Anonymous Journey

GC Biosciences has a varied client list and some of our clients prefer to remain anonymous and we respect that right.

“I am on a journey with Calum (Gore) who a friend recommended I should contact when I was diagnosed with IBS.  Although we are not at the end of the tunnel yet, I feel so much better and we have dealt with so many issues.  Calum has coaxed me through difficult times with different supplements, diets and explanations with such care and consistent encouragement and positivity.  We have come such a long way and week by week we have addressed different issues and the change in my well-being and confidence is huge.

I have been grateful to his always being on the end of the telephone for me and he visited me at home one time when it was difficult for me to get to see him.  I particularly appreciate that Calum is somebody who really does want to help me and cares about the problems I am having.   Sometimes my symptoms maybe small, but feel huge to me, and Calum is never belittling of my worries and gives so much thought and time to making strides forward avoiding troublesome side effects for me to cope with.

I also thank Calum for explaining his findings in a format that I can understand.  Thank you Calum and I am sure it will be as much as a relief for you as it will be for me when we reach our goal….  Importantly and empathetically you have been very generous both with your time and financially.”


Luke Dalmedo’s Journey

I was recommended to Calum by a very knowledgeable friend as I had been suffering from very bad IBS and GERD (reflux) symptoms for some time and it was really starting to take a strong hold on my life, it ruined my lads group trip to Vegas and was also effecting my start at university in the hope to become a PE teacher.

When I first spoke to Calum, he explained my problems in more detail and recommended I get the food sensitivity test and also advised I get a couple of different supplements to start me off, all the advice which he didn’t charge for.

I eventually got the test done and the results were very shocking in regard to the foods I can’t eat which I ate most days (black pepper, potatoes, oats etc). So, I went on the first diet and supplement plan. Which were both altered at different phases of the plan.

My reflux was already getting much better within the first month of using the HCI supplement and after 2/3-month mark, I started noticing serious positive changes with my gut (first normal stool in a long time, no pain in my stomach which was 24/7). Before taking this on, I was so sure I was doomed and IBS/GERD was something I would have to live with, but I was so happily proven wrong.

What I was specifically impressed with Calum was his approachability in that he offered to speak on the phone or meet up in person to discuss what we are going to do next or to talk about a problem I had etc. Baring in my mind I was only ever charged once for the food test during my whole time working with Calum

Also, his confidence helped me in regard to the psychological aspect, after having a ruined Vegas trip, my brother had offered to take me again which I didn’t want to accept as I didn’t want to waste his money if I wasn’t well enough. Calum assured me that by that time I would definitely be better. This turned out to be true and I ended up having the best time, drinking until the early hours every night and not eating the best food but because my gut was so strong through sticking to the course, I had no problems. I sent him a personal message when I got back thanking him for all his help. 2 years later I’m as good as I’ve ever been, i would recommend GC to anyone with digestive issues, can’t say enough how glad I am to have come across them.


Simon Herbert’s Journey

Working with gore bioscience is the most sensible move I’ve made towards my health goals, after suffering with Ulcerative colitis and pursuing a fight career, there’s no room for messing about. I got my individual testing done and now I’m back on track to feeling like I used to. Calum’s there when I need any advice and he explains why, what and when which makes my life less stressful.

Lucy Walton’s Journey

It may sound dramatic to some, but the team saved my life. I had been facing numerous illnesses for two years with a very serious decline end of 2013, the knowledge held by the team has been invaluable in my diagnosis and recovery. After testing using industry leading methods, we identified the root causes and I’m finally getting well!! I cannot thank them enough for not only taking a personal interest in my health and wellness but for giving me my life back.

Franchesca Shearer Client Journey

Francesca Shearer’s Journey

Working with GC Biosciences has hugely changed my life. I have suffered from Crohn’s Disease for 5 years and have been on constant medication during this time, with little success. I have struggled to reach my training goals despite good training and what I thought at the time was good nutrition. Within a week starting my new diet I began to notice the effects on my body. I have visibility reduced inflammation and lost 5kg. I now sleep through the night and experience improved mood. I am stronger, leaner and have more energy than ever before. Most importantly I have been medication free for 2 months, with no return of previous symptoms. Where doctors failed, the team have achieved something I did not think possible.

Fiona Client Journey

Fiona Dobb’s Journey

I can’t say how pleased I am and that I found the team after 3 years of suffering a range of symptoms misdiagnosed by GP’s and various consultants. I have literally been back and forth on hospital visits to try and establish the cause of my chronic inflammation which has significantly impacted my life to the point that some days I couldn’t even hold a pen due to joint pain. The report was extensive, and it has highlighted issues that never came up with my consultant and a further follow up call from the guys gave me a detailed in-depth explanation of what the results meant and the next steps. A healthy eating plan was put together and advice on all the nutrients and vitamins my body was lacking. Thanks a million for all your help and advice. I can’t recommend you enough.
