I am 19 yrs old. I am 6ft 165pds and play baseball for a junior college which does not test for steriods. I am considering taking them because i need to get alot stronger and gain only a little weight ( up to about 175-180pds). I have a very high metabolism and have a hard time gaining weight also. I am a fast runner and need to keep my speed,agility and flexability cause im a shortstop. So my question is: what type of steriod should i use if im looking to gain a little weight (mass), alot of strengnth and speed during my offseason(Nov-Jan)(2or3months). Thank You very much and i cant wait to hear back.
