Why Energy and Libido Decline During Perimenopause?

Energy often dips in perimenopause because the body works harder to adjust to changing hormones. Many women notice increased fatigue during the day as sleep becomes lighter, hot flashes disrupt rest, and metabolism slows. Without steady, deep sleep, recharging proves difficult, making daily tasks feel more draining.

At the same time, changes in estrogen and other signaling chemicals affect sexual desire and mood. Vaginal dryness or discomfort reduces interest in intimacy, while stress and anxiety create barriers to connection. These concerns shape ongoing studies on the best peptides for women in perimenopause, as researchers explore how they relate to energy balance and sexual wellness.

With these challenges in mind, researchers investigate several peptides to understand how they may relate to perimenopausal health.

Best Peptides for Women in Perimenopause

When looking at the best peptides for women in perimenopause, researchers are studying several compounds that connect to concerns like fatigue, libido, mood, and recovery. Each has unique functions in the body, and studies continue to explore how they may relate to women’s health during this transition.

Some of the most discussed peptides include:

• Kisspeptin – linked to reproductive hormone signaling.
• PT-141 – studied for its effects on sexual desire.
• Oxytocin – connected to bonding, intimacy, and mood.
• Tesamorelin – explored for body composition and metabolism.
• TB500 – associated with tissue and cell repair.
• GHK-Cu – linked to skin health and cellular renewal.
• Ipamorelin & CJC-1295 stack – of interest for growth hormone release and energy balance.

Among these peptides, some stand out for their potential influence on intimacy and sexual wellness.

Can Kisspeptin Boost Libido During Perimenopause?

Clinical studies show that Kisspeptin can stimulate brain regions linked to arousal and attraction. In trials with women who had low sexual desire, kisspeptin infusion increased activity in areas tied to sexual response. It also led to higher self-reported arousal compared with placebo. Researchers believe these effects come from the way kisspeptin interacts with pathways that control reproductive hormones. It may also influence emotional processing.

Most of the research so far has focused on pre-menopausal women with hypoactive sexual desire disorder (HSDD). Perimenopausal women have not been studied directly. Even so, the findings are still relevant because many also experience a drop in libido. This link explains why kisspeptin is often included in discussions of the best peptides for women in perimenopause, especially in relation to sexual wellness.

Kisspeptin acts through reproductive hormone signaling, while another peptide, PT-141, influences sexual desire through brain pathways and offers a different angle on intimacy in perimenopause.

Does PT-141 Really Increase Libido in Women?

PT-141 (Bremelanotide) increases libido in premenopausal women with hypoactive sexual desire disorder (HSDD). It activates melanocortin receptors (primarily MC4R) in the brain rather than altering hormone levels. In Phase 3 RECONNECT trials, these women reported higher sexual desire scores (FSFI-D +0.30–0.42 vs placebo, p<0.001). They also felt less distress compared to those taking a placebo.

Clinical studies focused only on premenopausal HSDD groups. However, PT-141 still appears among the best peptides for women in perimenopause in sexual health research. This interest stems from its unique brain-based mechanism. Because researchers have not yet run controlled trials on perimenopausal women, its use for this group remains investigational.

Intimacy is only one part of the perimenopause experience. Mood shifts, emotional bonds, and comfort also play key roles. These factors bring oxytocin into focus.

Oxytocin in Perimenopause: Beyond the Bonding Hormone

Oxytocin is a natural peptide often called the “bonding hormone” because it supports trust, closeness, and emotional connection. Researchers also link it to sexual response. Oxytocin levels rise during arousal and peak at orgasm. In perimenopause, when intimacy and mood shift, oxytocin has become a focus of several studies.

Clinical trials using intranasal oxytocin sprays in women did not show improvements in sexual function beyond placebo effects. However, smaller studies suggest vaginal oxytocin gels may ease dryness and improve comfort during intimacy. Neither form is proven specifically for perimenopause desire.

Beyond intimacy and mood, weight gain and metabolism are also pressing concerns during perimenopause.

Can Tesamorelin Help With Abdominal Fat in Perimenopause?

Tesamorelin reduces abdominal fat by stimulating growth hormone secretion. It was first studied for its ability to reduce abdominal fat in HIV-related lipodystrophy, where clinical trials showed significant reductions in visceral fat. Research has since looked at its effects on metabolism, fat distribution, and muscle preservation primarily within HIV populations.

In perimenopause, weight gain around the midsection is a common challenge. While Tesamorelin has not been specifically studied or approved for this stage, findings from existing research indicate it influences growth hormone pathways involved in fat metabolism. However, its effects remain unproven in perimenopausal women.

Beyond metabolism, perimenopause affects how the body heals and recovers. Slower recovery, joint stiffness, and muscle discomfort are common, which is where TB500, a peptide linked to tissue repair, comes into play.

Explore Tesamorelin from Peptide Works, a synthetic peptide that triggers growth hormone release and has been examined for its effects on abdominal fat.

Can TB500 Support Healing and Tissue Repair?

TB500 supports healing and tissue repair through cell migration and wound healing in preclinical models. Research shows it plays a role in regulating inflammation during recovery processes.

During perimenopause, many women notice slower recovery from exercise and more frequent joint or muscle discomfort. Preclinical mechanisms generate research interest for TB500 as one of the best peptides for women in perimenopause, being studied for tissue support.

Beyond recovery and joint health, many women also focus on visible changes to skin and hair during perimenopause. Preclinical research links GHK-Cu to regeneration and collagen support.

GHK-Cu Peptide and Skin Health in Perimenopause

GHK-Cu peptide effectively supports skin health by boosting collagen production and skin elasticity. Research links this copper-binding peptide to skin repair, antioxidant activity, and wound healing. Studies also associate it with reduced fine lines and potential support for hair growth through its role in regenerative and anti-inflammatory pathways.

During perimenopause, falling estrogen levels cause skin to thin, dry out, and heal more slowly. Although researchers have not studied GHK-Cu directly in this stage, its regenerative effects make it a key peptide of interest for midlife skin support.

While GHK-Cu supports skin health, some of the best peptides for women in perimenopause are discussed for energy, sleep, and recovery. Ipamorelin and CJC-1295 often fill this role by supporting growth hormone signaling in research.

Ipamorelin & CJC-1295: Growth Hormone Support in Perimenopause

Ipamorelin and CJC-1295 are peptides often studied together because they stimulate the release of growth hormone. Ipamorelin works as a selective secretagogue, while CJC-1295 is an analogue of growth hormone–releasing hormone (GHRH). Research shows that in combination, they can raise growth hormone and IGF-1 levels more effectively than either peptide alone.

In perimenopause, growth hormone levels decline, which may influence energy, sleep, and body composition. For this reason, the Ipamorelin & CJC-1295 stack is frequently mentioned among the best peptides for women in perimenopause, especially in research exploring recovery, metabolism, and overall vitality.

Because researchers study so many different options, comparing the best peptides for women in perimenopause side by side helps clarify how each one may address specific needs.
