NOTICE: Laboratory Closed for Vacation

24th July 2021

The laboratory will be closed from the 30th July until the 9th of August. To minimize disruption to subscriptions: those subscriptions which would normally be sent on the 3rd of August will be sent on the 29th of July, and those orders due to be sent on the 5th of August will be sent on the 10th of August. We appreciate your patience while we are closed but please contact us at if this will cause any issues.

Notice: Small Price Increases Starting November 15, 2020

11th November 2020

We are again at the time of year when we must make a small increase in our prices. As always, we have absolutely tried to minimize the increase.  (For a new list of prices, starting November 15, 2020, please see the Buy Now page.) This has been an unprecedented year and the pandemic has meant that many of the materials we use in the laboratory, to produce HDC that are as clean and free from contamination as possible, have seen huge price increases.  We thank you for all your patience during this incredibly difficult time.

IMPORTANT NOTICE FOR JUNE 15, 2020 – Issue with Our Email!!!

15th June 2020

  1.  Email Judy at
  2. Call the lab at 01525 555 982
  3. Call Judy at 914 241 0673

Thank you for your patience and understanding.


Small Increase in Postage

14th June 2020

We have received notification from the UK’s Royal Mail that prices have gone up for UK shipping and for international tracked shipping.  We are forced then to raise those prices slightly to cover that difference.  International tracked shipping will now be £14.00.  UK shipping will now be £2.40.  Thank you for your understanding.

New COVID Shipping Policy

13th April 2020

We are aware that postal services worldwide are not as reliable as normal during this COVID19 pandemic and that delivery times have started to increase. We are also aware that there has probably not been a more important time for our clients to have regular access to HDC and we have been trying to develop methods that would allow longer shipping times. Unfortunately, we have not been able to significantly increase the amount of time the HDC live in the shipping fluid.

However, starting on the 9th April, we have started to add significantly more HDC to each vial we send out. We already know that the HDC die off gradually with time, which is why we have, until now, only allowed 11 days for shipping. However, by adding 30-40% more HDC to each vial, we can allow for the drop in live HDC expected after 11 days, and still ensure you have at least the number of HDC you order even if your vial takes 14 days to reach you. Those people who receive their vials within the normal 11 days will simply benefit from a few extra HDC.

To repeat:  starting from the 9th April we have been sending out up to 40% more HDC with each vial allowing up to 14 days shipping.  Refunds or replacement vials will only be given now after 14 days, until such time as the postal services go back to normal.

With regards to possible transmission of COVID19, the virus is thought to only survive up to 3 days at the most on surfaces, so in nearly all cases this is not an issue. However, while continuing to maintain the strict cleaning procedures we already use for production of the HDC, which would kill any bacterial or viral contamination, we are also taking further precaution buy sterilising all shipping materials with very strong UCV light before dispatching these from the laboratory. While probably unnecessary, it seems sensible when we have the facilities to easily do this.

Our thoughts and best wishes are with you and your families during this awful period, we hope you stay safe and healthy.

COVID-19 Update: Shipping Information, as of March 19, 2020

19th March 2020

In light of the uncertainty since the outbreak of Covid-19 I wanted to reassure you that, at present, we are operating as usual. The shipping restrictions which have been put in place only apply to people and not to goods so we are shipping normally.

The mail service we use does not require a signature and is apparently not subject to the same delays that are occurring for packages where a signature is required (for obvious reasons). We will be keeping up to date with any changes that may occur and will contact you if anything changes. If you do experience any delays, please be assured that we will always cover the costs of orders that arrive too late to be used.

If you have any concerns or worries, please do get in touch.

Keep well and stay safe.

Notice of Small Price Increase: October 2019

18th October 2019

Our mission, when we opened our doors over 6 years ago, was to make helminths available to all who wanted them, in a safe and affordable fashion. To that end, we have endeavored always to keep our prices as low as we can while ensuring the survival of our company. We have recently been faced with exceptionally large price increases from our vendors, ranging from accountancy fees to the cost of laboratory items to rent. Thus, we are now unfortunately in a financial situation that forces us to have to raise our prices slightly in order to survive.
Our new prices, starting Tuesday, October 22, 2019 are as follows:
  1. Vial of 5 – £21
  2. Vial of 10 – £25 pounds
  3. Vial of 20 –  trial dose £33 pounds; on subscription £30
  4. Vial of 30 – trial dose £40 pounds; on subscription £35
  5. Vial of 40 – trial dose £45 pounds; on subscription £41
  6. Vial of 50 – trial dose £57 pounds; on subscription £52
  7. Vial of 60 – trial dose £67 pounds; on subscription £57
  8. Vial of 100 – trial dose £95 pounds; on subscription £90

Changes to Shipping Dates: Effective August 19, 2019

21st August 2019

The laboratory will be changing our shipping schedule beginning this week. Going forward, we will only be shipping on Tuesdays and Thursdays:  all subscriptions that would have refilled on Fridays will be moved to Thursdays, and all other orders received after 9:00 AM GMT on Thursdays will go out the following Tuesday.  There are several reasons for us instituting this change, including that, in the longer term, it will allow us more time to research ways to improve our techniques and procedures, in addition to the research we already undertake in collaboration with Lancaster University.  If you have any questions, please contact Dr. Marc Dellerba at


28th September 2018

True to our mission, we have continued to make a Herculean effort to make HDC as affordable as humanly possible. Thus, in spite of major price increases in the cost of laboratory materials, we have not had a price increase in 3 years.  Unfortunately, in order to continue covering our overhead, we do need to raise them at this time.  As of October 1st, our new prices will be as follows.  As always, we will do our best to help those of you in dire need.  Thank you so much for your understanding.

vial of 10 – £22
