You could offer some suggestions
I do somewhat agree. If you could specify what you specifically want most improvement on (endurance, strength, power, etc.) there are plenty of products that can be suggested to best help depending on goals. Gaining mass will be most dependent on caloric intake rather than any set supplement plan (although they can help).
On a side not if you want more program and nutrition advice I would suggest hitting up those specific parts of the forum for the best suggestions.
