to look good, eat healthy all year round, don't get too fat (over 12% bf), workout year round, not to heavy or too often (2x/week is ok). Come spring, IF diet with 500mg test/week, 250iu HCG 2x/week, 20mg tamoxifen after 12 weeks for 4 weeks and you're going to stay healthy and look great on the beach. No sides whatsoever.
If family history of any kind of cancer, don't do it.
