| 🥤 Energy Drink (250 ml) | 80-150 mg | Convenient, quick | Sugar, artificial ingredients |
| 💊 Caffeine Tablets (1 tablet) | 100-200 mg | Precise dose, convenient | No additional benefits |

Keep a food diary for at least 2 weeks. What works for your body is individual. Review the results every month and adjust your strategy.
Better 80% optimal nutrition every day than 100% one week and 50% the next. Consistency is the key to long-term results.
What works for your training partner will not necessarily work for you. Genetics, microbiota, hormones — everything is individual.
Do not rely on the scale alone. Measure body circumferences, track strength indicators, and take progress photos every 4 weeks.
Q: Is this strategy suitable for beginners?
A: Yes! Start with the basic principles and gradually incorporate more advanced techniques. The most important thing is to start and be consistent.
Q: How quickly will I see results?
A: The first changes (energy level, well-being) — within 1–2 weeks. Body composition changes — within 4–8 weeks. Sports results — within 8–12 weeks.
Q: Do I need to take supplements for this to work?
A: No! Supplements are only a SUPPLEMENT to a balanced diet and proper training. First sort out your nutrition, sleep, and training — only then think about supplements.
Caffeine was on the WADA List of Prohibited Substances from 1984 to 2004. It is now monitored but not considered doping. However, too high doses can produce a positive test!
Caffeine levels in the blood peak after 30–60 min. The best time for sport is 45–60 min. before training. Drink coffee without sugar and cream!
Caffeine can increase fat oxidation! Together with L-carnitine, the effect is even stronger. An excellent choice before cardio.
Yes, but the body adapts. After 2–4 weeks of regular use, the effect decreases. It is recommended to take 1–2-week breaks every 4–6 weeks to restore sensitivity.
Tablets provide a more precise dose and a faster effect. Coffee contains additional antioxidants. For sport, tablets are more convenient (you do not need to drink liquid before training), but coffee tastes better. Choose what is more convenient for you!
There is evidence that moderate caffeine intake (up to 400 mg/d.) does not significantly dehydrate, especially if you are accustomed to it. However, additionally drink 200–300 ml of water with coffee.
Caffeine half-life — 5–6 hours. This means that after 6 hours, half of the caffeine is still in the body. Do not drink coffee for at least 8 hours before sleep; preferably — after 14:00.
