AR-R's stuff on the banner is all good. You can depend on the quality of any of there chems.
When you say if you stop both the test and deca today, you are missing an important point. If you stop the deca at the same time you stop the test the test will clear the body quicker than the Deca. Since the Deca completely suppresses the bodies own production of test this will leave you in a state of basically zero Test which will not be fun. By stopping the Deca and running the test for another few weeks to a month you will ensure that the Deca has had a chance to clear before stopping the test this will give your PCT drugs a lot easier job to do.
