Retatrutide starting dose
I finally bit the bullet and ordered some Retatrutide, 10mg. Have been really curious to give it a try, but I am a real chicken when it comes to needles lol I wanted to ask if anyone has suggestions on the minimum weekly starting dose? I don't know if weight/height/age make any difference to a starting dose or it's more of figuring out what individual effective minimum is by trial and error. For reference I am 5ft 2, about 145lbs and 45yo. Pretty healthy according to the latest blood work. Would love to get about 10ish lbs off, happy to take my time doing it. I was thinking of starting at .25mg per week, but unsure if it's too little?

@Anthony Hicks, I shall keep you posted. I am not going to start it just yet, as I am traveling to Europe in about 4 weeks. Just making sure I have all my ducks in a row for when I am back and ready to go :)

@Anthony Hicks , maybe it's time to plan a vacation out that way? I used to live in the UK, so this is going back to London for the 1st time in 17 years since I moved to Canada. I can't wait. I want to cry every time I think about it lol After this trip I am going to need all the help to get back on track, as it will be filled with endless lunches, dinners and drinks while catching up with so many friends. Retatrutide is on standby haha
Fix the Grid, Not the Gauge: The Mitochondrial Root of Hot Flashes
Hot flashes can be seen not simply as a hormonal problem but as the visible sign of a deeper energy imbalance a flicker in the body’s power grid. Hormones aren’t useless they’re powerful messengers that often help restore balance when the system is struggling. But stopping at hormones is like patching a leak without checking the plumbing. We have to keep asking questions, digging deeper into why those hormones became imbalanced in the first place. Our goal isn’t to mask symptoms or apply temporary fixes; it’s to understand the root cause at the cellular and metabolic level so we can create true, lasting repair. The people who trust us with their health deserve that level of curiosity and commitment. We serve them best not by handing out patches, but by rebuilding the system underneath so it doesn’t keep breaking. At the foundation of that system is mitochondrial health. Mitochondria are the cell’s generators, producing energy in the form of ATP. When they falter, the hypothalamus the region that regulates temperature, sleep, and metabolism loses its steady rhythm. The result is the unpredictable heat surges we call hot flashes. The process unfolds in stages. In the earliest stage, subtle redox imbalances appear: the ratio of NAD⁺ to NADH drifts, and tiny sparks of superoxide begin to escape from the electron transport chain. You might imagine this as a dimming lightbulb the current still flows, but the wiring starts to hum. At this point, magnesium glycinate, niacinamide (vitamin B3), riboflavin (vitamin B2), and taurine help stabilize the system. Magnesium anchors ATP, keeping energy stored until it’s needed. Niacinamide and riboflavin recharge the batteries (NAD⁺ and FAD) that carry electrons through the mitochondrial turbines. Taurine acts as a shock absorber, buffering calcium shifts and protecting delicate membranes. Together they tighten the circuits so electrons can move smoothly again. Early signs that this is working are better sleep, fewer afternoon energy crashes, and steadier tolerance to stress or caffeine. On measurable levels, heart rate variability (HRV) improves, fasting glucose stabilizes, and body temperature becomes more consistent.

Hello everyone! I am Olesya, a personal trainer, a coach, a wife and a mom of two kiddos. My friend and I own a personal training studio in Maple Ridge, BC, Canada. I seriously don't have a single photo of the studio, so that is pending. You can check us out though on Facebook under Susafit. My friend started it and her name is Susa, hence the name. Now we just say that she is Susa and I am the Fit one haha A mitochondria penny finally dropped for me at the end of last year sometime. Majority of my clients naturally happen to be women in that transition to menopause phase. And I see fat loss resistance over and over again. And it just didn't make sense to me why everything that is supposed to work just doesn't or doesn't work as well. Fat loss shouldn't be that hard in principal, but doesn't seem to be the case in practice in that specific demographic. And I do think it is the healthy mitochondria piece that is the missing one. So I am here I hope to learn and basically figure out a way to solve the world menopause problem 😜 On a personal level, I am turning 45 next month and hopefully still a few years away from hitting that transition. But my own personal goal is to thrive through menopause and beyond of course. @Anthony Castore , I heard you touch in today's webinar on menopause and your theory, I think along the same lines. Always happy to exchange notes.
