I'd rather do Test only, and throw in a non-methyl PH. (If your newb and care).
Test should always be your base... (IMOSI) (old school opinion, just means I'm old).
I have to agree with this statement! I'm a college football player currently I'm 22 years old as well. Started when I was 20. My first cycle was just Test-Prop. I'm so happy i listened to the people who have experience. Start off right bro.
First cycle just run Test-E or Test-P for 10 weeks and call it good.
Now if you are stubborn and are set on Deca only be prepared for Deca D*ck.
Since your new, what are you going to PCT with and what AI are you going to have on hand? NEVER start a cycle without PCT and AI on hand!
You may think you have done alot of research but trust me there is alot more to it than you think!
Lastly, all these guys that have replied to your post are no rookies and know their stuff like no other! Dont be stubborn and listen to them bro! Gear isn't something to just "mess around with"
If you want you can PM with more specific questions!
