I've been a patient at Lean Lab for the past 8 months, and I can honestly say I'm feeling the best I've ever felt. I receive a few different services, and the level of care has been amazing every step of the way. Provider Bianca is incredibly thorough, knowledgeable, and truly takes the time to make sure your treatment plan is personalized to your needs. The staff is always so attentive, welcoming, and genuinely caring, they make every visit a great experience. The office is very nice and one thing I really love is that their 6-month package includes a Myers' Cocktail IV, which is such a great added value and something I haven't seen offered anywhere else. I highly recommend Lean Lab to anyone looking to invest in their health. read more

Let me start this off by saying THANK YOU LEAN LAB!!! This place is amazing with a great staff like no other. Bianca and her staff are second to none when it comes to health and weight loss. They are all genuinely kind, patient and knowledgeable on the stuff they offer. My weight loss has been finally recognized by my friends and family and I give all the credit to this place. I came here for the weight loss as my doctor told me I have to lose weight so i can possibly get off the high cholesterol meds. I started this program about 4-5 months ago at about 188 pounds and today I weighed in at 158 pounds. I been trying to control my intake of food and also exercise throughout this journey. I also get B12/Glutathione for energy, better skin and immunity. Best provider I ever experienced in my 45 years!! More updates to come so stay tuned! This place is rocking the Pasadena area. I just wish they had a location closer to me in Rancho Cucamonga. read more

She took the time to review all of my bloodwork and even ordered additional labs in addition to my routine blood work just to cover all basis. The office is very nice and conveniently located.

I've been going to Lean Lab for three weeks and I'm already so glad I found them. I was looking for a local place that provided GLP-1 options at a reasonable price. It all started with a thorough consultation where they really took the time to listen. I was given a recommendation for where to get my labs done, and once those were complete, I went back within the week to get my first shot. Just one week later, I saw a 4.8 lb difference. Even more incredible is how much better I feel. My foot and back pain were almost immediately minimized, and that alone has made a huge difference in my day-to-day life. The service is kind, intentional, and knowledgeable. The whole team makes you feel cared for and confident in the process. The space is absolutely beautiful. It feels like a high-end spa, and the scent when you walk in is divine. They also work with your schedule, which makes staying on track simple and stress-free. I'm excited for the journey ahead and highly recommend Lean Lab if you're considering GLP-1 support in a welcoming and professional setting. read more

Lean Lab has been a game changer for me. I started on peptides and GLP-1 therapy, and within weeks I noticed real changes, not just in weight, but in how I feel overall. The GLP-1 helped curb my appetite and stabilize my energy throughout the day, while the peptides have supported my metabolism and recovery. Everything is adjusted to fit what MY body needs, and the team really monitors your progress closely. Also, shout out to Bianca, she is absolutely amazing, so extremely knowledgeable, kind, patient, and genuinely listens. She explained everything clearly and made sure the plan felt right for me. I've felt supported every step of the way. If you're looking for a personalized, medically backed approach to weight loss, I highly recommend Lean Lab read more

Lean Lab has been a game-changer for me. I started going for weight loss support and have lost 40 pounds with Trizepitide, and I honestly feel better than I have in years. From the very first appointment, the staff made me feel seen, supported, and completely at ease. They started with a 3D body scan, which gave me a detailed picture of where I was starting from and helped tailor a plan specifically for me. They've also added peptides into my routine to help with energy, recovery, and anti-aging, and I can see and feel the difference. The staff is kind, knowledgeable, and truly encouraging every step of the way. I actually look forward to going every week, it's become a highlight of my routine. read more

Finally local IVs! My husband and I travel a ton for work and boosting immunity/vitamins has really helped us stay on track with the back and forth, unfortunately finding a place that offers IVs has been a struggle, when I heard about lean lab we were super excited to try it out and it has been so easy/convenient and exceeded expectations. The office is very inviting and the staff were super friendly and knowledgeable. I love how easy it is to book online and review different options with the PA Bianca, who is able to really hone in on what you need. The process is quick and easy, not crowded and offers a nice change of pace. This will definitely be our new spot to recoup when needed, the location is also a plus! read more
