Frequently Asked Questions (FAQs)

At Power Peptides, we prioritize uncompromising quality, innovative approaches, and customer-centric solutions. Our proprietary process ensures superior purity and consistency, empowering researchers to achieve groundbreaking results. We collaborate with globally recognized research chemical manufacturers to offer premium quality at affordable prices.

We meticulously craft our peptides to meet the most stringent requirements. Every peptide undergoes extensive in-house evaluation and third-party laboratory analysis using advanced techniques such as NMR, FTIR, Polarimetry, HPLC, and LC-MS analysis. Certificates for each peptide's testing results are available on our website.

We offer various shipping options, including FREE shipping on orders over $200.00 (Grand Total), USPS Priority, FedEx 2 Day, FedEx Overnight, FedEx Overnight with Signature Required, and FedEx Saturday Delivery for orders placed on Fridays before 11am CST. Orders placed and processed before 11am CST Monday through Friday typically ship the same business day.

Yes, we accept orders from around the globe and strive to ensure successful delivery. However, when using a mail forwarding service, we cannot guarantee delivery to the forwarded address, as it is beyond our control.

Due to the perishable nature of our products and to maintain our high quality standards, we are unable to accept returns. However, in the unlikely event of receiving missing, incorrect, or damaged items, please contact us at [email protected] or via WhatsApp at +1 (646) 630-7291 within 7 days of the delivery date for assistance.

When you place your order, you'll receive an email with the tracking number once your order is shipped. We recommend registering an account during checkout for easy order tracking, updating account information, and accessing past orders.

We take claims of defects (incorrect weight, concentration, or quality) seriously. For incorrect weight claims, please provide your scale's make and model. For incorrect concentration or quality claims, please be prepared to send a return sample for analysis. Once verified, we will ship a replacement.

Most peptides should be stored in a cool, dry place, away from direct sunlight. Lyophilized (freeze-dried) peptides are typically more stable and have a longer shelf life. Reconstituted peptides should be stored according to the manufacturer's instructions, usually in a refrigerator or freezer. Always consult the product information for specific storage guidelines.

No, the peptides supplied by Power Peptides are strictly for research purposes only and are not intended for human consumption, diagnostic, therapeutic, or other personal uses. It is crucial to comply with local laws and regulations regarding the use of research chemicals.

Our single molecule product purity standard is ≥98% by HPLC and many of our products test ≥99%. Some products are standardized to a specific purity or have a more nuanced definition involving multiple active components.

Impurities are usually residual reagents, byproducts or side products. Some impurities can be toxic, so we aim for ≥99% purity whenever possible. If this is not possible at production scale, we carry the next best option (e.g. ≥98%, ≥95%) and make this publicly known on our COAs.

Peptide purity refers to the measurement of amino acids that made it into the proper chain to form the peptide. The remaining percentage are off-target peptide fragments. Peptides also contain water (moisture), counterions (salts) for stability and solubility, in addition to the active peptide chain.

Chromatographic purity depends on extinction coefficients and wavelengths used, so it approximates but is not equivalent to mass purity. HPLC reports have acceptable measurement error, so a ≥98% pure sample could report as ≥100% pure.

Our peptides are in lyophilized powder form. They are contained in glass crimp top vials with flip off caps but we can deliver in any container you request. Simply place a custom order.

When we decide to carry a product, we search for suppliers, request samples from the most reputable, and if samples pass verification, we make a larger order. We quarantine raw materials and evaluate them organoleptically. If they appear unadulterated, we send a sample to an accredited third party lab for analysis.

Our raw materials are synthesized primarily by manufacturers in China, with some in Europe and America, for economic reasons. This is not a concern as long as your vendor is conducting third party analysis. Our non-API materials are sourced domestically.

Our products are made in an ISO:9001 compliant facility. While manufacturing processes and equipment are proprietary, we discuss our QC processes on our Quality Control page.

We try to keep up with restrictions but recommend you seek qualified legal counsel. For US state restrictions, you will receive an error dialogue on checkout if your product is restricted in your jurisdiction.

That depends on your intended use. Our products are not approved for medical use, treatment, prevention, diagnosis, or cure of any disease or illness. They are unsuited for human consumption, and not approved for sale to or possession by anyone other than someone qualified to handle them in a laboratory setting.

Unless stated otherwise, we recommend a shelf life of 3 years from manufacture date with proper storage and handling, based on accelerated aging studies. Shelf life is variable and can be extended by deep freeze (-20°C or -80°C).

We provide storage instructions on product listings and labels. Generally, store in a cool, dry place away from heat, moisture and sunlight. Peptides should be refrigerated or frozen.

Use our website's search feature in the main navbar menu to determine if we sell a product. Look for the magnifying glass icon.

If the bottle didn't crack, it's OK, it just needs to warm to room temperature. Some products can precipitate out of solution at low temperature. If that happens, run the bottle under warm water and shake vigorously before use to re-suspend and re-solve.

This can happen from temporary low temperature exposure or if a nonpolar solution was undisturbed for an extended time. Remedy by running the bottle under warm water (50-70°C) for 5-10 minutes then shaking vigorously to re-suspend and re-solve. If that doesn't help, please contact us.

The molecules in our products are always degrading slowly. Changing storage temperature affects degradation rate. Lower than recommended temperature won't increase degradation, but may cause solutions to precipitate. Higher temperatures accelerate degradation. Less than 24 hours of human-tolerable temperatures will not substantially degrade products.

Our dedicated customer support team is here to help. If you have any questions or concerns not covered in the FAQs, please don't hesitate to contact us at [email protected] or via WhatsApp at +1 (646) 630-7291. We value your feedback and respond to all inquiries promptly, usually within 4 hours.
