Frequently Asked Questions

Peptides are short chains of amino acids — the building blocks of proteins. At The Renewal Lab, we use bioactive peptides that act as cellular messengers: signalling your body to produce more collagen, regulate hormones, repair tissue, or enhance energy metabolism. Unlike many wellness products, peptides work at the molecular level to produce measurable biological changes.

Yes — and female safety and efficacy is central to how we formulate. Every compound in our range has been reviewed for interaction with female hormonal biology, including oestrogen and progesterone cycles. We provide dosing guidance that accounts for cycle phase where relevant, and all products are third-party tested before sale.

Our products are sold for research and wellness purposes. Some peptides may be regulated differently depending on your country or state. We recommend reviewing your local regulations and consulting with a healthcare practitioner familiar with peptide therapy before starting any protocol.

All products are manufactured in GMP-certified (Good Manufacturing Practice) facilities. Every batch undergoes independent third-party testing for purity, identity, and potency. Certificates of Analysis are available on request for any product in our range.

Lyophilised (freeze-dried) peptides should be stored in a cool, dry place away from direct light — ideally in a refrigerator at 2–8°C. Once reconstituted, peptides should be kept refrigerated and used within the timeframe specified on the product label. Never freeze reconstituted peptides.

We ship Australia-wide with express and standard options available at checkout. International shipping is available to select countries — please check availability at checkout. All orders are shipped in temperature-controlled packaging to protect product integrity.

Many of our compounds are designed to work synergistically. However, combining peptides requires care — particularly around dosing frequency and timing. We provide stacking guidance in each product's detailed page and recommend starting with one compound before layering additional protocols.

Due to the nature of our products, we do not accept returns on opened items. If your order arrives damaged or defective, contact us within 48 hours of delivery with photographic evidence and we will arrange a replacement or refund.

This varies significantly by compound and individual. Peptides that act on skin (GKK-Cu, Ret, Epi Skin) typically show visible improvements over 4–8 weeks of consistent use. Systemic peptides like NAD and Slank may produce perceptible changes in energy and body composition within 2–4 weeks. For cellular longevity effects, benefits accumulate over months of consistent use.

We collaborate with independent researchers, peptide scientists, and integrative medicine practitioners in formulating and reviewing our products. However, The Renewal Lab does not provide medical advice. We always recommend working with a qualified healthcare professional before beginning any peptide protocol.
