Frequently Asked Questions
What are your products for?
Laboratory research only. Every item we sell is intended strictly for in-vitro research and development by qualified researchers. Nothing we sell is for human or animal consumption.
Are your peptides tested?
Yes. Every batch is third-party tested by an independent laboratory for identity and purity before it goes on sale.
Why is everything out of stock?
We list our full catalog so researchers can see exactly what we carry and at what price. Items show as out of stock until inventory is on the shelf and verified. No preorder games, no backorder surprises.
How fast do you ship?
In-stock orders ship within 24 hours, in plain discreet packaging.
What does shipping cost?
Flat fee shipping anywhere in the US: $10.00. That is the only shipping charge, no matter the size of your order.
Do you run sales or discounts?
No. No fake sales, no marketing games. Our everyday price is the lowest price we can offer, every day.
How do I contact support?
Email support@optimizedpeptidesolutions.com or use the contact form. Support hours are Monday to Friday, 9:00 AM to 5:00 PM EST.
What is your return policy?
See the full Refund and Returns policy. In short: because of the nature of research materials, we cannot accept returns of opened product, but we make damaged or incorrect orders right.
