First delivery arrived on time and in safe styrofoam box to prevent melting. I tried regular dose size a year ago with strong stomach side effects and so far the microdose has not caused any side effects at all.

Lisa
I've been on a Glp1 for over 2 years and wanted to switch to a compound to decrease cost. I was able to show proof of my current Rx and stay on the same dose. Communication around the dose was a little tricky, so it took about 3 weeks..but it all worked out. Shipping was seemless and fast. I am so happy I have a solution for long term maintenance at a more affordable price.

PlexusDx is a genuine, reliable provider that truly cares about its clients. My experience could not have been better. Beyond their attention to detail and rapid customer service response, I was approved by a medical practitioner the same day, and my medication was overnighted the following morning. Having had negative experiences with other compounding pharmacy websites, I thoroughly researched PlexusDx before placing my order. I discovered a legitimate, stable company that is clearly committed to outperforming the competition through a genuine dedication to customer satisfaction. I highly recommend them.

David B.
Last year I went on a regimen of GLP-1, .25 for 4 weeks, .5 for 4 weeks, and 1 for four weeks. I lost 25 lbs. I gained it back, so this year I started again with Plexus. No weight loss at all, in fact I gained weight. The fact that one of the vials was 20 units short is kind of irrelevant. Every now and then I'd email them to tell them what was going on, response was someone would get back to me right away, that went back and forth for 3 weeks before a doctor responded and it really didn't clarify anything. So I'm out >$400 with nothing to show for it. I'd give a zero star if it was available. Now they want me to sign up for another 3 months. Yeah.

David, sorry to hear about your experience. We will reach out confirming a full refund. -Adam Valentine, COO
CRYSTAL M.
The entire process with this company was incredibly streamlined. After you answer the personal questionaire *honestly*- a doctor reviews it. For me this was all done within a couple hours. The medication was shipped within hours of me paying. Very fast. Flat fee, no hidden fees. I paid what they said i would pay, no monthly subscription. The communication with the doctor and the customer service have been great, no complaints at all. They communicated all instructions, and I can contact them anytime I need them. I'm super happy I decided to go with this company for my care!!

Crystal, thank you for sharing. Your review is an example of a full team effort. I will be sharing this on our Monday team meeting! - Adam Valentine, COO.
Lorie
Great experience, the response from the provider was fast, efficient and felt personal when there was some questions about my health history. I received a check-in after starting as well as some great recipe and meal plan ideas which was more than expected and appreciated. So far, the medication has been effective and little side effects.

Lorie, experiences like yours are always great to hear. The team puts a lot of work behind the scenes so our customers can just concentrate on their health. -Adam Valentine, COO
