I recently started a 10 week cycle of 1cc Test and .5cc Deca once a week. Nothing crazy... Ive continued using my Fish Oil, Multivitamin, vitamin D 6000 iu daily, and ZMA before bed. Im a big of Dr Jim Stoppani and use all his products. The Pre Jym, Post Jym, and Pro Jym Protein Powder and products I listed above. I was using all this stuff before I started the cycle, and Im following the same diet. Ever since I started 2 weeks ago Ive noticed i've got a mild case of heartburn especially at night and my heart seems to be beating to a different tune. Its been about 7 or 8 years since I ran a cycle but I don't remember this at all... Is this normal as body isn't used to it yet possibly? Suggestions....
