Bro, god damn, slow down haha. No, do not increase tamox, where are you getting your information from ... For a mild cycle you do not need so much serms, I mean, you don't even need more for a stronger cycle, rather, the duration of the pct lenghtens.
My PCT's were usually 20/20/10/10 tamox. Those were your run of the mill 500mg test + an oral cycle. Maybe you can do 40mg for the first week.
Zuclomiphene has a long half life so it will stay with you for a while, I'm saying you wont be better in a days time.
The problem with clomid in pct is because 1. you have crashed androgens, 2. you had high androgens just a minute ago and now they are crashed so you are going through a strong rebound, and 3. zuclomiphene being a potent estrogen, making things suicidal.
Taking clomid during a cycle or while being natty is something completely different as your androgens are high but during pct it's a completely different story.
Recovery will happen even without SERMs yes, but much slower and thus more painful.
How long after your last injection (of what compound?) did you start the serms? It takes 5 weeks for test E to clear your system and then you can start pct (depending on the dosage you can start it earlier). I'm asking because if 5 weeks didn't yet pass, then keep tamox at a higher dose and then drop.
