Common Questions
Frequently asked.
What purity level are your peptides and how is it verified?▾
Our research peptides are supplied at ≥99% purity (HPLC) unless otherwise noted on the product page. Every batch is verified by an independent third-party laboratory (such as Janoshik Analytical) — HPLC for purity and mass spectrometry for identity — and a batch-specific Certificate of Analysis is available for each lot.
What is a Certificate of Analysis (COA) and how do I read it?▾
A COA is the third-party lab report documenting a batch’s identity and purity. It lists the compound tested, the measured purity percentage (by HPLC), and confirmation of molecular mass (by MS). To get the COA for your specific batch, visit our Certificates of Analysis page or email support@specoplabs.com with your order number.
How should I store the lyophilized product?▾
Store lyophilized (freeze-dried) vials at -20°C, protected from light. Once reconstituted in a laboratory setting, follow standard cold-chain practice and your institution’s handling protocols.
How long is the lyophilized product stable?▾
Stored correctly at -20°C and protected from light, lyophilized peptides remain stable for extended periods (typically 24+ months). Once reconstituted, use within the window appropriate for the specific compound and keep refrigerated.
How fast do you ship and is cold shipping required?▾
Orders are typically processed within 1–2 business days and ship discreetly in plain packaging, with free US domestic shipping on orders over $250. Lyophilized peptides are stable at ambient temperature for the short transit window, so specialized cold shipping is not required.
Are these peptides for human use?▾
No. All products are sold strictly for laboratory and in-vitro research use only (RUO). They are not drugs, supplements, or medical products, and are not for human or animal consumption, diagnosis, or treatment.
What is your return and refund policy?▾
Because of the nature of research materials, returns are handled per our Refund & Return Policy. If there’s any issue with your order, email support@specoplabs.com right away and we’ll make it right.
