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. These rules may be amended at any time to address the current needs of the board.

  • Adequan VS Legend

    What are your thoughts on Adequan and Legend.

    Which one do you use and why do you thinks is better than the other???

  • #2
    My horse responded better with the Legend because he has horrible joint fluid so this is HA and worked really well for him.

    I wish I could afford both because they are both really great products.

      In my experience it really depends on the horse. My late TB did dramatically better on Legend, but I've had others where the opposite was true. Try 'em, one at a time, and pick whichever helps your horse more.

          From an article I wrote years ago:

          Sodium hyaluronate has been investigated as a therapeutic since 1970. It is primarily effective in treating synovitis (inflammation of the synovial membrane). Although the exact function of sodium hyaluronate is still being elucidated, evidence suggests that it acts to help “normalize” the environment around the synovial membrane. This may be accomplished in several methods. Sodium hyaluronate may help scavenge the radical oxygen present during the inflammatory response thus acting as a mild anti-inflammatory agent. It may also prevent access of inflammatory enzymes to the cartilage by simply “taking up space”. It has also been suggested that sodium hyaluronate helps stabilize the viscosity of synovial fluid aiding in joint lubrication, although this role of sodium hyaluronate in joint lubrication is still subject to debate.

          Polysulfated glycosaminoglycans act to inhibit the destructive enzymes associated with the breakdown of articular cartilage. In a sense it acts as a decoy by binding to the articular cartilage surface and sacrificing itself to spare the proteoglycans in the hyaline cartilage. In addition it may stimulate hyaluronic acid synthesis.

          To summarize these two types of drugs, sodium hyaluronate is primarily an anti-inflammatory that may help stabilize the environment in and around the synovium along with stabilizing the viscosity of the synovial fluid. Adequan protects the articular cartilage (chondroprotective) from the destructive enzymes released in joint inflammation. In both instances neither drug has been shown to reverse damage incurred by hyaline cartilage. That leads us to the next generation of drugs that, in conjunction with anti-inflammatory treatments has been shown to regrow the articular surface, reversing the effects of DJD.

            Does anyone know what joints both Adequan & Legend have the greatest effect on? I had the articles saved but can't find them at the moment...


            • #7
              I used Adequan on my horses in the past and this year I am using it for my dog. My dog is young and had a leg that was broken and never set. Consequently she has arthritis in both the knee and shoulder. I started her on Canine Adequan and, contrary to a post above, my vet said it would lubricate as well as rebuild. Whatever it does it works and she will get it for the rest of her life.

              "Adequan is an injectable substance known as a "polysulfated glycosaminoglycan," and is very similar to the more familiar oral supplement known as glucosamine. Adequan has been proven to be preferentially taken up by inflamed joints when injected into the dog's muscles. It soothes and lubricates the joint, naturally reducing inflammation and pain by reducing friction. Even better, instead of just masking pain as NSAIDs do, it actually helps to rebuild cartilage in the damaged joint. It's not just pain control, it's therapy."

                This is off the Legend Website:

                CLINICAL STUDIES:
                Forty-six horses with lameness in either the carpal or fetlock joints were treated intravenously or intro-articularly with Legend Injectable Solution in a well controlled clinical field trial conducted at four locations. One, two or three injections were given based on clinical improvement.
                Overall clinical improvement was judged as excellent or good in 90% of the cases treated intravenously and 96% of those treated intra-articularly with Legend Injectable Solution.

                  LeeB, what is the source of your quote about Adequan?

                  Anecdotally, I had a horse who had been "worn out" by his previous owners. You couldn't tell which leg was lame because when you blocked out one, another went off. Legend was an absolute miracle worker for this horse... it was like 5 years of hard work had just been taken off his body.


                  • #10
                    Found several pages that say Adequan helps to rebuild cartiledge:

                    Adequan works to fight and stop any injurious activity that may commence as a result of the inflammation. It also immobilizes the enzymes and the free radicals responsible for destroying the joint's fluids and tissues. As a complimentary function, Adequan Equine stimulates the synthesis of cartilage building compounds and stops the production of chemicals that cause pain. As such the joint function of the horse acquires improved efficiency. Adequan therefore stands out as the only product in the market that serves the functions of relieving pain while stimulating cartilage repair action.

                      Synovial joints (joints that contain synovial membrane and fluid). That means it does not help the lower joints in the hock and knee but does help the upper high motion joints (e..g tarsocural).


                      • #12

                        No, what you see is clever marketing. Adequan has never been shown to rebuild hyaline cartilage. It has been shown to diminish the degradation of hyaline cartilage and to maintain joint spaces. Yes, in cell and tissue culture it has been shown to increase compound synthesis but that does not mimic the living mechanically loaded environment. It can not be directly related back to what happens to joints in a clinic.

                        There is no recent study (last 10 years) that specifically states or shows that Adequan builds or creates hyaline cartilage in dogs or horses.

                          Reed - any info on this next gen of drugs that reverse DJD?

                            That is sadly the $64 question. There are therapies that will regrow hyaline cartilage (but they are a tad expensive at around $5000 per treatment). HOWEVER, most drug companies are not following up on this. Why? It is not financially beneficial to the company. I know of 2 specific instances where a drug company killed positive trials because the accountants decided the return on investment was too low.

                            Suffice to say, drugs and molecules such as IGF-1, and -2, IGFbp-1 through 5 and pentosan polysulfate have regrown cartilage when used synergistically. The key was managing the joint environment.

                            Joints are insanely complex at the biological level and we are still just figuring out how a fraction of that biology works.

                              Thanks for the info! Appreciate all the detail and you taking the time to educate.

                              I'm having better results from pentosan than the compounded acetyl glucosamine.

                                  Many of our hardest working or horses vet thinks need it get a 7 series pack 1 or 2 times a year and monthly shots after. All the harder working or older horses get Legend every month or at the show that month.

                                  For us it is not a either or it is BOTH


                                  They also sell a multi dose bottle

                                    I would be VERY concerned if you were giving this amount to any horse. These molecules are heparin-like and can also cause thinning of the blood vessel walls etc. when given at high dosages. There is evidence that the sudden deaths of horses from "aortic rupture" can be brought about by excessive administration of drugs such as Legend, Adequan, MAP-5, or any other PSGAG.

                                    I have a personal case as well that may have bleed out due to administration of multiple doses of Adequan and Legend every 2 weeks.

                                    More does NOT mean better. Sometimes, a horse is done and needs to be retired.

                                      I think I may not have been clear

                                      A horse may get a 7 series dose of Adq which is every 4-5 days one time a year (we had 2 older horses who will get the series in spring and fall) and when series is over 1 adq a month and one legend a month. We try and have the legend fall at the shows which for many of the event horses is one time per month.

                                      NOT seeing where that is a gross level of the product. Sorry if the amounts above were not clear in original posting

                                      To be more clear

                                      Lets say BOB the horse will start on a 7 series pack in Jan and then march through dec he receives 1 adq per month and one legend per month.. Pretty standard actually.

                                      ADEQUAN® I.M. Rx Luitpold Brand of Polysulfated Glycosaminoglycan (PSGAG) Solution 500 mg/5 mL For Intramuscular Use In Horses

                                      TOXICITY Toxicity studies were conducted in horses. Doses as high as 2,500 mg were administered intramuscularly to 6 horses twice a week for 12 weeks. This dosage is 5 times the recommended dosage and 3 times the recommended therapeutic regimen. Clinical observations revealed no o reness or swelling at the injection site or in the affected joint. No animal had any clinical or laboratory evidence of toxicity.

                                      DOSAGE AND ADMINISTRATION The recommended dose of Adequan® i.m. in horses is 500 mg every 4 days for 28 days intramuscularly. The injection site must be thoroughly cleansed prior to injection. Do not mix Adequan® i.m. with other drugs or solvents.

                                        Reed, are you saying that the data does not support a regular program of biweekly or monthly adequan or legend given the other risks? Or that you wouldn't repeat the loading dose of adequan yearly? And does the same concerns extend to polyglycan?
