run your tren from week 2, at least give the sust a chance to build up a little bit. Run the tren week 2-9 inclusive.

You can add the var but I'd lower the dose and run it 6 weeks at least.

I'd probably stop the sust at week 12. It might make recovery easier but unlikely. You results will have probably slowed to a crawl by then. Also, 15 weeks plus nearly 3 wait before PCT starts and 6 weeks PCT and you'd be looking at best part of 24 weeks (6 months) off cycle if you follow the basic rule of time on = time off.
