Don't take our word for it
Every vial has a paper trail.
Match the lot number on your label to its certificate in seconds.
Beyond purity
A purity number is only the start
HPLC tells you how much of the vial is the target peptide. It can't see these four things, so we test for them separately.
01
Endotoxin
Cell-wall debris left by bacteria during manufacture.
- What HPLC misses
- HPLC reads molecular purity. Endotoxin is biological, so a vial can pass HPLC and still carry it.
- Why it matters
- Even trace endotoxin provokes an inflammatory response in cell and tissue models, which skews results before an experiment starts.
02
Sterility
Whether anything is alive in the vial.
- What HPLC misses
- A clean chromatogram says nothing about bacteria, yeast or mould. That takes a culture test.
- Why it matters
- Microbial growth adds an uncontrolled variable to every assay the vial touches.
03
Heavy metals
Lead, arsenic, cadmium and mercury carried over from reagents.
- What HPLC misses
- Metals are inorganic and invisible to HPLC and mass spec. They need a separate ICP-MS run.
- Why it matters
- Metals interfere with enzymes and accumulate over long studies, confounding the data.
04
Lot consistency
Whether this lot behaves like the last one.
- What HPLC misses
- One vial per run is the usual spot-check. It cannot show drift between lots.
- Why it matters
- If the material drifts between orders, so do your results. Reproducibility depends on it.

FAQ
Questions, answered
Who can buy from Thesis Scientific?
Our products are sold only to qualified researchers aged 21 or over, for laboratory research. They are not for human or veterinary use, and we do not provide usage or dosing guidance.
How does Buy 2, Get 1 Free work?
Add any three eligible vials — they can be different products — and the lowest-priced one is free. Six vials get the two lowest-priced free, and so on. The discount is applied automatically at checkout. Research stacks are already priced below it, so they are not counted again; supplies are not included.
Where do I find the COA for my vial?
Every product page links to its certificates, and the COA library lists them all. Each certificate carries a lot number that matches the label on your vial.
How fast do orders ship?
In-stock orders placed before the daily cutoff are dispatched the same business day. Shipping options and delivery estimates are shown at checkout, and orders over $150 ship free.
How should vials be stored?
Keep lyophilized vials frozen or refrigerated, away from light and moisture. Storage details for each compound are on its product page and certificate.
Can I return an order?
Because of their nature, research compounds cannot be returned once shipped. If an order arrives damaged or incorrect, contact us within 72 hours of delivery and we will make it right.
Do you offer wholesale or lab pricing?
Yes. Institutions and labs ordering in volume can apply for wholesale terms on the wholesale page.
