Sus is a mix of short and long ester test. There is no need for any acclimation period off/on your TRT. You’re still running the test. E2 sides are more easily managed when taking either a short or long ester but gets complicated when you are running a blend like Sus. You can do it… IMO C or E are more ideal.
Summary… no you don’t take your normal TRT dose. Just blast the higher test of your choosing. Also IMO, a 250mg/wk blast is barely a blast but again its your call. When you get off cycle you just go back to your TRT. No PCT required.
