I think the best solution would be for you to get a plat membership and do some research. You'll learn a lotta shit on here...do this before using aas.
you can do it for PCT. But, you need to stop the deca 2 weeks before you stop your testosterone. Clears it out of the system, and then PCT starts 2 weeks after your last sust injection. (using an oral in these 2 weeks is acceptable to continue gains righ tinto PCT) Sust carrys a long ester, so you need to let it clear before trying to stimulate your natural production of test.
