FAQ
1. What payment methods do you accept?
We accept payment methods such as PayPal and credit cards.
2. How can I track my order’s progress?
When you place an order, you receive a confirmation email with payment instructions and your order number. When your payment reaches our account, you receive a payment confirmation email. We will ship the same working day if we receive the payment before 1:00 pm CEST ( Monday – Friday ). Once we dispatch your order, you will receive an email with your tracking details. Please use these details to keep track of your parcel; it is not our job to follow each parcel we dispatch. Some international payments can take up to 3 days for the payment to show in our account.
3. Can I modify or cancel my order?
Yes, please send an e-mail to info@particlepeptides.com if you wish to modify or cancel your order. Your order can only be modified or canceled if it hasn’t been shipped yet. Our customer support team will assist you in modifying or canceling your order and issuing a refund where necessary.
4. Don't peptides need to be kept at a certain temperature during transit?
The temperature of the peptides during transit is not of concern. For them to remain active, the most important factor is that they are kept out of direct sunlight. Peptides will arrive in lyophilised powder form. Short-term temperature change during shipping should not affect the product quality and efficacy.
5. How should I store my peptide when I receive it?
Peptides should be stored in a cool place away from direct heat and sunlight. For long-term storage we recommend to store lyophilised peptides in freezer at temperature –20 °C. Most peptides can be stable at this temperature for years without significant degradation. The shelf-life of reconstituted peptides is limited. We recommend to store the reconstituted peptides at temperature 2-8 °C. Most peptides in solution can be stable at this temperature for 3-12 weeks.
6. How can I reconstitute my peptides?
Peptides must be mixed with Sodium chloride 0,9% solution, Sterile water, Bacteriostatic water and/or Acetic acid, depending on particular peptide. Before using solvent which has been kept in the fridge, allow it to reach room temperature as this will facilitate dissolution. Lyophilised peptides should be also allowed to warm to room temperature before the reconstitution.
7. Why do peptides differ in appearance?
Each aliquot of a peptide is deposited into each vial via a machine. The vial is then stoppered and moved inside the lyophilizer. Once in the lyophilizer, the vial is then given a nitrogen flush to rid any contaminates. This is the phase that will determine the appearance of the contents. Sometimes the water vapour can escape the vial where it goes from a solid to a gas without ever going through a liquid phase. This will make the contents adhere to the sides of the vial leaving very little to see by the naked eye. Other times, depending on several other factors including temperature, the appearance can look like a solid puck, a few smaller pucks, a powder material, or even just a few specks, but the amount of actual material is the same. When freeze-drying products without any matrix (sucrose or mannitol for example) sometimes the residual water of hydration will cause a collapse via hydration of product before it fully dries. In other words, when the water from the ice crystals is removed what remains prior to secondary drying (when the chamber is warmed) can combine and solubilize the remaining material causing it to collapse. Sometimes it forms crystals and sometimes it forms films dependent upon how much there is local melting and what the temperature and vacuum levels are at the time of the collapse. Very complicated but it tends to happen far less when sucrose, for example, is around since the sugar hydrogen bonds to the protein/peptide like the water did and thus less water remains bound as the water of hydration.
8. Where are the orders sent from?
The order was shipped from China
9. How long does it take for my order to be delivered?
The estimated time of arrival for orders shipped depending on what Country you are located and the delivery service you have selected. EU orders are usually delivered in 2-7 business days. International delivery times vary greatly between 7-21 business days depending on the destination. Please note that once your order has shipped from our facility, we have no control over any type of delays, so we are unable to guarantee the exact time of arrival. Our customer support team is available via email if you have any questions or concerns regarding your delivery.
