7 year user

for all the guys out there who aren't sure if this will work, don't feel good, have been ripped off or whatever - AlphaViril WORKS! I've been using it over 7 years. It's changed my life!!! That's all I have to say =)

don't take it every day

body-brain-energy is great, works better than other products I've tried. But don't take it every day. I noticed taking 1-2 days OFF each week makes it work better.

better blood to hands + feet

It's a bit embarrassing, but for the past few years, I typically have cold hands and feet. Even when it's warm outside. I don't like shaking hands because of it. But after 3 months of using BFO, they are much warmer. My hands look younger too.

my friends mom recommended it

there are so many products on the market, I wasn't sure what to do or which to take or who to trust. Luckily, my friend's mom told me about this product since she's been using it for a few years. It's been 2 months, 2 bottles, great results so far =)

glucometer readings

My fasting blood sugar in the mornings was averaging between 115-130. Not bad, not good. After 2 months of Blood Sugar Optimizer, it's averaging around 95-105. It's in a healthy range now. Its working. No change in diet. Will give another update in 2 months

using this for 10 years!!!

I've been using this for almost a decade now. My cholesterol and other levels are all in a healthy, good range. Sometimes a little higher and other times, perfection. Best part - no negatives, no drugs, I feel great, my doc is happy.

perfect combo

I eat about 3 hours before bed. An hour before sleeping, I take 2 pills of Deep Sleep Formula (sometimes 4). I take 2 pills of Stress & Cortisol Relief (also by Dr. Sam). I take 400 mg of magnesium. 1000 mg of Vit C. I sleep a solid 8-9 blissful hours every night!!!!

less shoulder pain

I take more than the recommended dose, I take 6 a day. My shoulder pain is at least 75% less. I'm not exagerating. It's been 2 full months of use. Maybe it'll continue getting better.

11 happier years

this is my 3rd review for Provanax. I've been using it for over 11 years. I'm happier, less anxious, worry less, more positive and just more confident. I have tried other products, cheaper ones - they all failed compared to this. Please NEVER STOP making Provanax, it's my "happy pills" =)

better vit D levels

Ever since I've been using perfect Vit DK by dr Sam, my vit d blood test levels have been higher. I'm using the same dose, but this brand seems more powerful or my body is absorbing it better I guess. Oh, my Vit K levels are in a healthy range now as well - double bonus! =)

saliva test shows it works

I took saliva cortisol/cortisol tests and to my surprised, taking Dr. Sam's Stress + Cortisol Relief herbal solutions actually improved my "negative" stress hormones. I was pleasantly happy and surprised at the same time that something actually works!!!
