📝 How to Start Taking: Step by Step
For beginners, we recommend following this simple but effective plan to achieve the best results and avoid unnecessary side effects:
Week 1 — Start: Start with the lowest recommended dose (usually 50% of the standard). Monitor how you feel. Record your observations: energy level, sleep quality, digestion.
Weeks 2–3 — Gradual Increase: If you do not experience side effects, increase the dose to the full recommended amount. Continue monitoring how you feel.
Weeks 4–8 — Full Effect: The full effect of most supplements appears during this period. Evaluate the results objectively — did strength, endurance, well-being, and sleep quality improve?
After 8 Weeks — Evaluation: Decide whether to continue taking it. Some supplements require breaks (cycles), while others can be taken continuously. Consult a specialist.
💡 Document Your Progress! Record doses, dates, and subjective sensations. This will help objectively evaluate the supplement's effectiveness and make informed decisions about further use.
⚠️ Reminder: Supplements are supplements — not replacements. A balanced diet, sufficient sleep, and an appropriate training program are the foundation. Supplements only help achieve better results.
