The only real problem with deca besides the need to cease it a little sooner than the test to aid in recovery, is the prolactin problem.
Bromo, and especially caber will deal with this with ease.
Problem is, most people can not acquire, or can not afford to use them on cycle.
Most people depend on research chems, and liquid caber has a bad reputation for a very legitimate reason.
I do believe we have found an effective substitute for deca in our friend tren. But tren has more side effects, is somewhat of a nastier disposition overall, and has some other minor issues associated with its usage.
Appetite problems associated with tren, in particular, may limit its use in place of deca.
