TL;DR

The four things you'd lose by not watching

4 items
1

Women's hormonal cycles make them more susceptible to metabolic inflexibility; Dr. Grill Peterson recommends circadian eating (three meals during daylight, protein-first, complex carbs) and avoiding >12‑hour fasts for premenopausal women to stabilize blood sugar and cortisol.

2

Female‑specific supplement stack: creatine 5‑10g daily, a comprehensive multi (B’s, magnesium, zinc, CoQ10), fish oil, and possibly DHEA/pregnenolone after labs in mid‑30s+ with high stress.

3

Peptides: Tessamorelin (FDA‑approved GH secretagogue) cycled 12 weeks on/5 days on‑2 days off twice yearly, half of women prefer it at night for sleep. Kisspeptin resets hormonal signaling. Retatrutide microdosing (12.5mcg 3x/week) is used preventively for longevity, not just weight loss.

4

For safe, clean peptides, use Peple (Vcelius) with mandatory doctor consult; avoid black‑market research‑only sites. Education available at Peptide University.

Circadian Eating Window for Women

WhatEat three nutrient‑dense meals during daylight hours (≈8am, 1pm, 6pm) with heavy protein, healthy fats, and complex carbs at breakfast; delay caffeine until after breakfast; avoid late, heavy meals and alcohol close to bed.
WhenDaily, especially during premenopausal years; adapt to individual ghrelin rhythms.
DoseNo strict fasting window; eat when light, stop eating as it gets dark. If fasting, limit to ≤12 hours for premenopausal women.
For whomWomen of all ages, particularly those with metabolic inflexibility, PCOS, hormonal imbalance, or high stress; post‑menopausal women may tolerate longer fasts like men.
WhyAligns eating with natural ghrelin surges and circadian rhythms, stabilizes blood sugar, reduces cortisol, improves metabolic flexibility, and prevents the ‘flip‑flopping’ of late‑day calorie load that disrupts sleep and recovery.
CaveatsHighly optimized women may already have flexibility and can experiment; if current approach works, continue, but if imbalances exist, try this gentler method first.

The expert frames this as an antidote to the standard ‘skip breakfast, drink coffee, train fasted’ advice that works for men but often backfires for women. She explains that women’s hormones are more sensitive to stress; skipping breakfast and piling calories late in the day when insulin naturally rises pushes the body into fat storage mode and disrupts sleep repair. By starting the day with a protein‑rich breakfast and ending food intake with daylight, women can restore a natural catabolic/anabolic rhythm. She also notes that during the menstrual cycle, women may need slightly more nutrient density in some phases, but the core structure remains the same. This protocol is positioned as a ‘step‑one’ before adding supplements or peptides.

Mechanism

Ghrelin, the hunger hormone, peaks in the morning, midday, and early evening. Eating in sync with these peaks improves glucose disposal, reduces evening insulin spikes, and supports the natural cortisol awakening response (high in morning, low at night). Delaying caffeine prevents early cortisol aggravation and allows a genuine appetite for a nutrient‑dense breakfast, which provides steady amino acids and fats for hormone production.

Personal experience

Melissa: 'I get up and I delay my coffee and I get a nutrientdense breakfast… I'm already in a more metabolically active state. I'm better able to utilize what I'm taking in.'

If I get up and I delay my coffee and I get a nutrientdense breakfast, I really get heavy protein. I get some really good healthy fats and I give myself some complex carbs. I don't try to keep it all away. I nourish my body and I do it in time with when those hormones want to naturally cycle.

Also said
“Most women are skipping breakfast, right? They're doing a lot of caffeine. Maybe they're eating a little bit of lunch, a larger dinner, and too much wine. And so, we're kind of inversing the way the body wants to naturally use the nutrient.”— Highlights the common pattern this protocol is designed to correct.

Creatine for Women (5‑10g daily)

WhatSupplement with creatine monohydrate, 5‑10 grams per day.
WhenDaily, any time; can be taken with meals.
Dose5‑10 g/day; no need to cycle.
For whomAll women, particularly active and aging women.
WhySupports muscle strength, cognitive function, bone health, and cellular energy (ATP); especially important for women who historically avoided it as a ‘male supplement.’
CaveatsStay hydrated; some may experience mild bloating initially. Creatine is well‑tolerated.

Ben emphasizes that creatine has been wrongly pigeonholed as a male bodybuilding aid, but research and anecdotal feedback show women respond excellently to 5‑10g daily. JJ Virgin is credited with popularizing it. The conversation frames creatine as a non‑negotiable foundational supplement, alongside a good multi and omega‑3s. No negative hormonal effects for women were noted; instead, it supports muscle preservation and brain health as they age.

Mechanism

Creatine increases phosphocreatine stores, enhancing ATP regeneration during high‑intensity efforts and supporting mitochondrial function. It also acts as a buffer against oxidative stress and may influence methylation.

A lot of women now are feeling really good on 5 to 10 grams plus of creatine.

Also said
“It it is an essential. It's in the toolbox. Um we we cannot underscore the importance still for women.”— Stresses that creatine is not optional but a core supplement.

Tessamorelin Growth Hormone Optimization

WhatCycled protocol of Tessamorelin (a growth hormone‑releasing hormone analog) morning or night, optionally paired with Sermorelin at night for a dual GH secretagogue approach.
WhenTwice‑yearly cycles, each 12 weeks long, 5 days on / 2 days off. Take in the morning for daytime benefits (lean muscle, fat loss) or at night if it improves sleep without disruption.
Dose12‑week cycles, 5 days on / 2 days off, twice a year. Exact dose not specified; typical is 1‑2 mg subQ daily. Ben adds Sermorelin at night for a complementary GH pulse.
For whomWomen seeking body composition changes, metabolic improvement, and deep sleep support, especially perimenopausal and post‑menopausal. Not for pregnant or breastfeeding women.
WhyIncreases lean muscle mass, reduces visceral belly fat, improves glucose utilization, and supports sleep architecture. As a secretagogue, it stimulates the pituitary to release the body’s own growth hormone rather than replacing it exogenously.
Caveats~50% of women find Tessamorelin improves sleep, ~50% find it disrupts sleep—test individually. If it causes sleep issues, move to morning or switch to a different GH peptide. Do not use continuously; cycle to avoid receptor desensitization. Only from a reputable source with medical oversight.

Melissa explains that Tessamorelin is FDA‑approved for HIV‑related lipodystrophy but is used off‑label for its GH‑releasing properties. Unlike synthetic GH, it preserves natural pulsatile release. She often starts women at night to leverage the natural GH surge during deep sleep, but she switches to morning if it disturbs sleep. Ben adds that he likes to combine morning Tessamorelin with night Sermorelin to cover both daytime and nocturnal GH pulses, reporting that this stacking has worked well personally. Both emphasize cycling—not staying on year‑round—to maintain receptor sensitivity and avoid cortisol/IGF‑1 interference.

Mechanism

Tessamorelin is a GHRH analog that binds to pituitary receptors, stimulating production and release of endogenous growth hormone. Increased GH enhances lipolysis, amino acid uptake, and hepatic IGF‑1 production, leading to improved body composition, glucose metabolism, and recovery.

Personal experience

Ben: 'I do 12 weeks, 5 days on, two days off. Uh test melanin in the morning, some or a Merlin at night. I do that twice a year. And you know that's going to vary from person to person. That's what works for me.'

Tessamorellin… it's going to help with not only with signaling, it's a growth hormone releasing uh you know stimulus. So, it's an analog that's going to go ahead and tell the brain, tell that pituitary, let's release some growth hormone.

Also said
“50% of my women love it for sleep. they get amazing sleep and they're like, I'm taking it at night and this is my jam. And others, they're like, it disrupts my sleep. I'm very sensitive to it.”— Highlights the split response and need for personalization.
“I'm going to start women more at night if we're wanting the really to go ahead and get deep sleep. For a lot of women, we need that.”— Melissa’s default strategy for women, then adjust based on tolerance.

Retatrutide Microdosing for Longevity

WhatInject a very low dose of Retatrutide (triple GLP‑1/GIP/glucagon agonist) 2‑3 times per week to smooth glucose metabolism and reduce stress‑induced gluconeogenesis without appetite suppression.
WhenMonday, Wednesday, Friday (Ben’s schedule) or twice a week (Melissa). Taken indefinitely as a preventive.
DoseBen uses 12.5 mcg (0.0125 mg) per injection. Dosing should be determined with a physician; start low and titrate to the lowest effective dose.
For whomIndividuals (especially women under high stress) seeking long‑term metabolic resilience and longevity, not rapid weight loss. Must be done under medical supervision.
WhyOffers pleiotropic benefits—cardiovascular protection, cognitive enhancement, blood sugar stabilization, improved lipid profile—while ‘stealing fire’ from cortisol’s glucose‑dumping effect and creating a smooth metabolic burn.
CaveatsCan cause nausea, fatigue, and low energy at standard doses—microdosing minimizes these. Only use prescription‑grade or high‑purity US/Germany‑made peptides from a source with doctor oversight. Not for those with pancreatitis or medullary thyroid cancer history. Monitor labs and symptoms.

Melissa and Ben frame microdosing Retatrutide as an innovative use of a powerful molecule beyond the weight‑loss narrative. Because women often experience constant cortisol spikes that dump the equivalent of a candy bar’s worth of glucose into the blood multiple times a day, the glucagon component of Retatrutide helps slow that release and shift the body into lipolysis. This creates a ‘smooth burn rate’ that reduces metabolic stress. Ben contrasts the engineered half‑life of pharmaceutical pens (weeks) with the short half‑life of pure peptide; microdosing avoids receptor overload and mimics natural GLP‑1 pulses. Both use it themselves and emphasize that the goal is optimization, not just weight loss.

Mechanism

Retatrutide agonizes GLP‑1, GIP, and glucagon receptors. Glucagon agonism increases hepatic glucose output in a controlled manner, promotes fatty acid oxidation, and reduces triglyceride synthesis. Combined with GLP‑1/GIP actions, it improves insulin sensitivity, slows gastric emptying (minimally at microdoses), and exerts neuroprotective and anti‑inflammatory effects.

Personal experience

Ben: 'I micro dose 12 and a half migs of reatride Monday, Wednesday, Friday. Now it's a baby dose that doesn't give me nausea. I still eat like a horse frankly. So for me the appetite suppression doesn't kick in so well just cuz I eat a lot of food.' Melissa: 'I also take a low dose. I take it twice a week. Um just again really more for the longevity effects.'

What I love about Red True Tide is that so if we think about this, every time there is a stress event… It's similar equivalent to about 24 gram like a candy bars worth of glucose being dumped into the bloodstream… What's so phenomenal about reatrite is really the effects of having that triple agonist that glucagon that is going to help to really slow down the amount… We become so much more efficient.

Also said
“I'm a huge fan of the micro doing strategy… I've settled into a triple GLP or a triple agonist um reatride. I micro dose 12 and a half migs Monday, Wednesday, Friday.”— Ben’s specific endorsement and personal dosing schedule.
“If we're taking Ozempic or Wegovy… that's been engineered differently than if we are getting a raw sourced research use molecule… So it makes sense that if we are dosing it a smaller dose more consistently, we are not going to oversaturate the receptor sites.”— Pharmacokinetic justification for microdosing versus standard prescribing.

Peple (Vcelius) Clean Peptide Source

Product Sponsored · disclosed

Peple (via Viselius) is a US‑ and Germany‑based peptide provider that manufactures in FDA‑registered, GMP‑compliant labs, with third‑party testing and high certificates of analysis. It requires a complimentary teleconsult with a doctor before dispensing, ensuring appropriate use.

DisclosureBoth Ben Greenfield and Dr. Melissa Grill Peterson are on the board of Viselius (parent company of Peple).

In response to the 2023 FDA recategorization that removed many peptides from compounding pharmacies, the market flooded with risky research‑use‑only products from Asia. Peple aims to disrupt this by offering physician‑grade peptides that meet the same quality standards as compounding pharmacies and pharmaceutical companies. Products are either injectable or in novel delivery forms, and the initial consult is free, valid for 12 months, so patients can reorder without revisiting the doctor for every change. This positions Peple as a trustworthy alternative to the ‘wild west’ of black‑market peptides.

vs alternatives

Contrasts with research‑only websites: no quality oversight, unknown fillers, and reports of LPS contamination causing histaminic reactions. Peple follows FDA guidelines akin to a compounding pharmacy, offering reassurance of purity and potency.

Personal experience

Ben: 'That's where I'm getting my peptides.' Melissa sits on the board and answers questions at conferences for the company.

They are coming out with total transparency. They do every most of their product is here in the US andor in Germany. They are FDA registered… manufacturing labs, clean, pure, third‑party tested, high certificates of analysis.
