3D Secure, also known as Verified by Visa, MasterCard SecureCode or Amex Safekey, is a method of authentication security, which was developed by the Card Schemes to enhance the security of online transactions for all cardholders. It allows only the cardholder to use the card when shopping online.

The three domains referred to in “3D” Secure consist of the cardholder to issuer domain, the merchant to acquiring bank domain and the interbank domain. Very simply, the system authenticates the cardholder before any transaction can take place, by diverting the cardholder to the browser of the bank that issued the card.

The bank then requests a password or One Time Password/PIN (OTP), from the cardholder, which is typically sent to their mobile phones, which will prove that the person undertaking the online transaction is the authenticated cardholder and therefore entitled to use the card.

Peptides vary in the degree to which they are soluble in bacteriostatic water. This is especially true of ones which contain multiple hydrophobic amino acid residues. If you have difficulties in dissolving the peptide, we recommend you use a small quantity of dilute (approximately 10%) of aqueous acetic acid for basic peptides or aqueous ammonia for acidic peptides. The addition of these liquids should improve the dissolution of the peptide.

During the lyophilization process, a nitrogen flush is added to remove any contaminants. This stage of the manufacturing process can affect the appearance of the peptide. Other factors such as the temperature or the leakage of water vapour from the vial can cause the contents to stick to the side of the vial. Although it may not be visible to the human eye, all our vials are filled automatically and contain exactly the same quantity of peptide.

No. The only products we sell are those you can see on our website. These products are peptides for research purposes.

Our products are sold on the understanding that they are exclusively for research purposes only. They should never be used for the treatment of any medical condition, deficiency or disease or be added to food for human consumption.

Peptides come in a variety of shapes and sizes due to their nature. Often the ‘cake’ may break during transit. This is normal and doesn’t affect their quality or potency. Also, proteins like LR3 are naturally larger than GRF or GHRP.

Yes, absolutely. We stand by the quality of all our products and strongly urge you to have them tested by any impartial third party laboratory. Tests which can be carried out include mass-spec, AAA, Maldimass and HPLC.

It is the customer’s responsibility to ensure they know which peptide is the most appropriate for their research purposes. For obvious reasons, we could never resell a product which had been returned to us. We can only replace if it is clear that it has suffered damage in transit.

We send all orders with only your name and address on the package. The order itself is wrapped in bubble wrap to ensure it won’t be damaged in transit. In this way, we ensure full security and complete discretion. We are considering your privacy at all times so parcels are sent with no indication of their contents inside along with a return address.

Please complete this payment information page on our website once you have made your bank through your Bank.

Peptides must be mixed with bacteriostatic water and/or acetic acid. These liquids keep the peptides fresh, prevent them from deteriorating and keep them free of bacteria for longer periods. Before using bacteriostatic water which has been kept in the fridge, allow it to reach room temperature as this will facilitate dissolution. In general, simple peptides will only require the addition of bacteriostatic water. However, more complex and long chain peptides will need a small quantity of acetic acid (10-20%) which is then topped up with bacteriostatic water.

Peptides should be stored in a place away from direct heat and sunlight.

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.

Even though we do not use any of your banking information on the site, your data is still secure because our site is browsed through the https protocol.

We keep our prices low because we manufacture and supply directly to you

Yes. After we receive your order by email, we create your invoice an email it to you.

As part of our discretionary measures with regards to customs clearance, country dependant, we sometimes have to ship vials unlabled. Color chart for peptide lid lid colors received can be requested by email or on Whatsapp.

Our delivery will take under normal circumstances, 6 and 8 days depending on what Country you are located in. With on and off Covid related border closures delivery can take up to 14 days.
