Some added notes to BenTrens cycle, he hasn't done bloods, he doesn't understand what damage high E2 can cause apart from what obvious to primary senses like growing tits or no erections, started with only 1 vial of test, no AI no PCT, is 18, didn't have money to buy another vial of test to continue the cycle... Not an excellent candidate to take advice from
Longer cycles are more difficult to recover from. Think this through either you take some PCT meds (no need for AI during PCT) with you. You should have planned this and in your case I'd postpone the vacation, always have tickets you can cancel. Or cut the cycle short at 10 weeks, get 2 weeks off, then 4 weeks PCT up until vacation. If you decide for a longer cycle then IMO just inject 100mg per week after week 12 to keep test levels normal then PCT, though again recovery is more difficult the longer the cycle.
