Question 1

What purity standard do your peptides meet?

Accepted Answer

Every production lot is independently verified to exceed 99% purity through reversed-phase HPLC with UV detection at 214 nm or 220 nm. The reported purity percentage reflects the target peak area relative to all detected peaks. Full analytical data — including the chromatogram — is published directly on each product page before you order.

Question 2

Who performs the analytical testing?

Accepted Answer

All testing is conducted by independent, accredited laboratories within the United States. Axos Research Inc maintains complete separation between production and verification — we never test our own materials. Each lot undergoes HPLC for purity and ESI-MS for molecular identity confirmation, with results documented in a lot-specific Certificate of Analysis.

Question 3

What documentation is published for each product?

Accepted Answer

Every product page includes a current, dated Certificate of Analysis listing purity, molecular weight, appearance, and methodology. It also includes the full HPLC chromatogram, mass spectrometry identity data, and applicable storage recommendations. The lot number on your vial label corresponds exactly to the published analytical data — complete traceability from order to lab bench.

Question 4

How do you maintain consistency between production lots?

Accepted Answer

Each lot is synthesized using standardized solid-phase peptide synthesis protocols and purified via preparative HPLC under optimized conditions. Every lot must meet defined acceptance criteria for purity (≥99% by HPLC), identity (confirmed by MS), and physical appearance before release. Lots that fall below specification are rejected outright — not reworked, blended, or shipped.

Question 5

How do I find the Certificate of Analysis for my lot?

Accepted Answer

Every lot's Certificate of Analysis is published in our COA Library. Enter the lot number printed on your vial to pull the exact certificate for your order — purity, molecular weight, HPLC chromatogram, and mass-spec identity, all matched to what shipped.

Question 6

How quickly do orders ship?

Accepted Answer

Orders placed before 2:00 PM EST on business days are dispatched the same day. We maintain ready inventory of all catalog items to eliminate production delays. A tracking number is emailed once your shipment is processed.

Question 7

What shipping methods are available?

Accepted Answer

We offer USPS First Class (3–5 business days), USPS Priority Mail (2–3 business days), and USPS Priority Mail Express (1–2 business days). All peptides ship as lyophilized powders, which are stable at ambient temperature during transit. Transfer to recommended storage (−20°C or colder) upon receipt.

Question 8

How do I track my order?

Accepted Answer

A tracking number is emailed the moment your order is dispatched. You can also check live status any time from your account.

Question 9

Do you ship internationally?

Accepted Answer

At this time, Axos Research Inc ships exclusively within the United States. Orders with international shipping addresses cannot be fulfilled; if one is placed, it is cancelled before dispatch and any payment is refunded in full. We do not ship to freight forwarders, mail forwarding services, or APO/FPO/DPO addresses.

Question 10

What payment methods do you accept?

Accepted Answer

Checkout runs on a secure, encrypted payment page. We accept major credit and debit cards; your card details are processed by our payment provider and never touch our servers.

Question 11

What is your refund and cancellation policy?

Accepted Answer

Research materials are sold on a final-sale basis — we don't accept returns or offer refunds for change of mind. The sole exception is our off-specification refund: if independent, third-party laboratory testing shows a product falls below its stated purity or is otherwise off-specification, we refund that order in full. Products that arrive damaged, defective, or incorrect are replaced or, at your option, refunded — report them within 7 days of delivery with photos. Orders can be cancelled for a full refund any time before dispatch.

Question 12

How should lyophilized peptides be stored?

Accepted Answer

Store lyophilized peptides at −20°C or colder in their original sealed vials. For storage exceeding six months, −80°C is recommended. Keep vials in a desiccated environment, protect from light, and avoid repeated temperature cycling. Sequence-dependent storage notes are included in each COA where applicable.

Question 13

What shelf life can I expect?

Accepted Answer

Properly stored lyophilized peptides (sealed, −20°C) typically remain stable for 24–36 months from manufacture. Sequences containing oxidation-sensitive residues such as methionine, cysteine, or tryptophan may have shorter effective shelf lives. Specific retest or expiration dates are noted on the COA for each lot.

Question 14

How should reconstituted peptides be handled?

Accepted Answer

Store reconstituted material at 2–8°C and use within 14–21 days. Avoid repeated freeze-thaw cycles. For longer storage, aliquot into single-use volumes and freeze at −20°C. Use sterile technique and a documented reconstitution solution intended for laboratory use, selected against the material's solubility profile.

Question 15

What are your products intended for?

Accepted Answer

All Axos Research Inc products are intended exclusively for legitimate in-vitro laboratory research by qualified professionals. Appropriate uses include in-vitro experimentation, assay development, analytical method validation, and academic or institutional research. Our products are not for human consumption, veterinary use, clinical application, drug compounding, or dietary supplementation.

Question 16

Are your products FDA approved?

Accepted Answer

No. Our products have not been evaluated or approved by the FDA for any purpose. They are research chemicals and laboratory reagents — not drugs, medications, dietary supplements, food additives, cosmetics, or medical devices. They are not intended to diagnose, treat, cure, or prevent any disease.
