I have used them ALL........ summit I used before I knew it was an MLM and product that's not manufactured in an FDA approved lab. And I saw no results. Legend I use the day before a run or weekend of runs. It only lasts a few days but is a great, expensive, product. Pentosan I have used in horses with known issues. Worked well. All my horses get an adequan full series twice a year.  I have also use polyglycan and like it a little better than legend. It lasts quite a bit longer/ monthly vs only a few days. It all just depends on the horse. Are you treating a horse with known issues or preventative in a young horse. 

A ten year old who gets hock injections twice a year but really needs them three times and a five year old who would be preventative.

If it were my horses I would use monthly pentosan or polyglycan on the horse needing hock injections and an additional dose few days before a long weekend of hard work. For the preventative 5 year old , adequan would be perfect !

I have used them all. Summit I saw no difference.  And they have reps on every corner.  Adequan and Legend ,Polyglycan I saw results.  It depends on what your trying to accomplish but can get pricey.  For the 10 year old I would use Polyglycan or Movex. For the one as a preventative, I would use Adequan.  

Adequan is out of my price range this month. 

There is an adequan substitute called ICHON. If your vet will give you a prescription for it. And it's way cheaper. If budget is a concern, you might just go with pentosan , it's also way more affordable. 

I've used Legend and Summit. Absolutely no change with Summit so I went back to using injectable glucosamine. Very affordable. I pay $45 for 100ml. 

Yes, forgot about the Inj Glucosamine! Certainly an affordable option

If I am reading correctly ... It would cost you the same to inject 3 times a year in the hocks vs trying other things that you aren't sure work....

I have a similar 10 year old with arthritic hocks. She needs injections 2x yearly. Might be 3x but she just got kicked 2 weeks ago so she is out for a bit anyway. I do a loading dose of pentosan 2x yearly (march & september) to add additional support. As with adequan instrctions (not available in my country) vets are seeing greater results with loading doses rather than one shot per month

I've used Legend and Adequan, had ok results. Legend only lasts a couple days. My vet had me switch to injectable glucosamine and it's done jsut as well for me as anything. And significantly more affordable. My vet showed me some studies he's been following and they're showing that the gluosmaine is nearly equally as effective as the other options. And super budget friendly. My 100ml bottle is $50 and I do a 10ml dose every other week. My horses are also on Exceed 6-Way as well 

One thing to keep in mind with injections -- once you start joint injections with steriods you have started a countdown on how many times you will get results with the injections. Every horse may be different, but steriod injections in joints do damage each time they are administered. How many times your horse will get relief from injections depends on so many things. Sometimes one time is enough inflammation releif to let a joint heal and this is the right way to use injections. Sometimes they seem to be used multiple times a year as a necessity to get the horse to perform well. In that case the horse is probably nearing the end of carreer. I've heard different numbers from different vets, but generally if your horse needs injections 3 times a year then you most likely will only get relief for about 3 years. Maybe another year, maybe only 2.

Injectible supplements (glucosamine, legends, adequan, etc.) don't seem to lose their effectiveness over time, and cause no known harm as long as injections are given properly. 

I don't mind injections as needed, but I'd rather bute or banamine and give an extra adequan shot or two for race day/weekend than give steriod injections on a regular basis. Only my opinion. 

I have tried Adequan and Pentosan.

For Red (he has many issues), I do feel the Adequan helped him move a little better and not quite be so stiff for his warmup. My vet had me do the loading dose and then give a shot once a month. For about a week-ish after the monthly shot, is when I felt he had the most help from it. Of course, Adequan is expensive and I didn't want to give it more often b/c of it, so decided to try Pentosan this year. WOW. Wow. wow.  I did the loading dose and then continued one shot every 2 weeks. It probably took about 6 weeks total but he was no longer stiff at all for warmup. I was shocked, quite honestly. So guess who is never getting taken off it, LOL. Now that colder weather is returning, he has a little bit of stiffness for warmup but I'm going to chaulk that up to the weather.

For Shotgun, I put him on Adequan this year mostly for preventative. Since he didn't really have an issues, really, I have no idea if it helped. Made me feel better I was giving him something for his joints but that's about it. Later this year, he was diagnosed with a neck issue so I just started him on Pentosan now too, just to see if I notice anything for him. So to be determined.

Next year, I'll probably start my other horse Dexter on pentosan too, to see how he does. He has some lameness issues too. I was just blown away with the results with my horse Red, and it's dirt cheap compared to other IM injections.

What dose/concentration of Pentosan are y'all using? I used it before and was pleased, but I can't remember the concentration to reorder. 

I always use the pentosan Gold. I want to say it was 250/ml

I'll chime in on Movex in a few weeks.

Cool. That's what I was thinking it was last time I used it.

I know of a different joint supplement that is called GLC 5500MAX that I have had great luck with. It is very cost friendly. I was recomended it by a friend who was able to completely stop using injections on a horse that needed them 2-4 times a year by feeding this product. It also is a great preventative. The brand is Cutting Edge Performance. PLUS, they have a 30 day money back guarantee so if you aren't seeing the results you want and need you can get all your money back. That is why I was so open to trying it.(:

Equithrive is a feed through supplement.  Absolutely works.  Recommended by top lameness vets.  Vets that normally won’t recommend a feed through love this supplement.  It’s 130.00 for 60 day . 

I use the ICHON.  works fine on my mare

I've used Adequan (and Ichon - SAME exact thing but basically a "generic" and cheaper, I use it off label but also know what I'm doing, same great results, can get it off Chewy for cheaper than what most vets can when they're running their 30% off promo). Legend a day before the show, helps keep them comfortable being stalled all weekend and I can tell a difference in them. I won't use Summit - no reason to when Adequan is proven to work and it's the same price. Side note - MoveX is the same thing but 25mg "stronger". Summit is 100mg and MoveX is 125mg. 

Summit actually has a deal going on where you can join for $49. I'm starting my marw on it as soon as it comes in. 

Movex is having a Halloween special .  Buy any product and get one Vial Free.  You have to enter the code when you check out.  Runs through midnight tonight 

I ride mostly younger horses.  I have not ever used Legend, it isfor  lubrication and short acting dosed for weekend use mostly and expensive for what my needs are which is usually preventive.  I have used Adequan on a really nice futurity/derby mare I had.  She bled the summer of her 6 year old year and it was first thing I changed due to its small risk factor of bleeding.  I then went to feed throughs MSM and then GLC.  My problems is I feed very little and when they are turned out I only use equipride tubs.  I was introduced to Summit last January.  I have a navicular mare I had problems keeping happy on os phos and coffin joint injections for very long.  I used it on her first thinking it would help make her injections last longer,  I had so much sucess in her that she has been maintained strictly on the Summit and MSM.  I have everything I own on the Summit, yearlings up to my broodmares.  It removes inflammation from all over, not just in their joints.  I feel it is an amazing preventative for all ages for many things, gut issues, joint issues etc.  If anyone would like my specific sucess stories feel free to message me  I am more then willing to answer questions. 

How does summit help gut issues?  It is a joint supplement.  I also saw where someone claimed it cures bleeding. I tried it and my horse had a reaction to it.  Never really noticed a difference.  It was being used as a preventative/maintenance. Are you a rep?

I used to use just polyglycan until 18 mos ago when my vet had me switch my oldee mare ti pentosan. 

HUGE difference. I know that Summitt is awfully popular at present or seems to be, but I won't be changing what works. If it ain't broke, don't fix it, amirite?

I have not used any of the others mentioned. 

it removes inflammation from all over the body not just in joints.  as far as bleeders it will help with lung inflammation.

It is better to use something that is for gut issues.  It is not going to help Ulcers or as one rep said colic. As far as bleeding it’s not going to heal the lungs or keep a horse from bleeding.  To imply it does is not good business when it has not been proved.  If you have documentation where it has been researched I would like  to see it.  Not just a rep saying it does.  By actual professional like a lab.  Can you supply that documentation?  Butte also decreases inflammation but it is not reccomended for ulcers.  

I haven't logged on or posted in years, but I have been doing some research on choosing a supplement and wanted to see what the peeps of BHW were saying.  I came across this thread and thought I would chime in.

I used Summit last fall with a lot of success.  No, I do not sell it.  No, I will not sell it.  I really don't care for MLM's and generally avoid them at all costs.  Having said that I decided to purchase Summit after discussing my mare's issues with a very good friend (who I trust) that sells Summit.  
The change that I saw in mare was amazing.  The back story is she foundered a few years ago and even though she has made an almost complete recovery, it's still a constant battle keeping her sound.  Or as sound as she can be.  I have great vets and a great shoer that have kept her going. 
I also use ice, Magic Cushion, Soft Rides, Back On Track, Previcox. The whole gammet.

Not only did her pattern runs improve, but she also got faster. 5D to the 3D in some big, tough races. (before foundering she would be in the 2D) . One of the best things was I was finally able to take her off the Previcox, something I have been wanting to do for quite some time. 

Summit was a waste of money on my two.  They are now on Previcox and are doing much better.
