One batch, one number, one certificate
Every vial that leaves here has its batch number printed on it. That number pulls up the certificate of analysis for that exact batch: which compound it is, what purity it came back at, and the method used to measure it. No generic results, no single PDF covering the whole catalog.
- Purity by HPLC
- Identity confirmed
- Cold chain in transit
- Order preparation
How every batch is verified
No vial ships without analysis. If you want the documentation before buying, ask and we send it over.
See how we testHPLC analysis
High-performance liquid chromatography determines the purity of the batch.
LC-MS confirmation
Mass spectrometry confirms the measured molecular weight matches the compound.
Sterility and endotoxins
Microbiological screening and chemical contaminant analysis before batch release.
COA with the order
The certificate ships with the order, with batch number and analysis date.

Request a quoteFrequently asked questions
What labs ask before their first order.
What can these compounds be used for?+
In vitro laboratory research and analytical chemistry only. They are not pharmaceutical grade and cannot be administered to humans or animals.
What purity are they?+
The specification across the catalog is ≥99%, determined by HPLC. The exact percentage of the batch you receive is on its certificate of analysis.
What does the certificate of analysis include?+
Compound identity confirmed by LC-MS, purity by HPLC, batch number and analysis date. It ships with the order and we send it before purchase on request.
How long does shipping take?+
Prepared within 24 to 48 business hours. Shipping is included in the price across Mexico with no minimum. We send tracking on WhatsApp when it ships.
How do the vials arrive?+
Lyophilized and sealed, in rigid packaging with a cold pack and double box. Each vial is labeled with compound, content and batch number.
How are they stored?+
The sealed lyophilized vial is stored at -20 °C protected from light. Once reconstituted with bacteriostatic water, refrigerate between 2 and 8 °C.
Do I need bacteriostatic water?+
Yes, to reconstitute any lyophilized vial. We sell it separately in a 10 ml format and it is also included in the collections.
What payment methods do you accept?+
SPEI bank transfer and cash on delivery. When you confirm the order we hand you the CLABE and the exact amount; the receipt releases it. We never ask for or store card data on this site.
Do you issue invoices?+
Yes. At checkout you tick that you need an invoice and leave your tax ID and billing email. The account you transfer to depends on whether you invoice, and we show it on the payment screen.
How do you keep the cold chain outside Tulum?+
Orders outside Tulum ship with FedEx Express under 2-8 °C temperature control, in rigid packaging with a cold pack. That service covers Cancún, Playa del Carmen and Tulum.
Do you accept returns?+
We do not accept returns of opened or reconstituted vials. If a vial arrives damaged, with a broken seal or incorrect, it is replaced at no cost when reported within 48 hours with photos.
Do you advise on dosing or protocols?+
No. We give no dosing or administration guidance. Technical support covers identity, format, handling, storage and batch documentation.
Is there volume pricing?+
Yes, for labs and institutions with recurring purchases or bulk orders. Quoted case by case with a specialist.
