AI for a 19 year old? and
Anabeta elite...? 2 natural hormonals for an under 21 would be against even my undefined code-of-conduct...so dose those as per the bottles already innate recommendations

.
As far as the
Pro Complex Gainer:
-Take 1 scoop and dump in the toilet
-Repeat until empty.
-Replace with a diet based on 1g of protein per lb of body weight , .5g of fat per lb of bw , and also carbs to fulfill the rest of the caloric allotment which will be in a surplus because you will dose ArA like such:
-1.5-2.5g pre workout (if
X-Factor then 6-10 caps)
-2g LCLT along with it
-6-8g of GMS , so around 3 scoops of
Glycergrow)
Staples:
-3g ~ of
Beta Alanine everyday (around 3.2 to 4.5g should suffice for the first 12 weeks, then you can dose it 4x a week since it saturated by then)
-3-5g of
Creatine Monohydrate or
Magnesium creatine chelate, you can decide to dose it every day or only 4x a week , no need for a loading phase.
Both of those above, take them post workout , creatine all at once ,
beta alanine in separate doses.
Fish oil around 3-5g of EPA/DHA. (3g is all you need iMO).
Dose them at least 4-6 hours away from the ArA dosage.
Anything else?
