Well I have friends under 6'(natural) and meet very lean goals over 200lb's and you're only 22yrs...They use
Synthetek.com and/or
PureSupplementPowders.com products all day long...So I think you could meet your goal of 'beefing' up naturally....But a first cycle could be as simple as 200-300mg's of test/week including pct. Another could be Test(500mg's) and Eq(400-600mg's) per week with pct. Many should prob. start simple with blood work to see how they react.
Too many variables to list here...
