Calculate your creatine dose: loading phase, maintenance dose by weight.

Creatine monohydrate – the most effective supplement for increasing strength and muscle mass.
Based on body weight, the calculator provides a guideline for the loading phase (a higher dose in the first days, divided throughout the day) or the maintenance dose. Both paths lead to the same goal — higher creatine stores in the muscles. The loading phase achieves this within a few days, the maintenance dose — within a few weeks, so the difference is only in time and how it feels, not in the final result.
The loading protocol on which this calculator is based is described in the scientific literature: in a study published in 1992, creatine supplementation increased phosphocreatine concentration in skeletal muscle — used 20 g of creatine per day for five days, divided into four 5 g portions (Harris et al., 1992; review: Webb, Dietary Supplements and Functional Foods, 2006, p. 167).
The maintenance dose is most often stated in the literature as 2–5 g per day — a higher dose is not more effective, because muscle creatine stores have a limit, and the excess is excreted through the kidneys. The calculator above selects the loading or maintenance dose based on your body mass.

Is loading necessary? No. The maintenance dose every day gives the same result, only more slowly; loading is chosen when you want a faster effect and tolerate higher doses.
Is the water retained by creatine fat? No — it is water in muscle tissue; weight may rise slightly, but this does not mean fat gain.
Do you need to take breaks? Many people use it continuously; if you want a break, the store level slowly falls and then returns again with regular use.
