Storage

 Peptides are increasingly gaining traction in various research fields. To achieve the best outcomes, it’s crucial to understand the ins and outs of peptide storage and reconstitution. This comprehensive guide will walk you through essential tips for maintaining peptides' highest quality and effectiveness.

Peptide Storage: Preserving Quality and Stability

 Proper storage is vital for maintaining the stability and potency of peptides. Peptides in their lyophilised (freeze-dried) form are safe for transport as they are protected from UV light and remain stable in a freeze-dried state. However, we recommend refrigerating them as soon as possible upon arrival to ensure proper storage and extend their longevity.

At JOPEAR , we take storage seriously. We maintain peptides in a controlled environment with a temperature-controlled walk-in freezer and three medical fridges, all closely monitored for optimal temperature stability. Peptides stored at -20°C in a freezer will remain stable for up to 48 months, making this ideal for long-term storage. When you receive peptides, it’s best to store them immediately in your refrigerator (2-8°C) or freezer (-20°C) for extended preservation. For added protection, you can also purchase one of our storage cases.

Note: Peptides degrade gradually over time, and degradation doesn’t mean reduced potency initially. However, as peptides break down, they can lose their structure and charge, leading to fragmentation and eventual loss of effectiveness.

About US

The story of JOPEAR BIO is inspired by the tea-growing regions along China’s eastern coast areas known for their rich botanical resources and refined craftsmanship.
For generations, our family has been engaged in tea cultivation and trade,
developing a deep understanding of plant ingredients and extraction techniques.
With a passion for nature and expertise in precise cultivation,
we started as a small tea planting and grinding workshop.
Building on our tea heritage, we began developing tea polyphenol extraction technology in 2015.
Over the past decade, we have grown from a single product line into a diverse range of botanical extracts,
accumulating valuable industry experience and partnerships along the way.

In 2022, Tingting , the founder of JOPEAR BIO, arrived in the United Kingdom and was deeply inspired by the natural beauty. The landscape, climate, and biodiversity of the UK sparked her vision to connect Eastern botanical resources with Western scientific innovation,and to provide reliable, high-quality raw materials to clients in the UK and worldwide.

In the summer of 2025, JOPEAR BIO was officially established in London,
serving as a distribution and collaboration platform that bridges China’s biotechnology expertise with the international market.

Although JOPEAR BIO is a newly established company,
our team has many years of practical experience in the distribution of botanical extract ingredients and peptides.
In the UK, we are not a manufacturer, but we understand that every batch of raw materials is a gift from the Earth.
We maintain long-term partnerships with reputable collaborators
to ensure transparency of sourcing and full traceability throughout the process.
By optimizing warehousing and transportation management,
we reduce energy consumption and carbon emissions.
We value building stable and trustworthy relationships with our clients,
comply with UK and international trade standards,
and continuously refine our operations
to provide efficient, professional, and reliable service,delivering high-quality products and prompt support to our global partners.
