Is it a problem switching gear midcycle? For example, If u wanted to run a 12 week cycle of test. Can u run 10 ml test E250 for first half, and 10 ml andropen275 for second half? Reason I ask is a buddy of mine wants to run a similiar cycle to what im currently running and has a bottle of test E on hand. But our source can only get andropen275. I dont see this a problem, but just want to clarify.
