Weight gain ??

I have more than 15 cycles under my belt and have been on trt for 16 years.

I started a new cycle and 4th week in I'm 10lbs heavier but looking leaner but thicker.

Test C 600mg ew
Mast E 400mg ew
Primo 100mg biWeekly
Proviron 75mg ed

I don't feel much/any water retention.

I did not want to gain weight per se more to cut and look harder.

I've never used the last 3 compounds so wasn't expecting big weight gain.

Thoughts?
