Peptide warehouse offers a range of different products that are synthesized in their own certified laboratory. They have both research and cosmetic peptides for sale. They have a good selection of products with customer ratings and brief descriptions of the product. Their website also provides a lot of information on the different kinds of peptides and their benefits.
Their website is well designed and has a simple layout that is easy to navigate. There are informative pictures of the peptides and very little extra clutter. They also have a number you can text to get quick responses from a sales associate. This is a great feature for those who are hesitant to purchase online.
The peptides are shipped in lyophilised powder form, which means they will be stable at room temperature for weeks after delivery. However, they should be stored in a freezer at -20 degC. Repeated freezing and thawing may cause degradation of some peptides.
This company claims to be an ISO 9001:2008 certified company. But, they don’t actually seem to be. In fact, their ISO certification expired back in 2018. Unless they’re using it as a smokescreen to cover up their poor quality, I wouldn’t trust them.
I would recommend looking elsewhere for your peptides. They have a lot of negative reviews on the web and a history of dissatisfied customers. There are a lot of other companies out there that offer similar peptides at better prices with more testing and more transparency.
