I have read many times before that deca ran BY ITSELF even did not create deca dick, some members claim to not have a problem on deca and maybe that is how it works for you. I personally dont recommend trying it your self the way the OP is suggesting but if you want to test the waters run it closer to equal doses of test first. My experience was that at 750mg/w test and 750mg/w deca, my time frame for getting off greatly increased. what used to take 10 minutes now took 40 minutes and I could tell during intercourse that I could easily loose erection and feeling was dulled. I started that cycle at 750/500 and then later increased to 750/750 and a week or more the problems started, they cleared about the same time frame as they came.

anyone reading this post- if you take deca run it with testosterone- and nolvadex and clomid for p.c.t at a minimum for four weeks!!!, also use either caber/ prami or bromo!!! while on cycle with and ai for your test wich is either adex or aromasin!!!!!!!
