Is it possible to microdose? What is the cheapest online service?

Want to lose about 20 lbs. Can I get on a low dose and lose weight slowly with minimal side effects?

I'm not morbidly obese but I absolutely classify as overweight.

I've never been able to lose weight.

My potential is approach is:

1. Using a LOW dose and slowly titrating up

2. Adequate protein and iron

3. Pray 🙏 Jkkk

Anyone have been in this situation and had success? What provider should I use?

And what would be the cheapest?

Willow? Hers?

Thank you in advance !
