this is you guys first course? i know for me and a few other people when we had our first course , we all had very high BP and some guys had irreg heart beat, but this is effect of your body freaking,testies start shutting down production for the first time,all these changes going on in ur body. and its not just from the gear but from the higher intensity of the training you will be doing, 2nd and 3rd and so on got much better for me and raised doses with no problems at all, all i had was raised liver functions after maybe 2 years cycling on and off. i had a good dotor who would blood test me evry 2 weeks , moitor my liver and organs and blood pressure.
