UK Customers

Your parcels will still be sent out within 24 hours of ordering or same day if before 4pm Monday to Friday. Saturday orders will now be shipped Mondays.

We offer next working day guaranteed delivery before 1pm for a small contribution of £3.50. Please note that this is next working day.

International Customers
 
We will still send out all orders within 24 hours of ordering or same day if received by 4pm UK Time by International Signed For 1st Class Airmail. We cannot tell you the date on which you will receive it. Once it has left the UK and with the overseas postal services, we have no control and can take anywhere between 5 days and 28 days.

This is why we supply the tracking information to all customers, so that they can monitor the progress of their parcels. This is up to the purchaser to monitor, we cannot possibly do this for you.

All parcels require a signature upon receipt. If this is a problem for you then you can opt for Tracked only when international. You will need to notify us of this in the notes section of your order form or in an email before we ship.

If you wish to use this option then you must assume responsibility for delivery. By requiring a signature it allows for optimum security and no misunderstandings. 

All orders are dispatched from within the U.K. This allows fast delivery inside the U.K and Europe without customs issues.

We don't confirm payments as we get too many every day, along with numerous emails to answer. When your payment appears into our account, we ship the same day, then we send the customer confirmation and tracking. Please note international transfers can take several days.

Do not worry about your peptides and the storage of those peptides during transit to the destination. Even if this takes several weeks due to hold ups with customs etc. It is more important that they are in kept out of direct light.

We had all our peptides seized in march 2013 due to possible legalities. The authorities returned them back in the January of 2014 and obviously we were concerned that they may be damaged or no longer active. Therefore we had to send a sample of each peptide back to the USA for testing. We were pleased to receive confirmation that every one of the peptides was still active and no degrading of the peptides had occurred. They had only been kept in a closed dark room with no refrigeration.

Each aliquot of peptide is deposited into each vial via 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 vapor can escape the vial where it goes from a solid to a gas without every 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 solubilise 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 water of hydration

When peptides are received, ensure they are kept in a cool, dark place. For best preservation, store them under refrigeration at 4°C or colder, away from bright light. Dry peptides are stable at room temperature for weeks to months, but for long term storage up to 4 years, -20°C is preferred. Do not freeze/defrost and re-freeze.

No peptides arrive already reconstituted. You should not purchase any peptide that has been mixed/reconstituted as once they have been mixed you should keep them refrigerated at all times.

Peptides all need to be reconstituted / mixed with either Bacteriostatic Water / Acetic Acid or both.

Generally on the more complex and long chain peptides it is advisable to add a small amount of Acetic Acid (10 - 20%) first then top up to the desired level with Bacteriostatic Water.

Most simple peptides are fine to reconstitute with only Bacteriostatic Water. If you are keeping your Bacteriostatic Water in the fridge then allow to acclimatise nearer to room temperature before reconstituting with your peptide for better mixing.

These specialised waters keep the peptide from degrading, keeping the peptide fresh and bacteria free for longer periods. 

"Peptides can have widely varying solubility properties, depending largely on their primary sequence. While many peptides dissolve easily in bacteriostatic water (Containing 0.9% (9 mg/mL) of benzyl alcohol), some, especially those containing multiple hydrophobic amino acid residues, may not readily dissolve.

As a general procedure, we recommend first attempting to reconstitute peptides in bacteriostatic water. If solubility is still a problem, addition of a small amount of dilute (approximately 10%) aqueous acetic acid (for basic peptides) or aqueous ammonia (for acidic peptides) may facilitate dissolution of the peptide"

In the unlikely event that the order is seized we would work with you and offer you a solution. However, it is the responsibility of the purchaser to understand their local legislations.

The customer must understand before ordering Peptides, which peptides they require this is not our responsibility.

If a customer receives a parcel that looks like it may have been damaged during transit we will reship or refund the amount for the goods paid.

Please see FAQ " How long will it take to receive my parcel. " For any concerns regarding delivery timescale we cannot refund or reship until these procedures have been followed.

Please note we also have express courier services available at an additional cost.

Please contact us if you have any concerns .

We could not possibly resell returned vials of peptides to other customers and institutions for these obvious reasons.

A Peptide is any group of organic compounds comprising two or more amino acids which react by forming a link or peptide bond. Amino acids, the building blocks of protein, are reduced to protein fragments or peptides and communicate or interact with target molecules in your body to prompt or start an activity your body has slowed or stop performing.

In the past, the molecular size of amino acids could not easily pass through your skin rendering the product ineffective; altering the amino acid to a peptide fragment solved the issue. Specific active peptides target and regulate cell function, maximize collagen production by stimulating the growth of collagen cells resulting in the reduction of fine lines, increasing skin firmness and tone. Previously, researchers formulated skin care products

to replace low levels or deficient components of the skin, now peptides can intervene during the aging process signalling the skin to repair itself.

Proteomics, the study of proteins emerged from the human genome research unlocking the encoded genetic information of amino acids and the body. The sequence of these amino acids in the protein peptide determines the shape, properties and biological role of the peptide, some examples are stimulating hormonal activity or body repair.

Peptides can be synthetically produced, derived from plant and animal sources or made by the body. Current medical data is starting to connect peptide deficiency to eczema and the red itchy skin of dermatitis. Penta-peptide is five amino acids joined by a bond, "penta" is the Greek word for five. Poly-peptide is protein or part of a protein forming a chain of amino acids joined by a peptide bond, "poly" is the Greek word for many
