Where we come from
We come from sport and science
We are a team of athletes and people who are into biology. We care about performance, physiology and what can be measured — and that is exactly what we could not find when we went to buy research peptides in Mexico.
What was on offer was taking someone's word for it. No analysis, no lot number, no way to verify anything the label said. You could pay, receive a vial and have no way of knowing what was in it.
Nexa Labs started to close that gap: so that buying a reference compound in Mexico would not depend on trusting a stranger, but on an analysis anyone can read.
Who we are
We import, store and ship from Mexico.
We are a Mexican research peptide company. We import, store and ship from here, so the material you order is already in the country the day you buy it.
That is what you save: paying in dollars, waiting weeks and not knowing where your package is. You pay in pesos and it arrives in days.
What you save
No dollars, no waiting
Prices in pesos and shipping inside Mexico. We already did the importing.
What defines us
How we work
- Rigour per lot
- Every size we publish has its own lot number and its own certificate of analysis — we do not recycle a generic COA across different products.
- Nothing hidden
- Price, real stock and available size all show on the same product card, with no small print and no "message us on WhatsApp" just to find out what it costs.
- Someone answers
- Behind the catalog there is a small team that replies directly — not a generic chatbot or an inbox that takes a week.
- Built from Mexico
- Prices in pesos, plain packaging and delivery times worked out for Mexico, not a translation of a store priced in dollars.
- Careful handling
- Sizes that need it are prepared and packed to preserve their integrity over the journey to your home or laboratory.
- Research only
- Every product is labelled and sold explicitly as Research Use Only. We neither promote nor enable human or animal use under any circumstance.
What we do not do
Just as important as what we do
We do not relabel
Every vial carries the lot number that belongs to it. When a lot runs out, the product stays sold out until the next one arrives with its own analysis.
We do not sell without paperwork
A product whose analysis is not finished is not published. If the document is not on the product page, that lot is not on sale yet.
We do not promise effects
On this site you will not find what a compound is for or how much to use. They are reference materials for research and that is how they are sold.
For research use only
All Nexa Labs products are reference compounds for scientific research (RUO), labeled Not for Human or Animal Use. They are not medicines, supplements or consumer products.
