You won't know what's best for you until you try! Like said before; some grow good on low doses whilst others need more to grow on.
My first cycle was very light - 400mg Primo/week. Results: 10-12 pounds of WATER and FAT because of all the food and NO strength gains!
Second cycle was 350mg Prop/week + 350mg Primo/week. Results: 10-12 pounds of WATER and FAT again and absolutely NO strength gains!
Needless to say, it was really pissing me off that I basically did'nt gain any musclemass on those two cycles - I grew WAY more mass from my first creatin cycle!
So, cycle three was a massive 1500mg/week cocktail of goodies and FINALLY I grew - muscle this time!
On my fourth cycle now and am keeping the dosages to 1gr/week wich feels good. No question that I need higher doses to gain on, but I wish I did'nt - it would have been a lot cheaper! :-(
