Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum.

IV Polyglycan injections in place of Adequan and Legend?

  • IV Polyglycan injections in place of Adequan and Legend?

    IV injection of Polyglycan is considered off label use as the drug is used for post surgical joint lavage. My vet has recommended its use as a once a month IV injection to replace Adequan and Legend. He uses it on his high performance horses and suggested I give it a try.

    I am not treating any problem but rather trying to offer a good alternative to feed through supplements for my hunter. The price is about a third of monthly Legend and Adequan injections.

    Has anyone else tried or heard of such use of Polyglycan?

  • #2
    My vet also recommends this as an alternative to feed through supplements.

    On his recommendation I used it on my last horse (a Morgan--TL dressage, trail, pleasure to ride kind of guy) when he was recovering from a back injury caused, we think, by a slip and/or fall in an icy paddock.

    I've also used it on my new horse as a "preventative" when he is in hard work. I look at it this way, the shot costs me the same as a month's worth of a top supplement, and realistically I have no idea how much the supplement actually is absorbed.

    That said, I'm not sure it is an exact replacement for Adequan or Legend, and if my horse had a diagnosed injury or arthritic condition I might choose those instead.


    • #3
      we just had a horse get iv polyglycan yesterday. we'll see if it makes any difference. the horse has some minor arthritic changes, and we just want to make her a little more comfortable, and this was the vet's recomendation. so we'll have to see how she feels in a couple of days!

        TIMEX I would really like to know how the horse responds... I hope she has good luck with it.

          I think that with all joint supplements, you have to experiment a bit--all horses respond a bit differently, and one horse might do best with Adequan while another does best with Legend, etc. My vet started recommending IV polyglycan about a year ago, and fortunately, both of mine have responded fabulously well to it. I honestly feel like they are more comfortable and go longer between hock injections than they did on Adequan. Possibly one of the only times a cheaper solution has ever worked better for my horses :-)

            Small nitpick--polyglycan isn't actually approved as a drug.

            It's considered a medical device because it does not achieve its purpose as a joint lavage through chemical action or by being metabolized by the body.

            In the numerous threads here debating polyglycan/chondroprotec vs. adequan, the results are mixed.

            One vet's experiences:


            • Original Poster

              LEATHER you are correct, technically not a drug when used as a joint lavage. I think either Adequan or Legend works by steric hinderance as well so maybe that is why polyglycan may be useful when administered systemically.


              • #8
                we used polyglycan IV for a couple of years in an event horse who is older and my daughter was competiting CCI* . The horse had no major issues other than age and I really do think the polyglycan made a big difference in terms of over all stiffness. At NAJYRCs last year he was one of only 3 horses who made it around xc and SJ with no faults at all. I know its been used on the tracks for quite a few years with very good results.

                    That article has nothing to do with polyclycan. You cannot substitute polyclycan for chondroprotect in that article just because they are both "devices" that are used off-label in place of adequan.

                    Polyglycan is not a substitute for adequan, they do not work the same. Instead I think people call it an alternative because some horses may respond to one that doesn't respond to the other. Plolyglycan can more reasonably be used as a substitute for legend because polyglycan has HA in it in addition to other ingredients.

                    For my horse with long standing mild arthritis, legend and adequan was not making any difference. Polyglycan makes a huge difference! I give it 2cc for 2 days and then 1cc on the third day. I get a longer response for some reason this way. Given in one dose it was lasting for about a week, this way I get about 3 weeks before it starts fading. I cannot speculate why.

                    My horse no longer gets oral HA, glucosamine, or chondrointon. He does get MSM however.

                      I often use Polyglycan (IV) before horseshows where my horses will be pushed pretty hard. It definitely makes a difference with my mare who was (and is) showing at the top of her scope range. It didn't make much of a difference for my gelding, but then he hasn't had to try terribly hard over the fences we've been doing yet.

                      As others have mentioned, results will vary by horse. It doesn't hurt to try, and it's definitely worth it if it works for your horse.

                        My vet recommended the polyglycan to me recently as well to help treat some hock arthritis in my 20 yr old gelding, in addition to the oral supps he was already receiving. I decided to go the Adequan route first to see if it would help because it was the cheapest option for me. The shots are about $42/each but I can give them myself. Because the polyglycan shots are IV and my vet is particular about who she allows to give IV shots (which is fine because I don't know how to do them!), she or her vet tech would need to come out once a month to give them for me. So even though the polyglycan shots were cheaper for me to purchase, I'd be paying a farm call fee on top of the price of the shot every month.

                        Fortunately, we've finished the loading dose of Adequan and that seems to have brought some relief to my horse. If it hadn't, I would have tried the polyglycan next.

                          well, the vet gave the mare her polyglycan on Saturday, and today was her first day back in work (damn rain!) and she seemed a lot more comfortable. was able to carry herself straighter, didn't try the little hop at the canter like she sometimes will, and just felt a ton better to ride. so we'll see how she goes from here!

                            TIMEX...that's really great news for you and your horse. I hope you continue to see such good results. My mare just got her first injection today and I hope it will keep her comfortable and take care of her joints too.

                            Thanks for the update.

                              I would not use anything that does not have research and results.

                              I think often these supplements run off of placebo effect.

                              I would try Legend before anything else. Then at least you know your $$$ is going towards something that has a chace at working.

                                I use Polyg every 2-3 weeks....

                                on my 20 yr old retired jumper and not only do I think it works, I inject it IM.

                                I also inject his upper & lower hocks & stifles w/ it 2x a year and have had great success.
