Frequently Asked Questions
What are research peptides?
Peptides are short chains of amino acids joined by peptide bonds, either occurring naturally in the body or prepared synthetically. Research applications include connective tissue repair, inflammation modulation, neuroprotection, endocrine signalling, and metabolic regulation.
Are your products intended for human consumption?
No. Every product sold on this site is supplied strictly for laboratory research and development. Nothing offered here is intended for human, veterinary, or household use.
How are your products manufactured?
Our catalog is produced by automated solid-phase peptide synthesis (SPPS) and finished with freeze-drying (lyophilization). Automating the coupling and deprotection cycles is what gives consistent sequence fidelity between production runs.
How are your products tested?
Every production batch undergoes high-performance liquid chromatography (HPLC) purity analysis and liquid chromatography-mass spectrometry (LC-MS) quality confirmation. HPLC quantifies how much of the sample is the target compound; LC-MS confirms the molecular mass matches the intended sequence.
Why do you run both HPLC and LC-MS?
Purity alone cannot tell you that the species present is the sequence you ordered. A truncated or deletion sequence can still return a high purity figure. LC-MS closes that gap by confirming molecular mass.
What is a lot-specific certificate of analysis?
It is a certificate issued against one production lot and tied to the lot number printed on your vial. A certificate from a different batch tells you nothing about the material in your hand, so we never substitute a generic reference document.
What form do your products ship in?
All peptides ship as lyophilized powder in sealed glass vials. We do not supply pre-dissolved liquid formulations or bulk loose powder.
Do I need to reconstitute the vials?
Yes. Lyophilized peptides must be reconstituted before laboratory use. Most dissolve in bacteriostatic water; a small number require a mildly acidic solvent, which is noted on the individual product page.
What solvent should I use?
Bacteriostatic water containing 0.9% benzyl alcohol is the default for most sequences and permits multiple withdrawals. Preservative-free sterile water suits assays where benzyl alcohol would interfere. Tesamorelin and similar sequences require 0.6% acetic acid solution.
Do you sell reconstitution solvents?
Yes. Bacteriostatic water, sterile water for injection, and 0.6% acetic acid solution are available on the solvents page. They are sold separately from the peptide vials.
How should I store lyophilized peptides?
Store unreconstituted vials in a freezer, shielded from light. After reconstitution, keep vials refrigerated at 2-8 degrees C and protect from light. Avoid repeated freeze-thaw cycling.
How long is a reconstituted vial stable?
Stability depends on the sequence and the solvent used. Bacteriostatic water permits multiple withdrawals over a longer window than preservative-free water, which should be treated as single-use.
Why is a reported purity at or above 100%?
Purity is measured against a reference standard that itself carries a minimum specification. A value at or above 100% means the sample assayed at or higher than that reference standard.
Where can I find current purity information?
Verified current-batch purity values are not published in this website project. Request the available lot documentation through the COA Library or WhatsApp before procurement.
How do I place an order?
Add items to your inquiry list and send it over WhatsApp. We reply with availability, the lot certificate, and a shipping quote for your destination. This site does not process online payments.
Do you ship internationally?
Yes. We distribute globally to academic researchers, institutional laboratories, and independent scientists. International customers are responsible for compliance with their local import regulations.
How are wholesale orders quoted?
Message us with the product names, specifications, quantities, and destination country. We will confirm availability and provide a written quotation.
Can you provide extra documentation for procurement?
Yes. If your institution requires documentation beyond the standard certificate, mention it in your first message so we can prepare it alongside the quote.
Do you sell to individuals or only institutions?
We supply research institutions, laboratories, and qualified independent researchers. All purchases are for laboratory research use only.
Do you have an affiliate program?
Yes. You can register through the affiliate area and track referrals from your affiliate dashboard.
