In the first 7 days of creatine loading you can expect a 1 to 3 kg increase on the scale mainly from water retention and glycogen storage, along with enhanced muscle fullness and short-burst performance. Mild bloating or cramps may occur but are usually easy to manage with proper hydration and spreading doses throughout the day.
There are several factors to consider, including hydration strategy, dosing timing, and when to switch to a lower maintenance dose, so see below for a complete day-by-day breakdown, side-effect management tips, and guidance on when to seek professional advice.
Starting a creatine "loading phase" can be an exciting step toward better strength, power, and muscle gains. Many people wonder about creatine and weight gain in first week, how much they'll notice it on the scale, and what other effects might pop up. This guide walks you through a realistic, no-nonsense look at days 1–7 of loading.
Creatine loading involves taking a higher daily dose of creatine monohydrate (usually 20 g) split into 4 servings of 5 g each, for 5–7 days. The goal is to saturate your muscle creatine stores quickly, which may:
After loading, you switch to a maintenance dose (3–5 g/day) to keep stores topped up.
One of the most noticeable changes is a bump on the scale. Here's why:
Most users see a 1–3 kg (2–6 lb) increase in the first week. Remember, not all of that is fat—it's mostly water and a pinch of glycogen.

Summary
In the first 7 days of creatine loading, expect a 1–3 kg increase in body weight—primarily water in your muscles. Mild bloating or cramps can occur but are usually easy to manage with proper dosing and hydration. By day 7, your muscles are primed for better performance and quicker recovery. After loading, switch to a 3–5 g daily maintenance dose to keep reaping the benefits.
