    Pure Lysine is rated 4.5488 out of 5 by 82.
    Rated 4 out of 5 by from Not on for too long I mainly bought this because I was trying to put weight and muscle on my 3 year old appaloosa who has such a hard time with muscle and weight. I only used this for a month so I cant accurately judge the product. Dusty, my horse, ate it right up every time so I had no problems there. Maybe if I were on it longer I would have seen results, but because I switched products I cant say.

    Rated 3 out of 5 by from Winderful product but I've been a good customer for years, and I see several people on a regular basis to whom I have recommended Lysine 4-pound buckets which were $24.95 for a long time. We all meet on fridays often. But I will be recommending the exact same lysine in 4-pound buckets from either of two sources--shipped cheaply--I now pay $21.85. If your price comes down, I will recommend you again, otherwise, I will share my good news of 4-pound buckets for $21.85 with its inexpensive shipping. rohansel, Pennsburg, Pa

    Rated 5 out of 5 by from Lysine great supplement for aging muscles I have a 30 year old Pinto gelding. When I bought him a couple of years ago, he had no muscle behind his shoulders and a pointed butt, no muscles there either. I read that the coastal bermuda in our area is very low in lysine which is needed to help maintain muscle mass in horses. So I started him on the lysine and a smartpak joint supplement. He is a beautiful 30 years young. I still ride him, and he loves to be first when going on trail rides. He still has the spunk of a 3 year old. Sometimes when I let him out to run in the arena on his own, he will actually buck and run! I love to see him this heathy and happy. We also had a Strangles breakout at the place were I board. Lysine helps with viruses, I think. Rio did not get the Strangles. He stayed perfectly healthy through the whole process. Thank you so much!

    Rated 5 out of 5 by from I tried the pricier stuff...this works better! I have a halter bred gelding that just wasn't filling out like I wanted him to. I wasn't looking for that "halter stallion" look, but I wanted him to look like the stocky Quarter horse that he was. I have been using it for about 5 months and I can see a difference. ( I could see a difference after 2 months) He is more filled out on his top line, his hip, neck and shoulder! He looks natural and healthy! He is nicely muscled! I tried the more expensive stuff, but this just works BETTER! He places well in gelding halter classes locally!

    Rated 4 out of 5 by from Seems to work My gelding does seem to be gaining lean muscle very well (but not the bulk I was hoping for-and that he is bred for) He eats it just fine. Its definitely a good value!

    Rated 5 out of 5 by from Great Natural Way To Fill Out!! I noticed results around the second week. My 7 year old show gelding was really filling out over his withers extending into his back, I was getting shape over the top line and even getting more grooves down his rear quarter. I love this supplement. He doesn't act hot or wound up, just is putting on shape in the right places, from food he's already eating. love this supplement, he will never be without it, from this point on.

    Rated 3 out of 5 by from Ahh if only I really wanted my mare to eat this -- she was going into heavy work for the first time and I wanted to have all the amino acids covered, but she refused to eat it. She'd pick her pan up and dump all the grain out :( and when I mixed applesauce in with all of it she outright refused it.Alas, on to the next challenge!

    Rated 4 out of 5 by from Improves Hoof Health My Appy/Draft cross (@13 yrs.) has been barefoot w/ a natural trim since I've owned him (2 yrs.+) and has done well. We participate in a variety of activities. However, he suffers a laminitic type reaction to vaccinations w/ accompanying tenderness and loss of concavity. The 2nd time this happened, my trimmer suggested supplementing with l-lysine (along w/ milk thistle for detox) and he recovered much faster. His overall hoof (incl. frog) quality is better also. I check his feet daily & rasp him weekly between trims, so I am very aware of any changes to his feet. He also seems to be feeling and moving better in general. I have also seen similar improvement in 2 other horses on the farm who were much worse off. All 3 are easy keepers and so far this has proved to be a simple and economical way to supply them with a vital nutrient w/o compromising their health in other ways.

    Rated 5 out of 5 by from Worth the money! I have a 3 1/2 year old 16.1hh Hackney Horse filly, who while I was recovering from an injury left unridden and lost her muscle mass. She has been doing drastic growth spurts and so without being ridden became rather straggly. I wanted to find something that would encourage the muscle w/o it being unnatural. I already knew she was healthy, however I also knew that her body was expending most of its energy on her bones and tendons. I tried this product because it was relatively inexpensive and would appear to be something that could help a youngster. Within a week of her going on it there was a large difference. Hollow haunches filled out, her topline came back and she was very happy. For this price she can stay on it. I then put my mare on it and the same thing happened within a week. This product is worth the money!

    Rated 5 out of 5 by from Fantastic product - great price! We bought an APHA gelding (QH stock type crossed with Jockey Club mare) and he was about 300 pounds under weight. After struggling with getting him to add weight withoutmaking him hot, some research brought me to this product. Pure Lysine has made all the difference. He's gained and held weight and muscle tone that I never thought possible. My Dad and Uncle commented this Fall that he's filled out more than they thought possible given his frame and thoroughbred blood. Even the farrier commented a couple of weeks ago about his condition. (This is all after about six months on Pure Lysine.) So, due to success with Dutch, we put my 30 year old gelding on it this winter since an illness caused him to lose weight just before Thanksgiving, which is not good for an aged horse that has Cushings and facing a WI winter. Well, he's actually gaining his weight back and is happy too - he ran and bucked along the paddock fence with a youngster while riding by a couple of weeks ago. Great bang for the buck! =)

    Rated 5 out of 5 by from Licks the bowl clean I started this product along with weigh gain and my mare loves it, this doesn't even have to be mixed in grain. She will eat it straight out of her dish.

    Rated 5 out of 5 by from Great Product !! I have to say im very pleased with product, had an orphan APHA (thoroughbred/paint) colt who got so underweight after his dam passed away from colic when he was 1 1/2 old, no matter what he was fed he just would not put weight on or even grow (he probably ate more then any horse in the entire barn). Got so bad that a random passerbyer had actually called animal control on him. Had everything from the vet so it came to be nothing, but thats when i started to look for something that would be a good for him other then his grow colt supplement and calf manna that would be safe for a growing foal.Started this product when he was about 3 1/2 months old and after about 3 weeks started seeing a change he started filling out and not only putting on the weight but keeping it as well as growing. He's now 7 months old and over 13hh and is still maintaining his weight and doesn't have a rib to show, might actually reach the full potiental he was born to grow with both his sire and dam being 17hh. He now is only on Pure Lysine and Grow Colt and is holding out great. Would Definately Recommend this product, it worked wonders for me.

    Rated 5 out of 5 by from Quality Product I am very pleased with the Lysine that I purchased through Smart Pack. I researched other Lysine Supplements and SmartPack beat the others in quality and price. I have been feeding the Lysine to a 23 year old QH gelding and 34 Welsh Mare and in less that 3 weeks there was a noticable improvement of their muscling over their topline!

    Rated 5 out of 5 by from Muscle! I can't believe how much muscle my Friesian has put on since starting on this product! He seems so much taller to me with the improvement in his topline. Very happy! Great result for little $'s.

    Rated 5 out of 5 by from A Product That Works Wonders! I have a 17'2 Oldenburg Warmblood jumper athlete. When I first got him he was neglected and needed to put on weight and get back into shape. I had him on a special program with lots of supplements to help him gain weight and an exercise routine for the muscle development. When he only had about 200 more pounds to look like a 4 foot jumper, I really wanted him to have some flashy Warmblood muscle definition. Now, my horse was being worked almost every day during this weight gaining process. But Pure Lysine REALLY made a difference! In about 2 weeks I noticed muscle definition in places I never thought would get there for a while with time and exercise. He was feeling great and wanted to exercise for over an hour! It also helped with muscle soreness after a long ride or jumping lesson. I am thrilled with this product and will use it for a lifetime! I started out with 3 scoops of the product, when my horse looks healthy I will probably cut it back to 1 scoop. I definitively recommend this product for athletic horses that want a flashy muscle definition and horses that need to put on weight without consuming to much grain and supplements. A great way to get results without having a "hot horse."

    Rated 3 out of 5 by from Lysine not great I expected by the description given that the Lysine would promote muscle and healthy hooves. I haven't really seen any changes in the horses. They don't really like the taste either.

    Rated 4 out of 5 by from Once you get past the smell... This product smells completely rank, but once you get past the smell, I think the results in improving your horses' coat and build are worth it.

    Rated 5 out of 5 by from Great Choice I purchased Pure Lysine on the reccomendation of a fellow barrel racer, whos horse also had a deteriorating top line. I was told about how pure lysine had brought back the muscle and evened hid back out. I decided to try it on my mare. She was only on it for 2 months (I don't ride in the winter, so she isn't grained), and I noticed a definite change in her topline. She will definitely be on this again in April!

    Rated 5 out of 5 by from Good product I put my horse on this as a recommendation for treating head shaking syndrome (HSS) since lysine counteracts the herpes virus. My horse is on 20g/day and eats it all (but he is not a picky eater). He has been out of work for about 1.5 months and still is in good condition, and I think this product is helping him keep his muscle tone while on "vacation". It's relatively cheap to feed which is a plus as well.

    Rated 5 out of 5 by from Seeing Results Already Don't know how fast it really works, but it looks like my horse is already benefiting from the Lysine. I can visably see where his muscles are starting to show definition.

    Rated 4 out of 5 by from Lysine is good for muscles My horse is about 30 years old. When I bought him, he was malnourished. Since then, I have added some supplements to his diet. Lysine is one of the supplements that I added due to the poor quality of the grass hay here in Amarillo, TX, and also, due to the fact that he is in a run instead of out on pasture. I feel that the lysine has contributed to the development of muscle in his hind end and back. His sagging spine seems to have lifted somewhat. I did not expect him to recover from this kind of deterioration. However, he is running through the arena now, and actually bucking, something I have never seen him do before. It's like he is saying, "I feel GOOD!"
