Frequently Asked Questions

Orders and Shipping FAQs

We send our orders from the UK and the USA. In this way, we can guarantee speedy delivery and without hold-ups at customs.

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 indications of their contents inside along with a return address.

Standard delivery will take 7-20 days depending on what Country you are located and the delivery service you have selected.

This delivery option has full tracking with our logistic partners and is a reliable delivery option if you are in a hurry for your order.

We send off orders as soon as payment is confirmed but usually within 24-48 hours of your order reaching us or the same day if we receive your order by 4pm. Orders placed at the weekends won’t be sent until the following Monday.

Yes, we welcome customers from outside the UK. Bank Transfers can take 1-2 days before they reach our account so there might be a slightly longer delay before payment is confirmed. Orders are then processed and shipped as quickly as our UK orders. However, we can’t guarantee the same speed of delivery as it depends on the overseas postal service over which we have no control. Orders can arrive anywhere between 5 and 25 days.

Before ordering, you should make sure you have a full understanding of the laws where you reside. It is highly unlikely that your order will be seized by customs officers. However, if it were to occur, we would work with you to find a mutually acceptable solution.

With Shipping Protection, Direct Peptides guarantee delivery of your order it’s a simple as that. If your order is not received within 21 days from dispatch* we will resend your order. In the very unlikely event that your resent order is not received we will refund you. Australian orders are excluded from refunds but will receive TWO free resends to an address of your choice.

*21 days for Premium Shipping, 28 days for Tracked Shipping, and 35 days for Australian orders.

Payment FAQs

We offer 20% discount for new customers placing their first order.

Use code: 1storder at the checkout.

We keep our prices low because we work directly with manufacturers.

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.

Peptide FAQs

A peptide is a group of two or more amino acids attached by a peptide bond [1]. Amino acids are known as the building blocks of protein and play a crucial role in many of your body’s natural functions including stimulating hormonal activity or repairing damage to the body. Although they are produced naturally by our bodies, they can also be derived from animal or plant sources or be manufactured synthetically.

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

All of our peptides are sold in various sizes of vials of lyophilized powder, nasal spray or pre mixed cartridges.

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 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.

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.

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.

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.

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.

No. The only products we sell are those you can see on our website. These products are peptides for research purposes. Please don’t ask for anything else.
