Excellent service, prompt delivery, and the product was as shown & of a high quality.
So far so good! Good ingredients.
I have been using Reta for 12 weeks and have lost 23 lbs and a total of 27.25 inches. I feel good and there have been minimal side effects as I started dosage low and moved up slowly to keep the weight loss steady but not enough to feel sick. Very happy with the products, service and results!!
Sterile and clean!
So far so good! This is a trust worthy source I’ve sent all my friends to.
