Frequently Asked Questions
Yes. All of our peptides come in a raw lyophilized (freeze-dried) powder form and must be reconstituted with bacteriostatic water, which must be purchased separately elsewhere online, as we do not carry it.
Good question. Our primary leverage is volume and industry experience. When we purchase material at large scale we benefit from economies of scale in manufacturing and quality control. Combined with best practices and well developed processes we are able to price competitively while spending more on quality control.
Our prices are derived from operational costs plus a minimum margin that allows us to reinvest in the development of new products. We believe in sustainable business practices, so that we can focus on your needs, your satisfaction and the development of products that create the most value for clients.
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.
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.
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.
Our products are not approved for medical use or for the treatment, prevention, diagnosis, or cure of any disease or illness. In addition to being unsuited and unsafe for human consumption, they are not approved for sale to, or possession by, anyone other than someone qualified to handle them in a laboratory setting. We encourage our clients to seek qualified legal counsel in reviewing their potential use of our products, but we cannot provide such counsel ourselves.
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.
To preserve the integrity of laboratory results, proper storage of peptides is essential. Correct storage practices can maintain peptides for years and guard against contamination, oxidation, and degradation that may render your peptides, and therefore experiments, useless. While some peptides are more susceptible to degradation than others, knowing and implementing the best practices for peptide storage can greatly lengthen their stability and integrity regardless of composition.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
Additionally, it is important to avoid repeated freeze-thaw cycles. This can increase the peptide’s susceptibility to degradation. Also, frost-free freezers should be avoided to store peptides, as temperatures can fluctuate widely during defrosting cycles.
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.
- 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.
- 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.
- 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.
Currently we accept Zelle, Credit & Debit cards & Crypto payment options at checkout.
All orders ship via USPS First Class or Priority Mail and most orders will ship in 2-3 business days.
If you have an order with backordered items on it, what we have it stock will ship as soon as possible, and the rest will ship as soon as it is ready, typically 7-10 business days.
No, we only ship within the United States. If an order is placed with an address outside the U.S. it will be canceled immediately.
All items are shipped securely and in a manner that ensures safe arrival. If this is not the case please contact us immediately with photographic evidence. Once adequately verified we will ship a replacement.
No they are not the same. While they can both be used for reconstitution, we recommend bacteriostatic water as it has a longer shelf life and is more widely available online.
All of our peptide vials are 3mL in volume.
