We’ve made another important improvement to the Guardian Labs website! Our Certificate of Analysis (COA) page now shows which batches are CURRENTLY SHIPPING, along with their respective lot numbers. That means researchers can now take the lot number from their product, find that exact batch on our website, and cross-reference it with its independent third-party testing results. Some compounds have multiple batches shipping simultaneously, and each has its own corresponding COA. We’re not the first company to offer this level of transparency, but I’m proud that Guardian Labs is now part of it. Trust is earned through transparency, not just words. Check out the updated COA page: https://guardianlabs.life/certificates-of-analysis/

Imagine sitting down to a meal and realizing you’re satisfied with less. Later, you walk past the pantry and don’t feel the usual pull to grab a snack. Food is still enjoyable—it’s just taking up less space in your thoughts. That’s the kind of effect researchers are interested in with tesofensine: a compound that acts on brain signaling involved in appetite, motivation, and reward. What Is Tesofensine? Tesofensine is a small-molecule compound that affects three chemical messengers in the brain: - Serotonin, which is involved in mood and satisfaction after eating. - Norepinephrine, which helps regulate alertness and energy. - Dopamine, which plays a role in motivation and reward. It was originally investigated for Alzheimer’s and Parkinson’s disease under the research name NS2330. During those studies, researchers noticed weight loss among some participants. That observation opened a new line of research: Could tesofensine’s effects on brain signaling be useful for weight management? READ MORE on our Tesofensine Protocols page in the Classroom

When your appetite is lower and the scale starts moving, it can feel like everything is falling into place. But I want you to remember: we’re not just focused on losing weight—we want to protect the muscle you’ve worked hard to build. Smaller meals can make it surprisingly easy to fall short on protein, especially when you’re not feeling very hungry. So instead of waiting for hunger to guide you, make a plan for it. Here’s your coach’s checklist: - Start with protein at each meal. Think eggs, Greek yogurt, cottage cheese, chicken, fish, lean meat, tofu, or a protein shake. - Track it for a few days. You might be getting plenty—or you might discover you need to add a little more. - Keep strength training. Protein gives your body the building blocks; lifting reminds your muscles they’re needed. - Pay attention to more than the scale. Notice your energy, strength, recovery, and how you feel during workouts. - Don’t forget the rest of your nutrition. Your body still needs enough food, fluids, and nutrients to support your daily life and training. A commonly suggested protein range during weight loss is 0.55–0.73 grams per pound of body weight per day, though your needs may be different depending on your training and health. A dietitian can help you find a target that fits you. The goal isn’t just to weigh less. It’s to feel strong, capable, and energized along the way. 💙

Has anyone had any issues with hair loss with KLOW? My wife has been taking it for about 9 weeks now and she noticed her hair was thinning. There’s some new growth but not a lot. Any advice or insight would be appreciated!
