Where the book points at something real
The Complete Guide to Peptides for Women has a section called "Hormonal Support and Menopause Balance". After Part 7, you might expect me to dismiss it. I will not, because buried in it are pointers to some genuinely important science, and to a conversation many women are not having with their doctors.
This final part is about sorting the promising from the premature, and turning it into questions you can actually use.
Why menopause hits skin, bone, mood and metabolism at once
The book makes a point that is correct and underappreciated: oestrogen regulates far more than reproduction. It is involved in collagen production, skin moisture, serotonin signalling, bone maintenance, fat distribution and insulin sensitivity.
So when oestrogen falls during the menopausal transition, changes can arrive on several fronts at once. The book lists them: drier and thinner skin, collagen loss (around 30% in the first five years, as Part 1 noted), mood shifts, more fat stored around the middle, changes in insulin sensitivity, and faster bone loss.
That list is accurate, and seeing it together helps. Many women experience these as unrelated problems and take them to different specialists. They often share a single root.
Kisspeptin: real science, early stage
The book's featured menopause peptide is kisspeptin, and this is one of its better sections scientifically.
Kisspeptin is a natural peptide that sits at the very top of the reproductive hormone chain. It acts on neurons in the hypothalamus that release GnRH, which tells the pituitary to release LH and FSH, which in turn control the ovaries.
The book cites a 2020 paper in the Journal of Clinical Investigation by Abbara and colleagues, and a 2019 review on kisspeptin and polycystic ovary syndrome. That research is real and serious. Kisspeptin has been studied in fertility treatment, including as a gentler trigger for egg maturation in IVF, and in hypothalamic amenorrhoea, where periods stop because the brain's signal to the ovaries has gone quiet. The book mentions this last use too.
What the research does not yet show is that kisspeptin injections relieve menopause symptoms. After menopause, the ovaries have largely run out of follicles. Stimulating the signal from the brain does not restart them. There is interesting research on kisspeptin's role in hot flushes (the neurons involved in hot flushes are closely related to kisspeptin neurons), and a newer class of approved non-hormonal drugs for hot flushes targets that same brain circuit through a different receptor. But kisspeptin itself is a research tool and a fertility treatment in trials, not a menopause therapy.
Tesamorelin: the approved one
The book also covers tesamorelin, and it gets the key fact right: tesamorelin is an approved medicine. It is a GHRH analogue approved to reduce excess abdominal (visceral) fat in people with HIV-associated lipodystrophy, at a daily dose of 2 mg, which matches what the book states.
The book notes it has become popular off-label among women dealing with stubborn belly fat after menopause. That is where caution comes in. The approval is for a specific condition in a specific population. Using it for menopausal weight change is off-label, and it raises IGF-1, which is something any clinician would weigh carefully against individual cancer risk.
Still, the underlying observation is sound. Visceral fat tends to increase after menopause, and visceral fat matters more for metabolic and heart health than fat elsewhere. That is worth tracking whatever you decide to do about it.
The treatment the book barely discusses
Here is the gap in this chapter. The book describes kisspeptin as a "natural alternative" for situations where hormone replacement "may not be suitable or desired". But it barely discusses hormone replacement therapy itself.
For many women, menopausal hormone therapy is the most effective treatment available for hot flushes, night sweats, and genitourinary symptoms, and it helps protect bone. Understanding of its risks and benefits has shifted considerably over the past two decades, and for many women starting it around the time of menopause, the balance is more favourable than was once thought. It is not right for everyone, and the decision is individual. But it deserves a proper conversation before anyone turns to experimental peptides.
Your questions, ready to take in
After eight parts, here is how I would turn this book into leverage in a real appointment.
On symptoms: "I'm having [skin changes, mood shifts, sleep problems, weight around the middle]. Could these be connected to perimenopause, and should we look at them together?"
On hormone therapy: "Given my personal and family history, what are the actual risks and benefits of menopausal hormone therapy for me? Am I a candidate?"
On non-hormonal options: "If hormone therapy isn't right for me, what approved non-hormonal treatments exist for hot flushes?"
On bone: "Should I have a bone density scan? What's my fracture risk?"
On metabolism: "Can we check my blood sugar, lipids and waist measurement, and track visceral fat risk?"
On skin: "Is there anything prescription-strength, like a topical retinoid, that makes sense for me? And which over-the-counter peptides are worth trying alongside it?"
On anything experimental: "I've read about [kisspeptin, MOTS-c, others]. Is there any clinical trial I could join, or is there evidence I'm missing?"
That last question is the right way to approach the injectable side of this book. If there is genuine promise, there may be a trial. A trial gives you monitoring, a real product, and a contribution to knowing whether it works.
Where the series lands
This book combines a reasonable guide to cosmetic peptides with an unreliable guide to injectables. Read closely, it still teaches a lot: how skin peptides work, why label percentages mislead, what oral collagen does, where hair research is heading, and how many menopausal changes share one cause.
The women who get the most from all this will not be the ones who follow its stacks. They will be the ones who use it to ask sharper questions, of their doctor, of every product label, and of any book that promises timeless beauty in 30 days. After eight parts, you are equipped to be one of them.
This series reviews a consumer book, not a clinical guideline. Many injectable compounds it discusses are not approved for human use in most countries. Nothing here is medical advice. If you are pregnant, breastfeeding or have a medical condition, speak to your doctor before using any product.
