Quick answer
Creatine monohydrate saturates muscle at about 0.3 g/kg per day for 5 to 7 days, then 0.03 g/kg per day maintains it. Skipping loading works too, just slower.
loading = 0.3 g/kg/day; maintenance = 0.03 g/kg/day

Frequently asked questions
Do I have to load?
No. Skipping the load reaches the same muscle saturation in three to four weeks with less bloating and stomach upset.
Is monohydrate better than other forms?
Yes for value and evidence. Monohydrate is the most studied form and the alternatives cost more without proven advantages.
What do I need to enter into the Creatine Dose Calculator?
Just 3 values: body weight, approach, tub size. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Creatine Dose Calculator work out the answer?
