  • Magic pill?!

    Overall Experience:

    I have been disabled since 1987 with mega injuries from head to toe; wheelchair stuck, cane, no nothing (malls, stores).

    Through the years I have literally purchased every joint/pain relief on the market but to no avail. I spent thousands and thousands of money looking for relief.

    I ordered the Instaflex 14-day trial. I saw a marked improvement in pain, flexibility, and overall mood.

    I ran out of IA two days ago and am really feeling the loss. Those old pains were on the way. I can feel pain creeping in!

    A life pain-free...never ever thought you would hear this from me.

    People claim the price is too high. you have a choice: purchasing meds that do not work ($35 to $69), or Instaflex Advanced ($35-$69). So aren’t you worth it? What is the price of pain?

    Bottom Line: Yes, I would recommend this to a friend


  • Instaflex is a scammer.

    Overall Experience:

    This Instaflex company is a scammer, don't order their drug. Immediately after you order it, they will be removing money from your bank account and mail you a drug you did not order. Secondly, their drug is not good nor working; when I took it I didn't see any improvement at all.

    Bottom Line: No, I would not recommend this to a friend


  • Rip off

    Overall Experience:

    This is the most dishonest company around. They talk about fake reviews, stop selling a fake product and misleading people. I paid $4.99 for the sample pack. Don't fall for the $29.95 deal, it's not a bottle, it's just another sample pack. But they call it a travel pack. Biggest rip off ever. Turning them into the Better Business Bureau.

    Bottom Line: No, I would not recommend this to a friend


  • Seems to be effective.

    Overall Experience:

    I've been taking Instaflex for about three months...I find it to have helped quite a bit. My knee is arthritic and probably has limited cartilage. I'm trying to hold off knee replacement as long as possible...I have better joint flexibility and less pain.

    Bottom Line: Yes, I would recommend this to a friend


  • Should have read reviews

    Overall Experience:

    While the first two days my knees improved quickly, I was not prepared for the cramping and diarrhea that began. Each day diarrhea became increasingly worse. Really disappointed because my shellfish allergy limits available product choices.

    Bottom Line: No, I would not recommend this to a friend


  • Really works

    Overall Experience:

    I usually go in for Cortizone Shots every three months. I’m on my third bottle this month and no shots. These pills work, the knee pain is 75% better and I’m happy for that. Just ordered 5 bottles!

    Bottom Line: Yes, I would recommend this to a friend


  • It works for me!

    Overall Experience:

    September 19, 2019 is my second week of taking Instaflex Advanced. A friend recommended this product as it helped her with arthritis pain. I have lived in 24/7 pain due to Osteoarthritis. I refuse to take prescription medication so I was willing to try anything. I felt better from day one. I have arthritis in my back, hips, pelvic bones and left knee. Walking was very difficult and painful. I took one capsule of Instaflex and 2 extra strength Tylenol in the morning and I was able to walk better with very little pain. I'm about 80% better! This product works for me and I'm very thankful to have found something natural to help me. I got the 14-day free trial to test the product. I'm now on monthly auto-refill. Thank you, Dr. Katz, for creating something that works great!

    Bottom Line: Yes, I would recommend this to a friend


  • Trial offer

    Overall Experience:

    I called about a refund because I had no idea by agreeing to their Terms about having a full bottle sent to me. So I called and I have been lied to with phone call (5 times) now. I called a few minutes ago and was given a different story about my refund. I have a dispute against it with my bank and they tried telling me in another lie my bank refused the refund.

    Seriously, how stupid just Instatflex think I am, being 63 I've been around the block a few times. I even went the distance to contact the BBB and the Consumer Rights Commission and Legal Aid. Being disabled, like I told them in the beginning, do they think they have the right to get me to jump through hoops for them? All this DRAMA because personally I think the product is a joke and their Customer Service is even worse acting towards customers who want a refund. All we hear are lies and more lies, it's just right and I have a strong feeling they will pay for it strongly.

    Bottom Line: No, I would not recommend this to a friend
