You have to think about the short and long term affects my friend......

Your career will be for around 10 years but you must look beyond that

Anyway we wouldn't want you to learn the hard way so my advice is research and train hard for a few more years your test levels will be peaked

Test only is advisable at 25yrs old and typically body fat under 16% with 2 years solid training

And finally your calorific input will determine weight gained or lost !!
