Question 1

How do I verify the purity of my vial?

Accepted Answer

The lot number is included in the packaging. Send it to us and we will share the certificate of analysis for that exact lot, including HPLC purity and mass spectrometry identity results.

Question 2

How should peptides be stored?

Accepted Answer

Lyophilized vials should be kept refrigerated at 2 to 8 C and protected from light. Unopened vials stored this way remain stable for the period printed on the certificate of analysis.

Question 3

How fast do orders ship?

Accepted Answer

Orders placed before 2 pm local time ship the same business day. Everything else ships within 24 hours. Orders go out with Estafeta for next-day delivery, in packaging that protects the vials from impact.

Question 4

Which peptides can be ordered together?

Accepted Answer

Any combination. Each product page lists the peptides most often paired with it, and our team can help you decide if you are unsure.

Question 5

What is your return policy?

Accepted Answer

To protect the integrity of every vial, we cannot accept returns of opened or shipped product. If an order arrives damaged or incorrect, contact us within 48 hours and we will replace it.

Question 6

How much is shipping?

Accepted Answer

Shipping is free on orders over $3,000 MXN. Orders below that ship next day with Estafeta for a flat $220 MXN, shown at checkout before payment.

Question 7

Who tests the peptides?

Accepted Answer

Every lot is tested by Janoshik Analytical, an independent third-party lab. For now the certificates come from our supplier, who submits each lot for testing, so the COA lists the supplier as the client rather than Vectra. It covers the same lot as your vial, matched by lot number. We plan to submit our own vials so future certificates carry the Vectra name.

Question 8

Where do you ship?

Accepted Answer

We ship within Mexico only. We do not ship internationally at this time.
