I dont know about HGH but he says he takes testosterone. Mark Sisson says he takes Testosterone in this article.
I get a few emails about Mark Sisson. People ask me how come his body changes so much. He looks like a runner in one shot and a bodybuilder in the other. I find that interesting as well. I do know that Mark takes and sells a LOT of supplements. On his blog he says he takes around 10 000% of the daily RDA for b12 in the form of his methylcobalamin supplement pills (primal defense he labels them). I know b12 is taken in supp form to aid with muscle mass in bodybuilder circles. Mark takes a lot of whey protein powder too (cos you cant get enough protein as a vegan so you need to eat meat AND buy Mark Sissons whey protein powders ;)
Here are some of the photos people have sent me that raise suspicion. Hey, just cos a 58 year old male does human growth hormone to market books to fat people telling em to stop doing cardio, stay away from fruit and eat bacon 6 times a day doesnt make em a bad person. Or does it? My question is how on earth does someone change body shape so quickly. From marathoner looking to bodybuilder looking? Ive showed these photos to friends of mine that take PED's and 2 of em said 'hey, can you get me his contacts?' lol!
Marathon runner body.
