I just had my second shot and nothing has changed on my body but I guess is too soon

Works but is expensive. Was hoping for faster weight loss and more energy overall. I also have some nagging queasiness but nothing unbearable. The increased cost each month is getting hard to afford which is the biggest concern. Works to curb appetite and food cravings, but that’s really the highlights.

I’ve been a good customer for a while, I placed a large order in less than eight hours later you put out a 20% promotion, you would not honor it , adjust the price or give me a future percent off the next order, you said there was absolutely nothing you could do.

I have only taken 2 injections, so really too early to give honest review.

I have been taking NAD regularly as instructed and have not noticed any results. I decided to do further research on VITAstir and dosing and found this (see below). Looks like they only dose at less than half the recommended amount. Otherwise ordering, shipping and delivery is pretty good but if the dose is too low there’s no benefit for the $$. I will reach out to customer service and update my review when I receive a response. “Evaluating 20,000 mcg (20 mg) Dosage Frequency: If you are considering 20,000 mcg (20 mg) three times a week, this totals 60 mg per week. Comparison: This amount is on the lower end compared to typical NAD+ injection dosages, which range from 50-200 mg per injection. Effectiveness: While some individuals may respond well to lower doses, many studies suggest that higher doses (around 500-1500 mg per week) may be more effective for significant benefits. Conclusion A dosage of 20 mg three times a week may be insufficient for optimal NAD+ levels, especially if you are targeting specific health improvements. It is advisable to consult with a healthcare professional to determine the best dosage tailored to your needs.”

The process of ordering is easy. Timely delivery of your order. Once the product was broken on delivery and it took more effort than necessary to get it replace. Take photos of your package. Coupon codes are a good way to re-order. Wish they offered loyalty discounts.
