How much does testosterone impact muscle growth?

[randomman154]

Hello, turns out I have a severe vitamin D, magnesium and zinc deficiency. Because of this, at the ripe age of 23, my testosterone is at 450. Will raising my testosterone affect my muscle growth? I’ve been lifting for years with zero progress as you can see from my previous posts. Does anyone have any experience hopping on TRT with test in the 400s, how did that impact your muscle growth and your body in general?

Cheers guys
