2 months is is a good amount of time to pct and reset or cruise before another blast.
Here my stance on adding another compound.
If your first cycle went amazing and you had no issues and everything was perfect then why not?
In your case i see you had a bit of trouble with adex dosage on 300mg a week. This concerns me for a couple reasons 1) 300mg/week is not a lot im suprised you even neesed adex. 2) i see you had hcg in there. Im guessing this was the preserve the nuts while on cycle? Hcg aromotizes in the nuts so adex doesnt counter act the aromitization.
My suggestion is unless the hcg is absolutely necessary then drop it. Run a second test only cycle and see if you cant get it perfect before adding another compound. If you rewlly want to add another compound for your second cycle make it a oral compound that doesn’t aromotize and add it the last 4 weeks that way you get tue first 8-12 weeks to try and get the test situation dialied in better this time
It is possible that yes when a lot of weight is gained rapidly the body needs a bit of adjustment time.
Altho um willing to bet the joint issue is because you were suffering from low E2 taking that adex in such a small. Amount of test when the real E2 symptoms were coming from that hcg which the adex wasnt helping at all
