Have Questions?
We Have Answers.

Here are some of the most frequently asked questions we receive. For more information, please visit our Video Q&A section for even more information about HalfwayGray.

What are research peptides and who are they for?

Research peptides are synthetic compounds intended strictly for laboratory research and development. They are not approved for human or veterinary use. All products sold by HalfwayGray are labeled for Research Use Only (RUO) and are intended for qualified professionals and institutions conducting in vitro studies, assay development, or related scientific applications.

Are your peptides made in the U.S.?

Our peptides are sourced directly from international manufacturers known for high-quality standards and sterile production environments. By acting as a direct bridge between researchers and these manufacturers, we eliminate the hassle of customs, import duties, and international delays—while offering significant cost savings.

Is HalfwayGray a licensed pharmacy or compounding facility?

No. HalfwayGray is not a pharmacy, medical provider, or compounding lab. We do not diagnose, treat, or advise on the use of any products. We simply supply RUO-labeled materials to qualified researchers for laboratory applications.

Do you ship to all U.S. states?

Yes, we currently ship to all 50 states. However, it is the buyer’s responsibility to ensure they are complying with local regulations regarding the purchase and use of research chemicals. HalfwayGray is not liable for misuse or unauthorized applications.

Do I need a prescription to buy from you?

No prescription is required. All products are sold as Research Use Only (RUO) compounds and are not intended for human consumption or therapeutic use. By purchasing, you confirm that you are a qualified individual or entity conducting legitimate research.

Can I return or exchange a peptide order?

Due to the sensitive nature of research compounds, all sales are final if the vials have any signs of being opened or used. We do not accept returns or exchanges once an order has been used. If your package arrives damaged or incorrect, please contact our support team within 3 days of delivery and we’ll make it right.

Why are your prices lower than other peptide sites?

We don't pretend to be a pharmaceutical brand or inflate prices with unnecessary middle layers. HalfwayGray acts as a direct conduit between overseas manufacturers and U.S. researchers, allowing us to offer high-purity peptides at a fraction of typical market prices.

Will I receive tracking information for my order?

Yes. Once your order is processed and shipped, you'll receive an email with tracking information. Most packages ship within 1–2 business days and are delivered via trusted U.S. carriers. Please allow 24 hours for tracking to update after receiving your confirmation.

What’s included in my order?

Each order includes the peptide vial(s) you've selected. No instructions or dosing information are provided, in accordance with our RUO-only policy.

Do you guarantee product quality?

Yes. While we cannot make medical claims, all of our peptides are tested for purity and sterility by the manufacturer and are stored and shipped in appropriate temperature-controlled conditions. If your order arrives damaged or compromised, we will promptly replace it. Sometimes the lypholized powder can cake, turn into a puck, or even appear 'broken'. These are all normal and do not affect purity or effectiveness of the peptide.

Can I get customer support if I have a question?

Absolutely. Our U.S.-based support team is available via email at hello@halfwaygray.com and typically responds within 24 hours during business days. While we can’t advise on use, we’re here to help with order questions, shipping issues, or general support.
