If you understand the possible sides of deca and still want to use it go for it, Ive never been a big fan, but some love the shit. Couple things, drop the deca a few weeks before you come off the test, maybe three. This is always a good idea to try to let the majority of the deca clear before the test clears(actually, traces of deca stay in the system for up to 2 years!). This will also help you avoid killing ur libido, which is kinda a big deal. Another thing, your dosage of Sust is too low. Why r u using sustanon? thats old school shit bro. anymore, people use one test and get much better results. this is why; depending how ur sustanon is composed, ur getting small amounts of different tests(again, depending where you got it, sustanons levels of each test are different); the problem with this is all of the compounds are run on too low of a dosage to make the cycle worthwhile. This means that you should be running at least 750-1000mg / week. Also, because you have prop in there, you should ideally be shooting eod. Susutanon is the least effective injectible test, drop it and go with prop or enth, and end the deca at week12 if on for 15 with enth. If you use prop, drop the deca and find something else. Tren ace would be awesome with prop for a 10 or 12 weeker. |
