Test, Clen, and T3 I'd be eating calorie surplus based on LBM still and let the extra muscle from the test burn more calories. 20mcg's of clen isn't much, I usually start at 50mcg's and work up to 100mcg's split in 2 through the day by the 3rd rotation of 2wks on/off.
The Test requires extra calories, the clen is burning extra calories and the T3 is burning even more. You need more food, more frequently to see the results you want.
Mentally I think you need to approach this with the goal of putting on mass and the changes in body composition alone will yield the results you are looking for with the clen/t3 ontop of test. You are approaching this with the mindset of cutting and calorie restriction and you are hindering your own progress. More food, more frequently and keep it clean. Lift heavy and do cardio and you will morph.
