For Research Use Only, or RUO, means the product is supplied solely for laboratory research and analytical applications. Honest Peptide products are not approved for human or animal administration, therapeutic use, diagnosis, or treatment.

No. Honest Peptide products are laboratory research materials and are not prescription medicines.

Unless otherwise stated on the product page, our peptides are supplied in lyophilized (freeze-dried) form. Lyophilization removes water from the material to improve stability during storage and transportation. Depending on the compound and manufacturing process, the material may appear as a cake, powder, film, or other dried form. Differences in physical appearance do not necessarily indicate a difference in identity or purity.

Our testing program uses independent third-party analytical laboratories to verify product identity, purity, peptide content, and other quality characteristics. Testing may include:

1. Mass Spectrometry (MS) — verifies molecular identity.
2. High-Performance Liquid Chromatography (HPLC) — measures peptide purity.
3. Net Peptide Content — measures the amount of peptide present in the tested material.
4. Heavy Metals Testing (ICP-MS) — screens for specified elemental contaminants such as lead, arsenic, cadmium, and mercury.
5. Fentanyl Screening (LC-MS/MS) — tests for the presence of fentanyl as a potential contaminant.
6. Endotoxin Testing (Bacterial Endotoxin / LAL Assay) — Endotoxins are inflammatory compounds, also known as lipopolysaccharides (LPS). This testing checks that endotoxin levels are within the laboratory’s specified limits.

The tests performed for a particular batch are shown on its applicable Certificate of Analysis or laboratory report, which can be found on the relevant product page or in our COA Library.

Every Honest Peptide batch must meet our release specifications before it is made available for sale:

• Identity: The peptide must be confirmed as the expected compound by mass spectrometry.
• Purity: Minimum 99% HPLC purity.
• Peptide content: The measured peptide content must be within 10% of the stated amount on the vial. Overfill is acceptable.
• Contaminants: The batch must pass all applicable contaminant testing, with no tested contaminants detected above the laboratory’s specified limits.

The applicable analytical results are published in the batch-specific COA or laboratory report.

A Certificate of Analysis is a laboratory report documenting the analytical results for a tested batch. You can view the latest available COA directly on the applicable product page or browse our COA Library.

Yes. COAs correspond to the tested batch or lot identified on the report.

Each production batch is assigned a batch or lot identifier corresponding to its analytical documentation. Use the identifying information associated with your product to locate the relevant report in our COA Library or on the applicable product page.

Yes. We publish testing for every batch ever sold. Previous batch testing is retained in our COA Library so that historical analytical results can also be reviewed.

Testing is conducted by independent third-party analytical laboratories rather than relying solely on manufacturer-issued documentation.The laboratory responsible for a particular analysis is identified on the applicable test report.

Yes. Volume discounts are offered on our products and displayed on the applicable product page. Qualifying discounts are automatically reflected in your cart. For larger or wholesale orders, please contact hello@honestpeptide.com.

Once your order has been successfully submitted, you will receive an order confirmation by email. For certain payment methods, confirmation may be sent once payment has been verified.

Yes. Orders of $120 or more qualify for free shipping automatically at checkout.

We’ll email you tracking information as soon as your shipment has been processed by the carrier. If your tracking has not been updated for an extended period, contact hello@honestpeptide.com and we’ll help investigate.

Lyophilization significantly improves peptide stability during storage and transportation. Brief exposure to normal shipping temperatures generally does not compromise sealed lyophilized material. Stability can vary by compound and conditions, however. If your shipment experiences an extended delay, extreme temperatures, or arrives damaged, contact us with your order number.

Email hello@honestpeptide.com with:

• Your order number
• A brief description of the issue
• Photos of the product and packaging, when relevant

Our team will review the issue and help resolve it.

Contact hello@honestpeptide.com with your order number and photos of the shipment. We’ll review the issue and arrange a resolution.

Peptide stability depends on the compound and storage conditions, including temperature, moisture, light exposure, and handling. Refer to the applicable product documentation for storage guidance rather than treating a single shelf-life estimate as applicable to every peptide.
