B12 cannot be made by the body and must come from food or supplementation.
The above testimonials are from real AgelessRx customers sourced from Trustpilot.com. Your individual results might differ from the above testimonials. Testimonials are not a guarantee of future results.
The most common side effect reported is irritation surrounding the area where the injection is applied.
If irritation does occur, consider changing the placement of the injection on the body (i.e. alternating arms each week) to minimize irritation. If irritation continues to occur, apply an over-the-counter itch cream, preferably one with hydrocortisone.

FAQs
Why should I choose an injection over an OTC supplement?
Injections have better bioavailability than oral supplements as they bypass the digestive system completely, providing a direct supply of B12 into the bloodstream to fuel your body. Oral supplements might work for some, however, as we age, our ability to break down oral supplements often decreases.
The solution you'll receive contains 1000mcg of B12 per ml/cc.
How much B12 will I receive in my order?
Start by injecting 1ml/cc 1-2 times per week. If desired, you can slowly increase up to 2ml/cc 1-2 times per week, or as prescribed. Should you ramp up to 2ml/cc, contact our team to adjust your ongoing Rx.
How often do I administer the injections?

B12 supplements pass through the gut with absorption as low as 1-2%.
As the body ages, absorption often declines, making oral forms even less effective.
Injections bypass the gut to help absorb B12 effectively, supporting faster relief from fatigue and brain fog.⁹
