Frequently asked questions
Straightforward answers to the questions we hear most, from product quality and storage to ordering and delivery. At Bluewell, transparency is part of our standard, so you can find everything you need to know in one place.
What makes Bluewell Peptides different?
Bluewell is built on one promise, clarity. Proven compounds, verified purity, and consistent batches. Every vial is produced by qualified facilities, documented with lab data, and packaged for protection in transit.
No compromises, no untested formulas, just research-grade peptides you can trust.
Are Bluewell products for human use?
No. All products are supplied strictly for laboratory research use only. They are not for human consumption, medical, or veterinary use.
How are peptides made?
Our peptides are produced via solid-phase peptide synthesis (SPPS), a widely used method that assembles amino acids in precise sequences.
Each batch is purified and verified for identity and purity before release.
Do your peptides contain mannitol or other fillers?
Yes. A small amount of mannitol is included in certain peptides to protect and preserve their quality. Mannitol helps maintain structural stability during freeze-drying, improves solubility for easier reconstitution, and shields the product from excess moisture. It also ensures the powder is visible in the vial and easy to handle during manufacturing.
Do you sell blended peptides?
We offer clearly labeled curated stacks where appropriate. For custom requirements, contact us and we’ll advise what’s possible within compliance.
What’s the difference between peptide purity and peptide yield?
Purity tells you how much of the material is the intended peptide versus trace by-products. Yield is how much peptide is obtained from synthesis. We prioritize high, batch-consistent purity first, then yield.
Do you provide Certificates of Analysis (CoA)?
Yes — we have a Certificate of Analysis for every product and batch we offer. You can view them anytime on our Lab Certificates page.
Do you supply third-party HPLC reports?
Yes. We use HPLC and mass spectrometry as part of our quality program, including third-party verification for selected lots. Results are linked to the batch on the Lab Certificates page.
How are your peptides packaged?
Vials are sealed and lot-coded, then packed in protective materials to maintain integrity during transit. Temperature-sensitive products are shipped with appropriate safeguards.
How do you ensure batch consistency?
We follow controlled SOPs, verify identity and purity for each lot, and only release batches that meet our specification thresholds.
How should I handle and store my peptides?
Store lyophilized peptides in a cool, dry place away from light. For longer-term storage, refrigerate or freeze. Minimize freeze-thaw cycles and follow your lab’s SOPs.
Do you provide reconstitution guidance?
Yes. We include clear guides with first orders and have step-by-step resources available on our website, including our Peptide Calculator and Reconstitution Guide. Use solvents and concentrations appropriate to your experimental design.
What payment methods do you accept?
We accept all major cards, bank transfers and Local delivery with in-person payment is also available around the Manchester UK area.
Is my payment information secure?
Yes. Payments are processed by trusted, PCI-compliant providers. We do not store full card details on our servers.
I just paid for my order — what happens next?
You’ll receive an order confirmation immediately, then a shipping confirmation with tracking once dispatched. You can also view status in your account.
What shipping options do you offer?
We offer tracked domestic and international services. Order by 3pm for next-day options where available. Final options and rates are shown at checkout.
What if there’s an issue with my delivery?
Please notify us within 48 hours of delivery with photos of packaging and contents. We’ll assess and resolve quickly.
What is your returns policy?
For safety and integrity reasons, we can only accept returns of unopened, sealed products within the stated window. Start a request here: Returns.
What are peptides?
Peptides are short chains of amino acids arranged in specific sequences. In research, they’re used to explore pathways, receptors, and targeted mechanisms with high specificity.
How do I choose the right peptide or stack?
Start with your research objective. Review product pages and CoAs for specifications. Our Resources & Guides explain common use-cases and stack logic at a glance.
Can I stack multiple peptides?
Many researchers explore combinations. Keep designs simple, document variables, and adjust one factor at a time for clean data.
