    Dr. Mayeda is the most thorough with his Medical appointments and by far the most knowledgeable MD.

    Extremely disappointed in this medical office. After being a patient for years of Kirsten…read moreMontgomery, they sent me to debt collections for what I feel is an illegitimate charge. I have NEVER been charged separately for an office visit and a CGM download in my entire 20 years of being a diabetic. I have had many endocrinologists over the years and have never had an additional charge for the doctor to review my CGM numbers with me?? Is that not included in the office visit charge? I had to contact my insurance company, their billing office, and finally office manager and they offered no resolution. I have no choice but to pay collections but I would NEVER return to this office because I genuinely feel scammed and taken advantage of as a patient. I will attach pictures, one charge billing code is for the office visit, the other is literally to download and review CGM number. Ridiculous, immoral, and UNETHICAL medical practices. Shame on you.

I know getting an appt takes a while but my understanding is that there is a shortage of endocrinologists so I'm happy to have found this practice.

    Endocrinology Medical Group of Orange County - Waiting room... It is actually much larger with several more chairs but I didn't want to take photos of patients as they were waiting.

In short: this program did not work for me, despite a full year of commitment and trust in the process. I'm a very active man in my 30s, and I was looking for a safe and effective boost--something in the realm of TRT-like results without going the traditional route. Unfortunately, Vitality RX did not deliver. 1. Misleading Progress & Poor Communication After six months, I was told my testosterone levels had improved based on their internal testing. However, I felt no noticeable difference--no changes in energy, recovery, strength, or mood. When I voiced my concerns, I was met with generic reassurances to "stay the course." The follow-up calls were short, rushed, and didn't leave any room for meaningful discussion. After a year, I saw an independent physician and discovered that my actual hormone levels didn't reflect the improvements I had been told about. 2. Repeated Errors & Lack of Accountability Throughout the year, I dealt with multiple shipping and prescription errors. For the price I was paying, I expected professionalism and consistency. Instead, I often received the wrong items, and the company would simply blame the pharmacy. That's unacceptable--Vitality RX is who I was paying, and I expected them to take responsibility. 3. Lack of Real-World Results Before signing up, I noticed something odd: there were no authentic user reviews or transformation videos on YouTube, TikTok, or anywhere else. That should have been a red flag. Now I understand why. In my opinion, this program is marketed as a convenient alternative to TRT, but based on my experience, it simply does not deliver results. If I could go back, I wouldn't have signed up. I hope this helps someone else make a more informed choice.

Reviews are one thing, but cold hard data doesn't lie. My 2-month follow up bloodwork showed my Total T level increased from 358 to 966 (+270%) and my Free T level increased from 8.0 to 22.1 (+276%) What's even more amazing is that, if you're in the LA area, they actually dispatch a nurse to you to draw your blood. I live in SF, but I was able to have my blood drawn at a hotel and at my friend's house. Talk about convenient!
