Have Questions? We Have Answers.
Everything you need to know before your first order.
How is the optimal temperature of the peptides maintained during delivery?
All our shipments are sent in special cooling boxes that maintain the required temperature during transportation. This ensures that the products reach you in perfect condition.
How should peptides be stored?
Once you receive the peptides, it is important to store them properly to maintain their stability and effectiveness. We recommend storing them at a temperature between 2°C and 8°C in a refrigerator. This ensures that the peptides retain their properties throughout their entire shelf life.
How long does delivery take?
Once you place your order, we process and ship it within 1–2 business days, with DHL Express to your specified personal address.
What should I do if the pen arrives slightly warm?
The formulas are stabilized using Molecular Structure Stabilization Technology (MSSPT) and can withstand short temperature fluctuations above 8°C. In such cases, there is no need for concern – the product’s quality and effectiveness remain fully preserved.
Can different peptides be combined?
Yes, most formulas are compatible and can be combined according to research objectives.
