Research peptides: what they are and how they are handled

A research peptide is a short chain of amino acids synthesized in a laboratory and intended exclusively for scientific research (RUO). It is not a medicine or a supplement: it is distributed lyophilized, reconstituted with bacteriostatic water and handled as a laboratory reagent. At NeoPeptidos every compound is delivered with ≥99% HPLC purity and a batch COA.

What is un péptido de investigación?

A peptide is a short chain of amino acids joined by peptide bonds, smaller than a protein (generally 2 to 50 amino acids). In research they act as biological signals that modulate specific receptors and cellular pathways. Research peptides are produced for laboratory use only (research-use only) and are not approved for human use.

How does a peptide differ from a protein?

The difference is size and folding: peptides have a few dozen amino acids, while proteins are much longer, folded chains. Because of their size, peptides usually act as messengers or modulators that bind to receptors to trigger a cellular response.

What types of research peptides are there?

They are grouped by their area of study:

How are they handled in research?

Peptides are distributed lyophilized (as powder) and reconstituted with bacteriostatic water before use in the laboratory. Unreconstituted vials are stored at -20 °C; once reconstituted they are kept refrigerated between 2 and 8 °C. All handling is for research use only (RUO).

RUO notice: NeoPeptidos products are research-grade material. They are not medicines or supplements, they are not approved by COFEPRIS or any other agency for human or veterinary use, and they are intended exclusively for scientific research.

How is quality verified?

The standard in the serious industry combines three controls: purity by high-performance liquid chromatography (HPLC), identity confirmation by mass spectrometry and a batch Certificate of Analysis (COA) issued by an independent laboratory. Every NeoPeptidos batch reports ≥99% purity and its corresponding COA.

Frequently asked questions

What is un péptido?▾
A short chain of amino acids (generally 2 to 50) joined by peptide bonds, smaller than a protein, that acts as a modulating biological signal.
Is a peptide the same as a protein?▾
No. It is a difference in size: peptides are short chains; proteins are much longer and folded.
What are peptides studied for?▾
They are investigated in metabolic, regenerative, cognitive, longevity and hormonal areas. They are distributed as reagents for research (RUO).
Are research peptides approved for human consumption?▾
No. They are research-grade material for laboratory use only; they are not approved by COFEPRIS or intended for human or animal consumption.
How are they reconstituted?▾
With bacteriostatic water (included at no cost in every order). The exact volume depends on the peptide's weight; you can calculate it with the site's reconstitution calculator.
