Im doing 10 weeks of sust at 750 with letrozole, Do I have to start the letrozole at day one OR would it be more cost effective if I started at the 2nd week?
Id rather not waste it and use more towards the end.
Sustanon isn't really known for aromatizing, but with a dose like that it might not be a bad idea to start between day 1 and day 14 after your first injection.
If I was going to frontload anything, then I would definetely start the anti-Es that day.
