Research Peptide FAQ
Plain answers about intended use, sourcing, analytical documentation, ordering, and shipping.
Analytical documentation
How do I request a Certificate of Analysis?
Use the request form on any product page or on the
contact page, or email
support@peptalabs.com. Reports are sent by email and are not downloadable from product pages.
What testing is represented by the report?
The represented independent testing is HPLC purity analysis and mass-spectrometry identity confirmation. Pepta Labs does not claim sterility, endotoxin or LAL, potency, pharmaceutical-grade, cGMP, contaminant-panel or vial fill-quantity testing. Reported purity is shown on each product page. See the
testing and documentation page.
Why does the report not name Pepta Labs?
Products are sourced through a cooperative purchasing arrangement. The purchasing group commissions testing, so the report may name the group or source as the client. Supplier-identifying fields are redacted before sharing.
Shipping and storage
No. Compounds ship as lyophilized powder at ambient temperature without cold packs or insulated packaging. Lyophilized powder is substantially more thermally stable than the same compound in solution, and short-term ambient exposure in transit is not expected to meaningfully change measured purity.
How should unopened vials be stored?
Refrigerate lyophilized powder at 2–8°C on arrival or store at -20°C long term. Keep vials sealed, dry, and protected from light. See the
peptide storage guide.
Ordering
Do I need an account to order?
Yes. Orders are placed from a free account with a confirmed email address, so every order traces back to a real customer. Registration asks for a name, an email address and a password; the confirmation link arrives by email and is valid for 24 hours.
Which payment methods are accepted?
Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.
When does my order ship, and how do I track it?
Most orders ship the next business day. A shipping confirmation with tracking is emailed when the order ships, and your order history is under
My Orders in your account. Processing and delivery times are estimates, not guarantees.
What if a shipment arrives damaged or incorrect?
Inspect the shipment on arrival and email
support@peptalabs.com within seven days of delivery. A verified damaged, incorrect or nonconforming shipment may be replaced or refunded. Unopened items in original sealed condition may be returned within 30 days with return authorization; opened items cannot be returned.
Intended use and sourcing
Are products for human or animal use?
No. Products are intended and offered solely for laboratory research. They are not for human or animal use, consumption, administration, clinical use, diagnosis, or treatment. We do not provide dosing, injection, administration, or reconstitution guidance. See the
research use policy.
Does Pepta Labs manufacture or test the compounds?
No. Pepta Labs is a supplier and reseller, not a manufacturer or testing laboratory. The cooperative purchasing group places volume orders with manufacturers and funds independent HPLC and mass-spectrometry testing.
