Frequently Asked Questions

Peptides are short chains of amino acids that act as building blocks of proteins.

Yes. U.S. companies may sell peptides if they are clearly labeled “For Research Use Only. Not for human or diagnostic use.” Under the Federal Food, Drug, and Cosmetic Act (21 U.S.C. §321(g)(1)), a product is considered a “drug” only if it is intended for human or animal use. If labeling and promotion remain strictly for research use, the FDA does not regulate them as drugs.

As a research facility, it is your responsibility to check and comply with all local and regional laws in your area regarding the purchase and use of these materials.

Usage instructions cannot be provided by Biotech Compounds as all of our products are for research and testing. Despite that, all of our products are guaranteed for purity and identification.

Our peptides are intended for research purposes only and are not for human consumption. Our peptides are tested for quality and purity and meet the standard for usage.

Peptides should be stored in a cool, dry place away from direct sunlight. Some peptides may require refrigeration.

We aim to get your order out as quickly as possible. Orders that are currently not in a state of biosynthesis, usually ship the next business day.

We ship packages based upon your location and tracking numbers are provided once shipped.

Please note that while we do our best to ensure timely delivery, unexpected delays such as severe weather or carrier issues may impact transit times. As a result, delivery times vary based on location and shipping provider.

Yes, we ship to many countries worldwide. Please note that international shipping times may vary, and additional customs fees may apply depending on your country's regulations.

We accept various payment methods, including major credit cards (Visa, MasterCard, American Express) via PayPal, BTC, ETH, and ADA.

High-Performance Liquid Chromatography (HPLC) is an analytical technique that separates, identifies, and quantifies each component in a peptide sample. It is the industry-standard method for determining peptide purity because it can detect impurities at very low concentrations.

When a peptide undergoes HPLC testing, the sample is dissolved and passed through a column under high pressure. Each component elutes at a different time, producing a chromatogram that shows the relative abundance of the target peptide versus any contaminants. A purity reading of 98% or higher is generally considered research-grade. All Biotech Compounds products are tested using HPLC, and results are documented in each product's Certificate of Analysis.

A Certificate of Analysis (COA) is an official document issued by a testing laboratory that reports the results of quality-control tests performed on a specific batch of product. It typically includes purity percentage, molecular weight confirmation, batch number, and the testing methods used.

COAs provide transparency and allow researchers to verify that the materials they receive meet the specifications listed on the product label. Biotech Compounds publishes COAs for all products, which can be viewed and downloaded from our COA hub.

Biotech Compounds peptides are manufactured to a minimum purity of 98%, with most products exceeding 99% purity as verified by independent HPLC and mass spectrometry analysis. Batch-specific purity data is available on each product's Certificate of Analysis.

We partner with Chromate, an independent third-party laboratory, and encourage customers to conduct their own verification testing. Purity results for individual batches can be found on our Certificates of Analysis page.

Lyophilized (freeze-dried) peptides should be stored at -20°C or colder in a sealed container protected from moisture and light. Under these conditions, most peptides remain stable for 12 months or longer. Reconstituted peptides should be refrigerated at 2-8°C and used within 4-6 weeks.

Reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide powder into a liquid solution using bacteriostatic water or another appropriate solvent. This step is necessary before the peptide can be accurately measured and used in research applications.

Lyophilized peptides are in a dry, freeze-dried powder form as shipped. Reconstituted peptides have been dissolved into a liquid solution using bacteriostatic water. Lyophilized peptides have a longer shelf life and greater stability, while reconstituted peptides are ready for immediate use but must be refrigerated.

"For Research Use Only" (RUO) means the product is intended exclusively for laboratory research, scientific investigation, and educational purposes. RUO products are not approved for human or animal consumption, diagnostic procedures, or therapeutic applications.

This designation is consistent with FDA labeling guidelines under 21 CFR §809.10. Researchers are responsible for complying with all applicable regulations. For full details, see our Terms of Use.

Yes. Biotech Compounds publishes Certificates of Analysis for all products, organized by product name and batch number. You can search for your specific batch on our COA page to view HPLC purity data, mass spectrometry results, and other quality metrics.

Visit our Certificates of Analysis page and use the search function to find your product by name or batch number. If you cannot locate your COA, contact our support team for assistance.
