You are not the only one! Extreme Peptides has a strong reputation in the peptide industry for the consistency of our purity levels.
Purity is a big factor when buying American Ghrp 6, but how do you know that we aren’t just like the other guys claiming to sell USA made peptides? What is purity? How is purity measured?
Peptide Purity
There can be significant variations in the composition of peptides. So how do you know if a peptide is ‘pure’ or not? Purity can have many meanings, but in this setting we are talking about chemical purity, defined as the degree to which a substance is undiluted or unmixed with extraneous material. This measurement is typically expressed as a percentage. For example, if the percentage is 100%, no other chemicals or compounds are present. If the percentage is 50%, about half of the peptide’s composition is diluted with other substances.
As the world’s most popular purveyor of research peptides and chemicals, purity is a big deal to Extreme Peptide. We hope to portray our commitment to peptide purity with this brief explanation on how to digest our quality control tests.
Independent Testing
The HPLC and Mass Spec explained:
(HPLC test)
This is a chemical test known as an HPLC, which stands for high performance liquid chromatography.
HPLC is a technique used to separate the components in a mixture. In short, it’s a test that will tell you if the mixture has any contaminates. Simply stated, we refer to it as the “Pure / Not Pure” test. An HPLC test should only have 1 “spike” on its graph. This indicates that the only compound present in the compound is the compound we tested in the Mass Spec test. Additional “spikes” shown by the HPLC indicate contaminates or other unwanted compounds present. For a more detailed description click the link provided.

(Mass Spec test)
This is a chemical test known as the Mass Spectrometry (commonly referred to as a Mass Spec). Mass Spec is a technique used to determine the elemental or isotopic structure of a sample. We call it the “Is it what its supposed to be” test. With Mass Spec we can tell if a given sample has the molecular signature it is supposed to have. The “spike” or “spikes” shown on a Mass Spec indicate the purity level of the compound being tested. With the Mass Spec test you want to see one “spike” within the 95%-100% range. This indicates that the compound has no other properties and that it is a pure form of the compound being tested. If two or more “spikes” are shown the compound has been contaminated.
