At your height I would get up to about 180-185 lbs before hitting the sauce for the first time. I did it that way and glad I did.
Drop the deca altogether, you need to evaluate how your body responds to running just one compound for the first time (the base hormone testosterone). Have an AI on hand but dont use it until you have to because, once again, you dont even know if you need it or not. Some guys need more AI than others. If you use the AI from the start you wont know if you even needed it in the first place. Always do cycles with as little different drugs thrown in as you can get away with.
Raise the test dose to 375/wk for 10 weeks, broken into two equal shots spread out in the week (like Sunday/Wednesday or something)
Cheers for the advice, will definitely go with the test only and 375 sounds good. I have always been quite light, difficulty putting weight on but loose it in no time, dads the same. I know i could grow more naturally, and im sure a good percentage of users could, but here we are. Most my mates just throw dbol down their throats before a workout, these guys only been training about a year.
