Frequently Asked Questions
Peptides FAQ - Product & Quality
What does “Research Use Only” (RUO) mean?
RUO products are not for human or veterinary use, diagnostics, or drugs. They’re sold solely for laboratory, in-vitro, and R&D applications.
Are your peptides sterile?
Lyophilized powders are produced under clean conditions but are not guaranteed sterile. If sterility is required for your application, use appropriate sterile technique and filtration in your lab.
What purity are your peptides?
Purity varies by product and batch and is typically specified on each product page. A Certificate of Analysis (CoA) reflects HPLC purity for the lot you receive.
Do you provide Certificates of Analysis (CoA)?
Yes. Each lot includes a CoA with identity and purity data (e.g. HPLC/LC-MS), listed on both our product pages and quality page. Request via support with your order # if not included.
Are your products free of antibiotics/allergens?
Products are synthesized chemicals, not food items. We do not intentionally add common allergens; however, no allergen-free guarantee is provided.
Are your peptides animal-free/vegan?
They are chemically synthesized (no animal tissue), but we do not certify vegan status.
Do you sell premixed solutions?
Most products ship lyophilized. If a solution is offered, it will be clearly labeled and include solvent details.
Do you provide MSDS/SDS?
Yes. Safety Data Sheets are available on request for each product.
Are your peptides GMP-grade?
Unless explicitly stated, products are research-grade, not GMP pharmaceutical grade.
What analytical tests do you run?
Typically HPLC for purity and LC-MS or MS for identity. Some lots may include additional tests (water content, TFA content, endotoxin) where noted.
Are there additives or excipients?
Many lyophilized peptides include mannitol or similar bulking agents; see product page/CoA for details.
What does “lyophilized” mean?
Freeze-dried powder form that improves stability and shelf life under proper storage.
What’s the typical vial size/fill?
See each product page for mass (e.g., 5 mg, 10 mg). Vial fill volume is not indicative of mass—refer to the labeled content.
Peptides FAQ - Handling & Storage of Peptides
How should I store lyophilized peptides?
Keep sealed and dry. Short term: 2–8 °C (refrigerated). Long term: −20 °C is recommended.
Can I freeze and thaw repeatedly?
Avoid repeated freeze–thaw cycles. Aliquot after reconstitution if needed.
How long do peptides last after reconstitution?
Stability depends on sequence, solvent, pH, and temperature. In general, keep cold, minimize time in solution, and consult literature for your specific peptide.
What solvent should I use to reconstitute?
Use a suitable lab-grade solvent compatible with your application and peptide solubility (e.g., sterile water, dilute acid/base, or buffer). We do not provide usage or dosing guidance.
Why doesn’t my peptide dissolve?
Hydrophobic sequences may require a small amount of organic solvent (e.g., acetonitrile) before diluting with aqueous buffer. Check literature and handle in a chemical hood.
What does “store desiccated” mean?
Minimize moisture exposure. Keep vials sealed with desiccant in cold storage.
Peptides FAQ - Ordering & Payment
How long will it take for my order to ship after processing?
Our team always ships orders within 1 business day if there are no unexpected delays with our facility or shipping providers.
What shipping providers will my order be shipped through?
Our team ships all orders through USPS or UPS.
How do I properly pay with zelle?
When placing your order, you will be provided with an order # alongside Zelle recipient details. You must send your Zelle payment with your order # noted in the message/comment section of the transaction. Once sent, screenshot your payment confirmation and continue on the order page to upload as proof of payment. Once our team confirms payment, your order will be promptly fulfilled.
I wasn't able to screenshot my Zelle Payment Confirmation, how can I upload proof of payment?
If you noted your order # in the the comment/message section of the transaction, our team will still be able to manually confirm the transaction. In the meantime, you can upload a screenshot of the payment in your recent transactions.
