Newbie Long Winded Question

Hi,

I’ve been trying to decide if I should maybe try going down the route of trying something additional to help me build muscle but don’t know where to start.

I have had half arsed attempts at building muscle over the years, but admittedly my nutrition was never where it should have been. But even then my strength would increase but my muscle size would not, I’d get annoyed and end up giving up after lots of hard work in the gym.

I’m not naturally thin or tall (5’7”) and can pack weight on easily.

Since March I’ve been doing a body recomp, 500 cal deficit, exact macros to preserve muscle and lose fat.

I’ve have lost 3 stone and nearly at the point where I adjust my calories to maintenance for a month then go into a slight calorie surplus to build muscle.

During this recomp I’ve got stronger but again little to no gains in muscle size, so I’m wondering what the best step for me would be supplement wise to compliment the bulk phase?

I’m 44 so ordered a testosterone test to identify what my levels are to see if this is an issue.

Any help would be appreciated
