Like everyone else has stated you are a little young.But if I can at least give you an educational and responsible answer other then don't use gear yet,I wouldn't frontload your first time out.Your first cycle of gear is going to produce incredible gains,so your gonna want to use the least amount of gear possible your first couple of cycles.Reason:The more gear you use it will down regulate the receptor cites making it harder to see results with the same amounts of gear that you previously used ,so start small for as long as possible.I wouldn't go more then 500mg of Test E split into 2 doses for more then 10 weeks your first time out,and even know it's a long ester that will take a while to kick in like the 4-5 week you will still see a lot of gains.Don't use the armidex on cycle it will hinder the potential of the cycle cause your body needs estrogen to put on size so keep it on hand incase of gyno signs.When your cycle is over and no gyno concerns then use it for PCT with clomid.Look in the PCT stickys at the top of the PCT forum.And in my opinion Nolva has no place in PCT for a male bb,female yes male no.People use it yes but it has the potential to shut down you IGF-1 AND ONLY BLOCKS THE RECEPTOR SITE OF ESTROGEN IT DOES NOT ELIMINATE IT.
Now like I said I don't think your ready I don't care how long you've been training your 21 yo and looking to be a competitive bb then maximize your naturel potential with training,diet and dedication.There's so much info here on how to maximize gains without the use of gear so be patient.
