tren for a 1st cycle is a bad idea---bad bad bad. until you get used to the feeling of gear, the sides, what is normal and what is trouble, stay away from tren.
1st cycle should be just test imho--it the base of every future cycle so it is good to see how you react (eg/ gyno prone etc). if enth, just pin 250 every 4-5 days and you will get all swole in short order.
