I know neither is good. but which would be worth alcohol 5 pints beer per day for a year or 3 months of 200mg testosterone per week for muscle growth?

Who says 5 pints of beer per day promoting muscle growth?

You are correct in that neither is good. Testosterone is worse and beer will not promote muscle growth. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health!
