GcMAF oral supplement spray (or eyedropper) for animals

This spray contains GcMAF suspended in a neutral saline solution. The 25ml bottle delivers approximately 175 sprays which can be administered daily based on your animal's size outlined in the instructions below. Suitable to use on all vertebrate animals, the spray is a powerful immunotherapy solution designed to assist a wide range of conditions affected by the immune system. These may include tumors, skin growths, viruses, infections, gum/mouth/dental issues, blood-borne conditions, inflammation, gut health and other non-topical conditions. Simply spray under the tongue (sublingual) or gums/mouth tissue (buccal) to supplement GcMAF directly into the animal's blood system. For lymphatic, topical, skin or muscular issues (arthritis) we do recommend using our gels instead.

Available as an eyedropper dispenser - For very small animals like mice, birds and rodents you may wish to choose our eyedropper option before adding this product to cart. This makes it easier to administer the formula into the animal's mouth.

  • Made from bioidentical GcMAF suspended in a neutral saline solution
  • Contains 175 sprays, each delivering 286ng GcMAF for an aggressive approach

Dosage & usage instructions

Spray under animal's tongue (sublingual) or directly to gums/mouth tissue (buccal) according to your animal's size listed below. Make sure the animal does not consume food or liquids for at least 15 minutes before or after application. Doing so ensures the spray does not bind to food/liquid particles where it will be digested and destroyed by acids within the stomach.

  • 0-2kg: 1 spray/drop once a day (will last for 180 days)
  • 2kg-100kg: 1 spray twice a day (will last for 90 days)
  • 100kg – 200kg: 1 spray three times a day (will last for 60 days)
  • 200kg +: 2 sprays twice daily (will last up to 45 days)

How is the spray different to the gels?

This spray contains the same GcMAF formula used in our gel products, but instead of being suspended in a glycerin base, it is diluted within a neutral saline solution. This preserves liquidity making it suitable for sublingual/buccal delivery. Simply spray under the animal's tongue, gums or around inner mouth tissue for effective absorption through the thin layers of tissue into the capillaries/blood. This is a very effective way to supplement GcMAF to the animal's broader blood system and connected organs and tissue. Unlike our gel products, the spray should NOT be applied to the skin as it does not contain special ingredients which allow it to be transdermally absorbed through the skin's protective layer like our gels do.

Spray ingredients & manufacturing information

  • Pure GcMAF
  • Saline solution (salt water)

All GcMAFpets products are produced in an Australian GMP certified laboratory. Unlike other manufacturers, our GcMAF formula is not derived from human or animal serum. Instead we use a raw bovine colostrum base which undergoes a unique process to produce pure GcMAF. This is tested to be 100% biodentical to the GcMAF naturally produced within healthy vertebrate animals. All ingredients are natural, allergenic-free and ethically produced.

Treatment approach length

It is recommended to use the spray daily for at least 2-3 months. After this you may wish to continue use depending on the results experienced by the animal. More aggressive issues may require continued treatment after the initial 2-3 months, whereas minor conditions may clear up within the first few months (or even weeks) and further use is not required. There are many factors which may affect the timeframe and results experienced across different animals and types of conditions. By committing to at least 2-3 months ongoing treatment, this will allow sufficient time for the supplementation to have an effect even on severely compromised immune systems. The ultimate goal is not to keep using the products forever, rather to address the current issue and restore the animal's ability to naturally produce their own GcMAF as a long-term solution.

Instructions for use

Please use the recommended number of daily sprays (listed below) based on your animal's size. The formula should be sprayed directly into the animal's mouth under the tongue, on the gums or internal mouth tissue. Avoid spraying on the teeth and ensure the animal does not eat or drink for at least 15 minutes before or after each application. One application/spray is dispensed by gently pushing the lid down to spray a mist in the desired area.

Sprays per animal size guide

  • 0-2kg: 1 spray once a day (evening is best)
  • 2-100kg: 1 spray twice a day (morning and evening)
  • 100-200kg: 1 spray three times a day (morning, lunch & evening)
  • 200kg +: 2 sprays twice daily (morning & evening)

Other recommendations

  • Ensure the animal receives sufficient Vitamin D, either through their diet or via sufficient exposure to sunshine (if applicable). GcMAF is a Vitamin D binding protein so this helps transport it throughout the body. It is also required for the production of new GcMAF within the body naturally once everything is rebalanced to a point .
  • Make sure the animal is relaxed and then gently open their mouth to spray inside with minimal resistance
  • If you are having troubles spraying under the tongue, it is perfectly fine to open their mouth even a little bit and spray directly on the gums closest to the mouth opening. For resistant animals this is the best approach.
  • Unlike our gels, the spray is not intended to be used on the animal's skin as it will not absorb through the skin's penetrative layers on its own.
  • If your animal's size necessitates only using 1 spray per day, the best time to do this is of an evening before they sleep as this is when the immune system is at its most active
  • A healthy diet and consuming plenty of water is important for any type of recovery from illness, so ensure you are feeding the animal a veterinarian recommended food and they have plenty of water.

Storage & precautions

  • Expiry: Will last for 12 months unopened and 6 months once opened (if kept refrigerated between use)
  • Avoid contact with the animal's eyes or open wounds
  • Keep out of reach of small children and store in a safe place


  • GcMAF: colostrum-derived bioidentical formula
  • Saline solution (salt water)

Product packaging

This product is packaged in a plastic bottle with a screw-on spray lid to dispense the formula. It will provide approximately 175 spray applications per bottle if you push down with normal force on the nozzle. Spraying too hard or too lightly may mean you receive slightly more or less than the approximate 175 applications, so please note this is a guide only. The expiry date will be printed on the label, however please note that once the lid is opened this product will only last 6 months if kept in refrigerator.

I have had a growth on my nose for some time, I have been using this cream for a month and the growth is no longer there, so I applied it on my dog who had a lump on his ear, I noticed the lump became smaller and now is not there anymore. I am truly amazed at this cream.

Billy, US - Cat

Hi folks, Just to let you know wee Malky the rescue cat is doing great so far as you can see by the attached picture. Looking very healthy and put all of his weight back on and eating and doing the toilet normal and chasing after the other cats etc. Cut his insulin down by half at beginning of January and then after a couple of weeks stopped it altogther and he has been fine ever since. Havent been near the vet with him since they gave him only a few weeks at most nearly a year ago now. My friends brother has been doing great with the GcMAF as well - his count went down from over 170 to under 30 so he is buying some more from you to hopefully get rid of it for good - may have bought it already. Malky helped convince him to go down this road when they saw how great he was doing using this.

Helen M, Australia - Cat

I have a cat who had a growth on her ear, we took him to the vet and he said it was skin cancer and had to be removed by operation I had used GcMAFplus on my self for various issues and thought it would be great to use on our cat so we purchased the new pet gel. We applied the gel to the cats ear for one month, to our amazement when we booked in to ask the vet to check out how the cat was going, he could not believe it that the skin cancer had disappeared. Our cat is part of our family so now we all take GcMAF daily, we have our cream and spray and we now have the pets gel and spray. We want to keep the cat healthy so the cat is on a daily dose of GcMAF and has not had any health issues or growths since I highly recommend GcMAFpets for anyone who would like to keep their pet healthy or if the pet has a health issue, it helps them stay healthy

15,000ng GcMAF Gel For Large Animals

Harold T UK - Dog

We knew that GcMAF was a great product for humans as we were using it to keep ourselves healthy. But we did not know about the pets range. Our vet was testing it out on some of his clients pets and he found it was assisting with many health issues that the pets were having. Our pet suffered from ulcers in his mouth, obviously from what ever he was eating when we were not in eye shot of him. We put him on GcMAFpets for two months initially once a day, to our surprise he does not have ulcers in his mouth, his immune system has kicked in by using the GcMAFpets and is keeping him healthy

Ana K Germany - Dog

We have a Doberman that had a growth on his tummy, the vet said it looked suspiciously like a tumour and he wanted to do more tests. We had decided to use GcMAFpets as we did not want and invasive procedure. We applied GcMAFpets on our dogs tummy area and also gave him GcMAFpets spray, within 3 months the growth on his tummy was completely gone and he was as healthy as ever. We continue to use this product on our pet and now we have bought the human GcMAF products for our selves – seeing that it had such a positive effect on our dog

Martin G, Spain - Dog

We have a 5 year old golden retriever, he has had gum issues for many years, we have the vet clean his teeth regularly but it distresses him and he seemed to have gum disease. We did not want him to lose his teeth and knew that the bacteria in his mouth was causing him distress. We used the spray for several months.When we first started using it directly onto his teeth and gums, it was about two weeks and the inflammation seemed to have gone down. We now continue to use the spray with him daily as he seems healthier and happier and there is no more inflammation on his gums. We will continue to use this products as it keeps our dog healthy
