Thanks Brundel and Studhorse for your answers. Yes, planning a minimun of 12 weeks. Maybe more if results are on point.
Next monday start the epic bulk phase, diet dialed, new old school hardcore gym that i love (been on a commercial like USA's 24 hour fitness, here in Spain, absolutely disgusting for say something soft and polite)
Thinking about also buy something extra: 1 andro, 4 andro would fit ok with FD and Vector, or MK 677, or a natty test boster.
Note that I'm 43 y.o. my test levels are on the low side, no bloodwork done but i don't feel like 20 years ago....
