Frequently Asked Questions

Everything you need to know about our products, testing, and shipping.

Products & Research

Yes, strictly. All products sold by Sheer Peptides are for in-vitro laboratory research use only. They are not intended for human or veterinary use, consumption, clinical trials, or diagnostic purposes. We enforce this without exception.

All products are synthesised to >99% purity, confirmed by HPLC analysis at an independent ISO 17025 accredited US laboratory. This is not self-reported — an external lab independently verifies every batch before we release it.

Lyophilised peptides should be stored at −20°C in a dry environment away from light and moisture. Reconstituted peptides should be refrigerated at 4°C and used within the recommended timeframe. Avoid repeated freeze-thaw cycles as this degrades purity.

Yes — every product ships with a batch-specific COA from our independent ISO 17025 accredited US laboratory. COAs are also permanently available on each product page. No request needed — full transparency, always. COAs confirm purity (HPLC), molecular weight (MS), endotoxins (LAL), heavy metals, and sterility.

All peptides are supplied as lyophilised (freeze-dried) powder sealed under inert gas. Some products are also available in capsule form. The form is clearly indicated on each product page.

Testing & Quality

We use an independent ISO 17025 accredited US laboratory — not an internal lab, not an affiliate. The laboratory tests each batch for purity (HPLC), molecular weight (MS), endotoxins (LAL assay), heavy metals, and sterility. We have no influence over their results.

All peptides are synthesised at our USA-based cGMP facility using solid-phase peptide synthesis (SPPS). Raw materials are sourced from verified pharmaceutical-grade suppliers and every incoming lot is tested before entering the synthesis pipeline.

Every current batch COA is linked on the product page. If you need a COA for a historical batch included in a previous order, contact us with your order number and we'll provide it immediately.

Ordering & Shipping

Orders placed before 3PM EST ship the same business day via FedEx 2-Day Air. Orders placed after 3PM EST dispatch the following business day. All shipments are fully tracked and insured. Products are shipped from our US facility with appropriate cold-chain packaging where required.

Yes — volume pricing is automatically applied at checkout and scales with quantity. For institutional, research group, or large bulk orders, contact us directly and we will put together a tailored quote.

We accept all major credit and debit cards via our secure payment gateway. All transactions are SSL encrypted. We do not store card details.

Due to the nature of research chemicals, all sales are final. If you receive a damaged, incorrect, or compromised product please contact us within 48 hours of delivery with your order number and photos and we will resolve it immediately. See our full Refund Policy for details.
