Quick, simple, easy
I wanted to get a face cream. I was looking for this type of cream for a while and this website has the best price. I ordered and it was a very easy a quick process. I filled out the questionnaire, received a quick approval, paid for the product and received it within 2 days. Great service. Thank you
Great job. Quick response.
I noticed I put the wrong number in my address after I already sent everything. Thought for sure that was going to be a mess. Sent them a message and they fixed it before it shipped. They even let me know it was corrected so I wasn’t sitting there worrying about it.
No surprises at checkout
I liked that I didn’t have to hunt around for the real price. Everything was shown upfront and what I saw was what I paid.

B12 injectable FAQs
What happens after I start?
Answer a few quick health questions online. It takes about 2 minutes and it’s free. Then check out once: your card is only held, not charged. Verify your ID and answer a few last health questions, and a licensed provider reviews your request within 24 hours. If approved, you’re charged and your B12 ships. If nothing is approved, you cancel, or the hold expires, the hold is released, so there is nothing to refund. A prescription is not guaranteed.
What does the $65 cover?
$65 covers 10 mL of B12 (50 mg total), with syringes, needles, alcohol wipes and shipping included. There’s no visit fee. You’re only charged if a provider approves.
Is this a subscription?
No. It’s a one-time purchase. No membership, and nothing renews or refills on its own.
What if I’m not approved?
