hey i got one for you buddy..heres my advice ive been working out for 3 years almost and my recommend is this if you want strength gains you got to change some things...make sure your getting 1g of protein per pound of body weight..thats so freaking important..split your workout in this order...chest and tri's/biceps and abs/delts and quads/back and calfs....then rest for a day or 2 then repeat...no2 depends all up on you....for some people your body adapts to it...meaning you will come to a point where it wont work no more..thats how the human body is...so its always good to cycle...the label says you dont have to cycle but if you experience this you should..besides i think everyone should cycle on any supplement they take...my best bet is take creatine and protein as of right now since you just started up again...my recommends...is cell tech from muscletech and optimum 100% whey protein...i use them and they worked awesome...thats why i recommend them...later once you really get some good off of that and want to try something new use no2...i recommend gaspari superpump 250...it worked best for me even though ive used the original NO2 it didnt do much...and besides make sure you have a fast metabolism so you will digest the pills for its full effects...eat six small meals a day....2 hours in between every meal...here you go...heres a little intro...you got any more questions just pm me...**make sure you always get enough protein...1g per pound body weight...
