What is your previous cycling experience? Why only a 10 week cycle when using long esters? How often are you pinning the test and tren? Are you using an AI? What do you have in mind for PCT?
As above. No AI? No DA? Any HCG? Sounds like a poor cycle.
Why switch? If you fail to plan, you plan to fail. You should have had enough gear for 12 weeks plus your PCT. You start messing around with doses and switching to a blend, you're asking for problems.
