GLP-1s are peptides. The P literally stands for peptide. Your body makes its own GLP-1 after every single meal, and it's gone within a couple of minutes by design. The drugs are that same signal, engineered so it never goes away, and that one difference explains both how well they work and almost everything women struggle with on them.

In this episode I break it all down. What a peptide actually is, how peptide drugs are built, and what your own GLP-1 does in your body. Then how to raise your own GLP-1 with protein, soluble fiber, healthy fats, fermented foods, meal order and how fast you eat, with real meal ideas (and why fasting doesn't raise it the way people think).

Then I go drug by drug: semaglutide (Ozempic, Wegovy, Rybelsus), tirzepatide (Mounjaro, Zepbound), retatrutide, the new oral GLP-1 pill, and generic semaglutide here in Canada. We talk half-life and steady state, what the labels actually say about dosing, what microdosing really means, what's different for women (bone, muscle, fertility and hair loss), and what happens when you come off.

I start with a personal story too: I sliced my finger open this week, and how my meditation practice let me regulate my nervous system in the ER.

The LongHer Life, formerly Biohacking with Brittany, is the podcast for women who want to live longer and better, from hormones and peptides to meditation and energy.

This episode is for education only and isn't medical advice.

This is my live masterclass, The Exhale, from September. A few hundred women showed up live, and it's one of my favourite classes I've ever taught, so I'm giving you the whole thing here.

We go deep on peptides, longevity and the nervous system, and why the mind and nervous system have to come first before the body work and the advanced tools. I share my own postpartum anxiety story, the pattern I keep seeing in women, and why we can't out-peptide a dysregulated nervous system. Then I break down how cortisol shuts down growth hormone peptides, undoes gut peptides like BPC-157 and KPV, overrides sleep peptides, and why GLP-1s without protein, strength training and nervous system work put your muscle and bones at risk.

A note before you press play: about 18 minutes in there's a 12 minute guided future self activation, eyes closed. If you're driving, please don't close your eyes. Just listen, and come back to it when you can sit or lie down.

It ends with a full live Q&A: Retatrutide and microdosing, protein hacks and powders, MOTS-c and SS-31, creatine, BPC-157 and TB-500 for inflammation, glutathione, fasting, Kisspeptin before IVF, and labs.

If you want to do this work with me, work with me one on one. My three month program is open, I also do one off consultations, and you can book a free 15 minute call.

Part one was how to look like yourself again. Part two was how to feel like yourself again. Part three is who you actually are, and it's the one that decides whether any of it sticks.

I open with something heavy from this week: I can't talk about peptides on Instagram anymore. I had to archive about 20 posts, my TikTok was deleted, and I've been blocked from DMs for three days. So I talk about building on borrowed land, and where I can still speak freely.

Then the three women I meet over and over. The one who knows exactly what to do and still hasn't started. The one who changes for a few weeks and then life creeps in. And the one who's waiting to feel ready. I go into why willpower runs out, why it's cyclical and tied to your hormones, and the five days I took completely off this month while my HRV sat in the 80s.

Then what actually builds it: deciding who she is out loud instead of setting a goal, one decision a day that she would make, changing the inputs instead of the intentions, and refusing to do it alone. Plus the question I asked a client this week that stopped her cold: what does it cost you to feel like this for another year?

This is for education, not medical advice. If you want to do this work with me, The Spark is open, and there are three spots left. One on one, 12 weeks, future self activations plus labs, nutrition, protocols and peptides.

Today is how to FEEL like yourself again, and better, because you can get the body and still not feel like you.

I start with the sentence I hear on every call: "I just don't feel like myself." Then the three ways it actually shows up. Feeling flat with no spark, even when life looks good on paper. Tired but wired, snapping over nothing, awake at 3 AM. And numb, living in your head, disconnected from your own body.

Then the solutions. Breath and long exhales, heart coherence at about six breaths a minute, and what your HRV and resting heart rate are really telling you. The labs I want you to look at, including a four point cortisol test and blood work through Function Health. And the deepest one, the future self activation I do every morning, plus the alignment questions that decide whether any of it sticks.

If you want to do this work with me, The Spark is open. One on one, three months, activations plus labs, nutrition, protocols and peptides. There are 8 spots and application calls are 15 minutes.

I TALK ABOUT:

00:00 Welcome back, and what part 2 is

01:44 What women mean by "I don't feel like myself"

03:08 The Exhale replay, and The Spark

05:00 Feeling flat, with no spark

07:36 What flat looks like on your labs

09:04 Tired but wired, and the snapping

10:05 The cortisol curve and the 3 AM wake up

14:37 Numb and out of your body

I don't want you chasing the woman you were two years ago or before kids. I want you stepping into the woman you're becoming. This is part one of a three part series on how to look like yourself again, and better.

We get honest about weight and body composition: why lighter doesn't always mean better, why so many women are trading fat for frailty, and why a GLP-1 plateau usually isn't a dose problem. Across published trials of semaglutide and tirzepatide, lean mass makes up 25 to 39% of the weight lost, and muscle is the tissue that keeps your metabolism going.

Then I give you my three practical fixes: eat enough protein (one gram per pound of ideal body weight, front loaded in the morning), lift heavy with progressive overload, and stop measuring the wrong thing. I share how I weigh myself around my cycle, why I recommend a DEXA scan once or twice a year, my weekly training split, and the formula I use with every client: regulate your nervous system, build the foundation, then add peptides.

If you want me to build this with you, The Spark, my 12 week one on one program, is open with only eight spots.

I TALK ABOUT:

• 05:53 A three part series, and where my peptide content lives now
• 07:40 Why "and better": the future you, not the old you
• 11:43 Lighter doesn't always mean better
• 16:28 Trading fat for frailty
• 17:45 The GLP-1 plateau and muscle loss
• 21:34 Eating healthy and still losing muscle
• 24:31 Fix 1: eat enough protein (plus weighing and DEXA scans)
• 34:53 Fix 2: lift heavy and progressive overload

Part two drops tomorrow: the thing underneath how you look.

The LongHer Life, formerly Biohacking with Brittany, is the podcast for women who want to live longer and better, from hormones and peptides to meditation and energy.

This episode is for education only and isn't medical advice.

Welcome to The LongHer Life, formerly Biohacking with Brittany. To kick off this new era, I'm not giving you a list of supplements. I'm giving you me. These are 10 things you probably don't know about me, and some of them I've never said on the mic before.

I share why I outgrew Biohacking with Brittany, and I read you the letter I wrote to my old self to close that chapter. Then we go deep: growing up in South Africa and moving to Canada at 7, my parents' divorce and caring for them as a teenager, growing up very Christian and where I stand with faith and spirituality now, my breech baby and traumatic birth, and the postpartum anxiety and intrusive thoughts I didn't recognize until I came out of them.

I also open up about the hardest season of my marriage, how I pick up on energy, the signs I keep getting that I'm going to have twins, why I thought I'd never work one on one again, and what it's like being a visionary who still has mom guilt.

If you want to work with me, The Spark, my new 12 week one on one program, is open now. Early bird pricing and the first edition founder's box end September 27.

I TALK ABOUT:

00:00 Welcome to The LongHer Life, and why I changed the name

08:00 The letter I wrote to my old self

11:00 I'm South African

14:20 My parents' divorce

There are two maps of the same body that almost never get laid on top of each other. One is over a thousand years old and runs up your midline naming energy centers. One is about a hundred years old and runs up the same midline naming glands. In this episode I put them on top of each other, and then I add the peptides.

I go center by center, all eight of them, and for each one I give you what the ancient text actually says, what the modern reading says, the gland that lives there, what shows up in women's health at that center, the peptides that run it with honest evidence strength, and then a practice: an affirmation, a meditation, a visualization, and three questions to sit with.

I promise you there is not another podcast episode on this. The idea came to me in a meditation.

If you want me to build this with you, my new one on one longevity program opens in September and the waitlist is live now. I am at capacity and my 1:1 consults are closed, so the waitlist is the only way in, and spots go first come first serve: https://biohackingbrittany.com/pages/waitlist

I also share what is changing behind the scenes: the September rebrand, the new program structure that my A4M peptide therapy certification confirmed for me, the planner, the deck I am designing, and the psychic reading that I am not ready to share yet.

WHAT I COVER

• Why my one on one consults are closed, and what is replacing them in September
• The peptide certification moment: you cannot out-peptide a dysregulated nervous system
• Two maps of the same body, 1577 and 1927, and why neither one wins
• The classical colors are not the rainbow, and what they actually are
• Root and the adrenals: the CRH to ACTH to cortisol cascade, HPA dysregulation, and Selank
• Sacral and the ovaries: kisspeptin as the master switch, PMOS, MOTS-c and mitochondrial density
• Why a 16th century text called a woman's body cyclical, and research did not include us until 1993
• What can sit in the second chakra for women, said as gently as I know how
• Solar plexus and the pancreas: the most peptide dense place in your body, and why you have to ask for fasting insulin
• Heart and the thymus: the organ that teaches your body the difference between you and not you, and why roughly 80 percent of autoimmunity is female
• Throat and the thyroid: Hashimoto's, the full panel to ask for, and postpartum thyroiditis
• Third eye and the pituitary: growth hormone secretagogues, and the KNDy neuron circuit behind hot flashes
• Crown and the pineal: melatonin is not a peptide, most people take far too much, and Epitalon
• The 8th chakra: the aura, the soul star, and why the women who burn out are the ones holding the most people

I TALK ABOUT:

00:00 - What is changing in September, and why my 1:1 consults are closed

08:27 - The planner, the deck, and what a psychic told me

12:23 - Peptides and chakras: two maps of the same body

27:24 - Sacral: the ovaries, kisspeptin, PMOS, and MOTS-c

37:40 - Solar plexus: the pancreas, insulin resistance, and fasting insulin

43:03 - Heart: the thymus, autoimmunity in women, and thymosin alpha 1

49:10 - Throat: the thyroid, Hashimoto's, and the full panel to ask for

54:57 - Third eye: the pituitary, growth hormone peptides, and hot flashes

1:00:57 - Crown: the pineal, melatonin truths, and Epitalon

1:05:45 - The 8th chakra: the aura, the soul star, and what you carry out of a room
