We verify every batch of every product with the help of accredited independent third party laboratories. The equipment and methods required for each product vary widely. For this reason we work with several specialty labs and PhDs in analytical and organic chemistry to design our analytical methods Analytical techniques we use include NMR, FTIR, HPLC, LC-MS, GC-MS, TLC, ICP-MS, Gravimetry, UV-Vis, Titration, Melting Point, Organoleptics.

Third party testing helps assure you are getting exactly what you paid for. A vendor can tell you whatever they want but if an independent third party registered lab is certifying it, what they say will carry more weight.

Let’s go into detail about what that means. A third party lab is a lab that is not run by the vendor or the manufacturer (first and second parties). The third party lab should also be independent, meaning they are not controlled by the other parties and have no conflict of interest about the results of analysis.

It’s important the lab is reputable. If the lab doesn’t know what they’re doing or cuts corners it means their analysis might not be valid. There is a lot of fraud in the analytical chemistry industry, and it’s important to work with companies that value integrity and ethics. We’ve seen unethical labs ask their clients what they want the results to say, before they even get a sample in.

We work hard to assure our contract labs are both ethical and use well validated analytical methods.

All of our single molecule product purity standard is ≥99% and additive-free.

Yes we do. All product listing include a bulk pricing table. If you need additional price breaks or unlisted products please contact us and we’ll see what we can do for you.

We do not carry any solvents for reconstitution of peptides and we have no intention of carrying them in the future.

Unless stated otherwise we guarantee a shelf life of 2 years from the date of manufacture with proper storage and handling.

For a more detailed answer, let’s take altitude. Due to the second law of thermodynamics entropy is always increasing. As a result the active chemical molecules of a product are always degrading, albeit slowly. Eventually there will be a measurable decrease in potency. This can take several years with proper handling and storage.

Unfortunately we can’t provide a more precise answer. True shelf life is variable and in most cases little data is available for novel compounds. Shelf life decreases with exposure to heat, moisture, oxygen and sunlight, which can create free radicals and break chemical bonds. Shelf life can be extended by deep freeze (-20°C or -80°C). A powder ingredient in deep freeze could have a shelf life in excess of 10 years with minimal degradation. It is not recommended to store a liquid, oil or solution product at anything below room temperature because this will alter the solubility properties and may precipitate the mixture, rendering it non-uniform and difficult to measure without resuspension.

Every molecule has its own unique decomposition process. But let’s zoom out for a moment to provide a general understanding. Due to the second law of thermodynamics entropy is always increasing. On a long enough timescale most molecules are thermodynamically unstable. The molecules in our products are always degrading, albeit slowly. Eventually there will be a measurable decrease in potency. This can take several years with proper handling and storage. Changing the temperature of storage will affect the rate of degradation.

Let’s go over common scenarios.

1. If a product is exposed to lower than recommended temperature there will be no increase in rate of degradation, with the exception that a solution product may precipitate and thus lose uniformity.
2. If a product is exposed to higher than recommended temperature the rate of degradation will be accelerated. For illustration let’s say a product requiring room temperature storage is exposed to 115°F, in that case there may be an increase in the rate of decomposition but this may not be measurable without months of continued exposure. Meaning you could leave a product in heat for a few days and if after it is properly stored the shelf life will still be years.
3. If a product requires cold temperature storage, such as a deep freezer at –20°C, then the risk of degradation from high temperature exposure depends on the degree and duration and the presence of oxygen, moisture and sunlight. Oxygen, moisture and sunlight all produce free radicals and break chemical bonds that can accelerate degradation. Even so, less than 24 hours of human-tolerable temperatures will not substantially degrade any of the products we carry.
