21-Day Challenge FAQ
Can I do the challenge with just Formula 1?
You can, but adding PDM makes shakes much more filling. 95% of successful challengers use F1 + PDM together.
What if I miss a day?
Don't quit! Just continue the next day. Consistency matters more than perfection.
Can I have 1 shake instead of 2?
Yes – replace breakfast with shake, eat balanced lunch and dinner. Results may be slower but still effective.
Will I be hungry?
Not if you add PDM to shakes and drink enough water. If hungry, add more PDM or have protein bar snacks.
Can I exercise during the challenge?
Yes! Light to moderate exercise is encouraged. Add Rebuild post-workout if training hard.
What if I don't like Vanilla?
Try Chocolate or Café Latte instead.
Can I drink alcohol during the challenge?
Best to avoid for maximum results. If you do drink, limit to 1-2 drinks and choose lower-calorie options.
How much weight will I lose?
Results vary. Most people see changes in measurements, energy and how clothes fit. Focus on overall wellbeing, not just weight.
What happens after Day 21?
Continue if it's working! Upgrade to 780g Vanilla for better value.
Can I do the challenge multiple times?
Yes – or transition to ongoing daily use (1 shake per day long-term).
After the Challenge – What's Next?
Option 1: Continue Same Routine
✅ Keep doing 2 shakes + 1 meal daily
