well its a bit of an overkill thing to do really
what you want is a good anabolic and immune state during recovery. the lead up doesnt matter
some anabolics need time to kick in, so youd need to start them pre op
if something goes wrong though, you might find yourself in a catabolic state during recovery (recovery really takes about 10 weeks overall for proper tissue bonding...some people can take 6 months...depends on teh site, person, the cut bla bla bla)
not a huge need to do it, dont see why youre so concerned. is it really worth the drama to heal that little bit faster? if it was cutting a 2 month recovery down to 2 weeks then i see your point but its more like getting a 7 week recovery down to 5...if that
anyway, good luck
