they paid for, or whatever their reasons may be.
I have always used enanthate with great success but will try cypionate just for fun. Dont knock it till you try it eh?
