Frequently Asked Questions
What are your products for?
Laboratory research only. Every item we sell is intended strictly for 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.
What if a product I want is out of stock?
Email us or use the contact form and ask about that item. We will tell you where it stands and when we expect it back. We do not take preorders or backorders, so the listing is always the live answer.
How much heat or cold can it take before reconstitution?
Before reconstitution the material is a sealed lyophilised powder, and it handles temperature far better in that form than it does in solution. Keep it cold, dry, sealed and out of direct light. We do not publish one temperature range for the whole catalog, because it varies by product. The range for the item you hold is stated on its certificate of analysis (COA), and we will confirm it against the supplier's documentation if you ask.
What is the shelf life?
Shelf life is set per product and per batch, so there is no single figure for the catalog. The figure for the vial you receive is recorded on its COA, and we will confirm it against the supplier's documentation before you order. Any stated shelf life assumes the material has been kept sealed, dry and cold since it was filled.
What temperature and humidity does it need after reconstitution?
Once the material is in solution it is far less forgiving than the dry powder. Keep it refrigerated, sealed and out of light, and keep moisture off the stopper and the vial mouth. The temperature and humidity range for a reconstituted product comes from its COA and the supplier's documentation, not from us. Ask and we will confirm both for the item you hold.
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: $15.00. That is the only shipping charge, no matter the size of your order.
Do you run sales or discounts?

How do I contact support?

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.
