The Peptides Every High-Performing Woman Should Know

How to optimise healing, energy, cognitive function, and sleep using evidence-backed peptides

For women navigating midlife, hormonal transitions, or the demands of a high-performance lifestyle, supporting your body at the cellular level is essential. Peptides are emerging as powerful tools that enhance natural repair processes, improve cognition, regulate sleep, and even slow biological ageing.

In this guide, you’ll learn what peptides are, how they work, and which ones are especially beneficial for ambitious women looking to thrive—physically and mentally.

What Are Peptides?

Peptides are short chains of amino acids that act as signalling molecules in the body. They help regulate key physiological processes including tissue regeneration, inflammation control, hormone balance, sleep cycles, and brain function.

Unlike synthetic medications that override biological systems, peptides work with your body’s own communication pathways. Most peptides are identical or very similar to naturally occurring ones and are generally well tolerated when used responsibly.

Current research supports the potential of peptides in:

• Healing and recovery

• Gut and skin regeneration

• Neuroprotection and cognitive support

• Hormonal rhythm stabilisation

• Deep sleep enhancement

• Ageing and telomere maintenance

The peptides outlined below are among the most relevant for high-functioning women during transitional or demanding phases of life.

BPC-157: The Regeneration Peptide

Best for: Injury recovery, gut healing, and post-exercise inflammation

BPC-157 is a synthetic peptide derived from a protective protein found in gastric juice. It has shown significant promise in preclinical studies for healing various tissues.

Evidence-based benefits include:

• Promoting blood vessel formation to deliver nutrients and oxygen

• Accelerating the healing of tendons, ligaments, and gut lining

• Reducing inflammation and oxidative damage

• Supporting growth hormone signalling

While human clinical data are limited, BPC-157 has been widely used in regenerative protocols for injury recovery and gastrointestinal support.

Use tip: Consider evening administration to align with the body’s natural repair cycle.

GHK-Cu: The Skin and Gut Rejuvenator

Best for: Collagen loss, skin ageing, and gut lining repair

GHK-Cu (copper peptide) is a naturally occurring molecule involved in wound healing, tissue regeneration, and inflammation control. Its levels decline with age.

Proven and proposed benefits include:

• Stimulating collagen and elastin production

• Enhancing stem cell activity and gene expression for repair

• Improving skin elasticity, firmness, and texture

• Strengthening the gut barrier (“inner skin”)

GHK-Cu is especially beneficial for perimenopausal and menopausal women experiencing changes in skin texture or increased gut sensitivity. It is used topically or systemically depending on the application.

Cerebrolysin: The Cognitive Enhancer

Best for: Brain fog, stress recovery, memory, and focus

Cerebrolysin is a neuropeptide compound that has been studied for decades in Europe and Asia for its effects on brain health. It is commonly used in the clinical management of stroke, dementia, and traumatic brain injury.

Evidence-backed benefits:

• Supports neuroplasticity and neuron survival

• Enhances production of brain-derived neurotrophic factor (BDNF)

• Improves learning, memory, and cognitive speed

• Protects brain tissue from oxidative and inflammatory damage

Although Cerebrolysin requires prescription and injection, it may be a valuable intervention for women experiencing cognitive decline or burnout. It is typically administered under professional supervision.

Epithalon: The Longevity and Sleep Rhythm Regulator

Best for: Ageing support, melatonin balance, and circadian regulation

Epithalon (also spelled Epitalon) is a synthetic peptide that mimics the pineal gland’s natural secretion involved in sleep and ageing regulation.

Studies suggest the following benefits:

• May stimulate telomerase activity, increasing telomere length

• Regulates melatonin production and supports natural sleep rhythms

• Enhances cellular repair and immune response

• May help normalise sex hormone production during midlife

Though much of the data comes from animal research, Epithalon has drawn attention as a promising tool for healthy ageing, particularly when used in cyclical protocols.

DSIP: Delta Sleep-Inducing Peptide

Best for: Improving deep sleep, stress-related insomnia, and recovery

DSIP is a neuropeptide that helps modulate the sleep-wake cycle. It is of particular interest for women who experience disrupted sleep due to hormonal changes or chronic stress.

Potential benefits include:

• Shortening the time it takes to fall asleep

• Increasing time spent in deep, restorative sleep

• Balancing cortisol and other stress hormones

• Supporting overnight tissue repair and immune modulation

While the scientific community continues to explore its exact mechanisms, DSIP shows promise for improving sleep quality and overall recovery.
