Three years ago I started following Dr. Burke and lost 65 kg of weight, I came to live from Jordan to America and started getting Dr. Burke products, they are wonderful and useful and solved all my body problems, fatigue and lethargy.

Taking tbem as indicated, I dont feel jitters but also no burst. Is it working? 🤷♂️🤞 As with all these products, if you are not measuring your blood before & after over time, who knows if they are helping 😒🤷♂️🤞
