Our Concept for Muscle XL

Fast and Effective Results

Muscle XL works so quickly because it is the perfect ‘muscle food’, with extra nutrients that allow muscles to quickly absorb and use the quality protein that Muscle XL provides.  First results in better topline and muscle tone are normally seen within 10 – 14 days, especially if fed within 15 minutes after exercise, like a human body builder’s protein shake!  Even a 10 minute walk to get the muscles warm and ready to absorb the ‘food’ that Muscle XL provides is enough to maximise results in a short period of time.  You can feed it in the nightly feed (it will still work), it will just take between 5 – 10 days longer to see a good difference.  

For Rehab, Repair and after Rest

Muscle XL is an ideal supplement for horses undergoing rehabilitation from muscle injury, offering targeted nutritional support to aid in recovery and restore lost muscle mass.  It is particularly beneficial to build stronger back muscles and top line to support lower back or sacroiliac weakness, as well as in the recovery of the muscles after a tying up episode.  Muscle XL helps horses quickly recover strength and topline after rest or a spell when they are returning to training.  

No Fizz & Competition Safe

Muscle XL will not make a horse ‘over-strong’ or uncontrollable with fizzy behaviour as it does not contain sugar or added energy.  Muscle XL does not swab or contain banned substances and does not contravene the Rules of Racing or FEI Competition, but rules prohibiting the use of any pre-race supplements within 24 hours of racing should be followed if applicable in the local jurisdiction.

Muscle XL has helped Benny build up his top-line and maintain a good shape for the show ring.

I just want to thank you for your fantastic products that I have used religiously for the past couple of years since buying my horse S.L.M Signature.

Benny came to me with some stress issues including stomach ulcers so he refused to eat. I experimented with a few products experimented with a few products before taking on advice from my coach, Susan Elekessey to try Mag-E, Gastro-Coat and Muscle XL. The ulcers cleared up quickly with Gastro-Coat. I manage his stress with Mag-E, he is much more relaxed at events and at home now making him so much more reliable and safer to handle.

Muscle XL has helped Benny build up his top-line and maintain a good shape for the show ring. He is winning and shining in the Hack ring to Royal Show level and making all my dreams come true.

Thank you John and the team for your amazing products and advice!

Being a harness racing trainer I use many of your products, but one of the best on the market is the Muscle XL. The horse pictured had a very sore back and muscle atrophy, but within 6 weeks on Muscle XL he built top line and strength and has been placed in his last 12 starts. He is a much happier horse. Your sacroiliac exercises and advice have also helped him a lot.

Can I give Muscle XL if my horse is not in work?

In most cases, we recommend supplementation of Muscle XL be combined with exercise to help achieve the most impressive results.  Even light exercise, such as 10 minutes of hand walking, is enough to get the muscles ‘warm’ and ready to uptake the specific muscle foods which Muscle XL provides.

However, many horses lack the necessary high quality protein and particularly, essential branched chain amino acids (BCAAs), in their regular diet to maintain muscle health and top-line.  Muscle XL can be used as a normal in-feed supplement in times of drought or poor feed quality, or for older horses which struggle to maintain muscle bulk, commonly due to reduced ability to digest protein as they age.   A daily half-dose of Muscle XL can meet the increased needs for quality protein to ensure optimum health and vitality.

Horses suffering from muscle injuries requiring rest and rehabilitation may also benefit from a supplement of Muscle XL daily to reduce the risk of muscle wastage and top-line loss, although daily light hand-walking is recommended to help target the benefits of Muscle XL.

Does Muscle XL swab?

Muscle XL does not swab or contain banned substances and does not contravene the Rules of Racing or FEI Competition.  This product is a nutritional supplement to support the health and well-being of a horse. It does not artificially enhance the performance of racing or competition horses. Rules prohibiting the use of any pre-race supplements within 24 hours of racing should be followed if applicable in the local jurisdiction.

How can Muscle XL help my horse during rehabilitation from an injury?

Some horses need extra support to build muscles when suffering from lower back pain, sacroiliac strain, lameness episodes, severe ‘tying up’ or other injuries requiring extensive rest and rehabilitation.

Muscle XL is a popular supportive supplement for muscle health and function in horses which have suffered a muscle strain or injury which requires improved muscle tone and strengthening of weak muscles.

In combination with light hand walking or stretching exercises, Muscle XL can help regenerate musculature to support long term weakness or soundness issues.

How does Muscle XL help with recovery of tired muscles?

Muscle XL can be used as a targeted supplement in all horses when required for recovery after intense training sessions, hard competitions or endurance rides where muscle energy and antioxidant replenishment are paramount.

Muscle XL contains a special blend of branched chain amino acids (BCAAs), L-glutamine, and antioxidant vitamin E as a natural, high potency form, which assists the natural repair and recovery process after muscles have been stressed from intense exercise.

Muscle XL is recommended to be used as a top-up supplement for 4-5 days before and after hard exercise or competitions to build a reserve of muscle energy and then help regenerate tired muscles.

How does Muscle XL work in relation to my horse’s diet?

Muscle XL is designed to meet the needs of specific muscle-active amino acids and high quality, essential proteins that horses require when in regular training and competition.  The synergistic nutrients in Muscle XL, including vitamin E and MSM (organic sulfur) are also often limited in equine rations and have roles in antioxidant protection of muscles to ensure optimum strength, stamina and recovery. Thus, Muscle XL is formulated to be a targeted supplement to help increase lean muscle mass, top-line and muscle tone.

However, it is recommended not to give multiple high protein supplements to a horse.  Often owners add too much ‘non-essential’ or ‘common’ protein supplements to a ration, which can reduce the top-line building affect of Muscle XL.  This is because Muscle XL features a specific ratio of selected amino acids and proteins for the best results.  Thus, a diet with adequate, but not excessive protein, supplied by general feeds, hay and grass, commonly gives the quickest and most effective results with Muscle XL.

If you require more information on tailoring your horse’s ration to ensure top-line and muscle build is optimised, contact our Kohnke’s Own Nutritional Advisors by email to info@kohnkesown.com for FREE advice and a detailed ration analysis.

How long before I will see results?

Muscle XL quickly and easily helps builds muscle in horses lacking proper top-line and muscle tone.  Normally, initial results will be seen in 5-7 days, although individual results may vary, particularly if the horse is severely lacking in muscle tone.  Working the horse at a light to moderate level to ensure the muscles are warm, before giving Muscle XL as a targeted supplement within 15 minutes of this exercise, will also ensure that the benefits of Muscle XL are visible within this short timeframe.

Is Muscle XL used long term?

We recommend that Muscle XL be used as a daily course for 2-4 weeks until you are satisfied with your horse’s top-line and musculature.  Afterwards, Muscle XL can be used every month for 5-7 days, especially after hard work, to ensure continued muscle health, top-line and optimum recovery.

However, for horses with increased needs for muscle health and under stress of intense muscle-related performance, such as endurance horses, racehorses or high performance equestrian horses, Muscle XL can be used as a long term daily supplement without ill-effects.  For these horses, Muscle XL is particularly beneficial to help ensure strength, stamina and recovery after intense training and regular racing or competition.

Isn’t top-line achieved through exercise?

Regular exercise is essential to maintaining a fit and active appearance.  However, many horses lack the specific levels of some amino acids, particularly the branched chain amino acids leucine, isoleucine and valine, which encourages the generation of lean muscle mass.  A supplementary course of Muscle XL, along with regular light to moderate exercise, can help to quickly and easily build top-line and muscle tone with impressive results.

Horses in hard or intense work put their muscles under increased stress to enable optimum performance during regular training, racing or equestrian competition.  For these horses, Muscle XL is an excellent daily supplement during the competition season, to ensure optimum muscle function, strength and stamina is maintained, even on premium feeds with added lysine or protein.

What makes Muscle XL effective?

Muscle XL contains a concentrated, superior balance of BCAAs compared to other essential amino acids, in a high protein (79% amino acids and protein) supplement. This specific amino acid profile helps builds lean muscle and not fat or excess condition.

The optimum profile of branched chain amino acids, (BCAAs) preferentially absorb and target muscle replenishment and bulking processes.  These BCAAs and other essential amino acids are able to incorporate into muscle fibres, particularly after light to moderate exercise, when the muscles are warm and can uptake the muscle ‘food’ provided by Muscle XL.

Muscle XL also contains a source of glutamine for muscle energy, plus synergistic ingredients to help the amino acids be converted to muscle fibres, including MSM and vitamin E for muscle recovery processes.

When should I give Muscle XL?

Muscle XL can be mixed into the normal main meal or hard feed each day until the desired muscle build and top-line is achieved, normally daily for 14 – 30 days. Then continue Muscle XL as required to maintain muscle bulk, usually as a top-up course for 5 – 7 days each month or after hard exercise or competition. 


Best results will be obtained with regular exercise, especially if Muscle XL is given within 15 minutes after exercise when the muscles are warm and ready to absorb the ‘muscle food’ provided by Muscle XL.  Muscle XL can also be mixed into a paste with an equal volume of water and supplemented over the tongue in an oral dosing syringe. 

Which horses can benefit from Muscle XL?

Many horses lack the necessary high quality protein and particularly, essential branched chain amino acids (BCAAs), in their regular diet to adequately build muscles and strengthen top-line.  These horses may look underprepared, lack stamina or recover poorly after hard work.  Owners may also find it difficult to rebuild and maintain muscle bulk and fitness in a horse after a spell, rest, injury or increase in the training level.  

Muscle XL is particularly recommended for competition horses to boost top-line, muscle tone, fitness, strength and stamina without fizzy energy.  Muscle XL is helpful when horses are flat, lack energy or stamina in multi-day competitions, cannot handle quick turnarounds or struggle when increasing training load.  After desired muscle build and top-line is achieved, Muscle XL can be used intermittently to maintain a fit and active appearance.  

Muscle XL is also highly beneficial for building good muscle on young horses, particularly yearlings or horses for sale, horses in early training or after a spell.  

Muscle XL is suitable for horses of all ages and levels of training as a targeted supplement of muscle-specific ‘foods’.  

Will Muscle XL make my horse fat or fizzy?

Muscle XL has a specific blend of protein and amino acids with no fillers or other nutrient which would cause weight gain.  Muscle XL is formulated to build lean muscle mass and a stronger and more defined top-line.  Even in lightly worked horses, Muscle XL can be used to help generate a nicely muscled presentation without excess fat or fizzy energy.
