Wanted to share this story from a chat with a community member. She is 36 years old and has been struggling with Inflammation, edema (water), is the tension for the past six years. Tried a variety of functional protocols and made only small amounts of progress. After being on Reta around 2 mg/week for the past six months, she has lost 11 lbs., And is in the best shape of her life! I hadn't seen her for the entire six-month period, and it honestly took me a few minutes to recognize her, which is a testament to how transformative these molecules can be!

Part two of the GLP Metabolic Chemistry series is here. Episode one was a great discussion, and if you missed it, the replay's already posted here in the community. This time we're going deep on dosages and protocols: titration schedules for the various GLPs, how to adjust for patient response. We'll also open it up to the clinical questions we didn't get to last time, including combination strategies and how to handle patients who aren't responding as expected. We may even end with a vote on where we take the series next. I have a feeling GLPs are going to win that one :) https://zoom.us/webinar/register/WN_HCJStV-7Sj-9tgsKnxPtAA#/registration This will be Thursday, August 13th at 3 p.m. PST. Register and you'll get the recording either way. Looking forward to seeing you there!

Hi Awais, Thank you for sharing such great info. I am just ordering my first order of peptides. I’m trying to understand the math behind peptide reconstitution, not just one specific peptide. When reconstituting a lyophilized peptide with bacteriostatic water, how do you decide how much water to add? I understand that adding more water doesn’t change the amount of peptide—it just changes the concentration, so you’ll inject more or fewer units for the same mg dose. Is there a general formula or method you use to determine the reconstitution volume so the dosing is easy to measure? For example, if someone wanted a 0.5 mg dose from a 5 mg vial, how would they choose the amount of bacteriostatic water to add? Of course we can figure out the math, but is there an app or something that's just quick and easy. I’m trying to learn the calculations so I can apply them to different peptides. Thanks!

Let's get right into it: How much of the weight people are losing on GLPs is coming from muscle and not fat? Some of the research and clinical data is staggering. In the landmark trials: - Semaglutide (STEP-1): ~15% body-weight loss over 68 weeks, with roughly 40% of that loss coming from lean mass. - Tirzepatide (SURMOUNT-1): ~21% body-weight loss, with about 25% from lean mass — a more favorable ratio. Because tirzepatide drives larger total loss, the absolute pounds of muscle at risk can be similar or higher, and newer real-world (routine-care) data in 2026 actually found greater relative lean-mass loss on tirzepatide than semaglutide over 12 months. Translation: don't assume the "better" drug protects your muscle for you. Neither does. You do. On the positive though: in studies where people paired their GLP-1 with enough protein and resistance training, lean-mass loss dropped to nearly nothing, on the order of 1–2 lbs total.. Why it happens (the mechanism, briefly) GLP-1 medications are appetite silencers. They mimic your gut's own glucagon-like peptide-1, slow gastric emptying, and blunt ghrelin, the "I'm hungry" hormone. You simply eat less, often dramatically less. The 3-part muscle-preservation playbook: 1. Hit a real protein floor every single day. The evidence target for preserving lean mass during weight loss is at least ~1.6 g of protein per kg of body weight per day. On a GLP-1, where appetite is suppressed, the practical rule is simpler: never drop below ~100 g of protein a day, and aim higher. For most people that looks like 2 protein-anchored meals of ~40–50 g each, topped up with a whey or essential-amino-acid (EAA) shake. Protein is also the most satiating macro, so this is the easiest one to defend even on a tiny appetite. 2. Front-load leucine (whey + EAAs are your friends). It's not just total protein — it's getting enough leucine per meal to actually trigger muscle-protein synthesis. Whey protein and EAA supplements are the most reliable, muscle-preserving way to do this when whole-food appetite is low. One or two servings a day covers most people who are struggling to eat.

I recently had a client react to tesamorelin. They'd been on tesamorelin for a few weeks. Small dose, titrated up slowly, five days on and two off. Then one night the injection site got itchy and hard. Not the usual sting. It stayed raised and inflamed for a couple of days and they ended up taking a Benadryl. Here's what made it easy to pin down: that shot was the only thing they'd done that evening. Everything else in the stack had gone in that morning. The timing isolated it cleanly. Had they taken it all together, I'd have been guessing. So we stopped. That's the part I want to underline, because the instinct is to push through, or drop the dose and keep going. Once the immune system is on alert, giving it more of the same class right away just teaches it to reject the next one too. You have to let things quiet down first. Then the good news. Reacting to one GH analog doesn't mean you're done with the category. This client had done beautifully on Sermorelin. The clinical data isn't clear as to why some people are sensitive to a certain peptide and others aren't. But I feel that's the beauty of this evolving field, and I hope we are able to discover more about what causes some of these bio-individualities. I'm curious, has anyone from the community experienced this type of a sensitivity or reaction, or heard of something similar happening? Would love some thoughts
