Best Peptides for Menopause

Peptides are gaining attention among researchers and clinicians for their potential role in a wide range of physiological processes, from tissue repair to hormone regulation. Many women going through perimenopause and menopause, as well as those managing PCOS, are asking whether peptides could help with symptoms like disrupted sleep, changes in body composition, low mood, reduced libido, and low energy. This guide covers the main peptides currently being researched or prescribed for symptoms related to menopause, perimenopause and PCOS, what the evidence actually shows, and where the science is still developing.

What are peptides for menopause?

Peptides for menopause work differently to hormone replacement therapy. Rather than replacing oestrogen or progesterone directly, most work through amino-acid signalling, prompting the body’s own systems, such as the pituitary gland or specific receptor pathways, to respond in ways that may ease symptoms linked to declining hormone levels. Research in this area is still developing, and evidence quality varies considerably between compounds.

Compounds studied specifically for their action on the hypothalamic-pituitary-gonadal axis, the hormonal pathway most directly involved in the menopause transition, are covered in our Hormonal Axis Peptides range. Related hormonal signalling changes are also studied in perimenopause and in PCOS, though the underlying hormone profile in PCOS, typically raised androgens and insulin resistance, differs from the oestrogen and progesterone decline seen in menopause itself. 

Common menopause peptides

Menopause involves a wide range of symptoms, from hormonal shifts to changes in energy, cognition, sleep, skin and sexual health, and researchers are exploring various peptides for their potential to support women through this transition. Evidence and regulatory status vary considerably across these compounds, ranging from preliminary preclinical findings to one FDA-approved treatment. Early research shows promise in several areas, but further human clinical trials are needed to confirm efficacy and safety before firmer conclusions can be drawn.

Ipamorelin

As a synthetic peptide, Ipamorelin stimulates the body to naturally produce its own growth hormone. Researchers are studying it for its potential to support fat loss, improve sleep quality, and encourage anti-ageing benefits such as better skin elasticity and hair health. Unlike other growth hormone-releasing peptides, Ipamorelin targets growth hormone (GH) release without heavily spiking cortisol or prolactin, which may reduce the likelihood of unwanted side effects.

Ipamorelin is not FDA-approved, however, and more conclusive clinical research is needed on its impact and safety in humans before it could be considered for use in a menopause context.

Semax

Semax has shown potential for improved cognition, with early research pointing to enhanced focus, boosted motivation, heightened concentration, and reduced brain fog, all common symptoms of menopause.

No rigorous clinical trials have specifically evaluated Semax as a peptide for menopause, though. More extensive human studies are needed to confirm its effects in healthy adults or during hormonal transitions.

SS-31

SS-31, also known as elamipretide, is studied primarily for its role in mitochondrial function. It binds to cardiolipin, a lipid in the mitochondrial inner membrane, stabilising the membrane structure and supporting more efficient energy production (Elamipretide: A Review of Its Structure, Mechanism of Action, and Therapeutic Potential).

Animal studies have also linked SS-31 to reduced oxidative stress and improved memory and cognitive performance following neuroinflammation, for example in mouse models of memory impairment (Elamipretide (SS-31) improves mitochondrial dysfunction, synaptic and memory impairment induced by lipopolysaccharide in mice). These findings relate to general mitochondrial ageing and inflammation models rather than menopause specifically, so any link to menopause-related fatigue or cognitive changes is a reasonable research question rather than an established finding.

SS-31 may be a promising area of broader mitochondrial and ageing research, but no clinical trials have evaluated it specifically in a menopause context.

NAD+

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme rather than a peptide, but it’s grouped with River Peptides’ other research compounds under the Energy & Metabolic Peptides range, and it’s worth covering here specifically for energy, since that’s the symptom most often linked to it. NAD+ is involved in mitochondrial energy production, DNA repair and the activation of sirtuins, proteins linked to cellular ageing, and levels are known to decline with age.

Research increasingly links this decline to reproductive ageing specifically. In mouse studies, restoring NAD+ using precursor compounds improved oocyte quality and helped restore fertility in older animals (NAD+ Repletion Rescues Female Fertility during Reproductive Aging), and ovarian NAD+ decline has become an active area of research into the biology of menopause itself (Impact of NAD+ metabolism on ovarian aging). This evidence remains largely at the animal and cell-study stage rather than confirmed in human trials, so any link to menopause-related fatigue specifically is a research question rather than an established finding. We offer a range of Energy & Metabolic Peptides.

PT-141

PT-141, also known as bremelanotide, is the one FDA-approved compound on this list, prescribed specifically for hypoactive sexual desire disorder (HSDD) and low libido in premenopausal and perimenopausal women. It’s administered by injection under medical supervision, with reported side effects including nausea and localised skin reactions.

PT-141 sits in a different category to the other compounds covered here: it’s a licensed prescription medicine, not a research compound, and should only ever be used under the direction of a qualified healthcare professional.

BPC-157

BPC-157 is studied for its potential role in tissue repair, joint comfort and gut healing, all relevant to the joint aches and slower recovery many women report during perimenopause, menopause and PCOS. The evidence base and regulatory position for BPC-157 is distinct enough to deserve its own dedicated coverage rather than a summary here. See our Healing & Recovery Peptides range for more detail.

TB-500

TB-500 is studied for similar tissue-repair mechanisms to BPC-157, though through a different pathway involving cell migration and blood vessel formation. As with BPC-157, the fuller picture on TB-500 is covered in the same Healing & Recovery Peptides range.

Weight and body composition changes during menopause and PCOS

Changes in body composition, particularly increased abdominal fat, are a common part of the menopause transition, and weight-related insulin resistance is also a hallmark of PCOS, making this a research area in its own right. Compounds such as CJC-1295, Ipamorelin and Tesamorelin are studied in this context, but the evidence base and regulatory position for weight-related peptides is distinct enough to deserve its own dedicated coverage rather than a summary here. See our Weight Loss Peptides range and Growth Hormone Peptides range for compounds studied for these mechanisms.

Benefits of Sermorelin peptides for women

For women experiencing perimenopause and menopause, Sermorelin is being studied for its potential to support energy, sleep quality, lean muscle tone and skin elasticity. It encourages the body to release its own growth hormone rather than replacing it directly, which preserves natural bodily feedback mechanisms. Sermorelin belongs to the same growth hormone-releasing peptide family covered in more depth in our Growth Hormone Peptides range.

Visceral fat

Sermorelin is being researched for its potential to support reduction of abdominal fat, which menopause can make increasingly difficult to shift, while helping to maintain lean muscle mass.

Bone density

A meta-analysis of growth hormone-deficient adults found that growth hormone replacement therapy was associated with improved bone mineral density (Effects of Growth Hormone Replacement Therapy on Bone Mineral Density in Growth Hormone Deficient Adults: A Meta-Analysis). Since Sermorelin works by prompting the pituitary gland to release more of the body’s own growth hormone, researchers are interested in whether it could offer a similar benefit, though this hasn’t been studied directly in postmenopausal women.

Energy and recovery

Sermorelin is also being studied for its potential to support exercise recovery, reducing fatigue and increasing stamina.

Skin and hair

Sermorelin is thought to support cellular regeneration, which may benefit skin elasticity and hair and nail health.
Sermorelin is available as a prescription medication in some contexts and requires medical evaluation beforehand; any dosing decisions sit with the prescribing doctor rather than the patient. That distinction matters when comparing the compounds in this guide: Sermorelin and PT-141 both require a prescription, while Ipamorelin, Semax, SS-31, BPC-157 and TB-500 remain in earlier-stage research and are not approved for human use.

Best peptides for menopause frequently asked questions

What are the best peptides for menopause?

One of the potential best peptides for menopause is PT-141 (bremelanotide), an FDA-approved prescription treatment for low libido in perimenopausal women with HSDD. PT-141 must only be used as prescribed by a healthcare professional.

Does Sermorelin raise oestrogen levels?

Although Sermorelin doesn’t directly increase oestrogen levels, it’s still studied as a potential peptide for menopause because it stimulates the pituitary gland to naturally produce more human growth hormone and IGF-1.

What are the benefits of Sermorelin peptides for women?

Sermorelin is studied for its potential to support energy, sleep quality, lean muscle tone, skin elasticity and bone density in women going through perimenopause and menopause, largely by encouraging the body to release more of its own growth hormone rather than replacing it directly. This is covered in more depth above, and in our Growth Hormone Peptides range.

What are BPC-157’s benefits for women?

BPC-157 is studied for its potential role in tissue repair, joint comfort and gut healing, which is why some women researching perimenopause and menopause symptoms come across it. The fuller evidence picture on BPC-157 is covered in our Healing & Recovery Peptides range rather than repeated here.

What’s the difference between hormonal axis peptides and growth hormone peptides?

Hormonal axis peptides are studied for their action on pathways like the hypothalamic-pituitary-gonadal axis, which regulates reproductive hormones such as oestrogen and progesterone. Growth hormone peptides, such as Sermorelin and Ipamorelin, work through a different pathway, prompting the pituitary gland to release growth hormone. Both are relevant to menopause research, but for different reasons.

What are peptides for women?

Peptides for women cover several distinct research areas rather than one single thing. Depending on what’s being researched, that can mean compounds studied for menopause, perimenopause or PCOS-related hormonal changes (our Hormonal Axis Peptides range), growth hormone and body composition pathways (our Growth Hormone Peptides range and Weight Loss Peptides range), or tissue repair and recovery (our Healing & Recovery Peptides range). This guide focuses specifically on the compounds most relevant to menopause, perimenopause and PCOS.

What are the best peptides for females?

Within the scope of this guide, the compounds most commonly researched in relation to menopause are Ipamorelin, Semax, SS-31, NAD+, Sermorelin, and PT-141, the one FDA-approved option among them. Evidence quality varies significantly between these, which is why each is covered individually above rather than ranked here.
