The terms and conditions of the contract apply equally to the supply of both products and services except where application to one or the other is specified. While Clenbuterol and Albuterol can be used as short-term treatments for asthma, they are better known as performance-enhancing drugs, predominantly used in body-building and weight-loss programmes to simultaneously reduce body fat and increase muscle mass. Authorisation for the return of products which fail to meet current published manufacturer’s specifications must be requested in writing within 28 days of delivery. VWR will assist customers, at customers’ expense, to obtain any manufacturer’s warranty consistent with that granted to VWR. VWR shall deliver to the address set out in the order (delivery location) at any time after it gives notification that the products are ready for delivery. Delivery is completed when the products are unloaded at the delivery location (or immediately before if the customer is responsible for unloading in accordance with this contract).
Clenbuterol marketed as Spiropent, Ventipulmin, and also generically as clenbuterol, is a sympathomimetic amine used by sufferers of breathing disorders as a decongestant and bronchodilator. Nobody has ever claimed there was a link between this case and the Contador one. The German Sport University Cologne(ironically the lab that tested Contador’s https://www.tekshop.pt/new-study-reveals-positive-effects-of-cabergoline/ samples from last year’s Tour de France) tested 28 travellers returning from China over a four month period from 15th September last year to the 15th of January this year. 22 of the 28 tested positive for low levels of clenbuterol in their blood streams leading the lab to warn athletes of the dangers of eating meat while in China.
Property Highlights
There has also been evidence that meat contaminated with the drug is being produced and sold on the global market, despite it being banned from the human food chain in both the USA and the EU. During the recent horsemeat scandal in Europe, several products labeled as beef were found to contain horsemeat from animals treated with the drug. There were also instances in China where Clenbuterol-tainted pork caused hundreds of people to become sick4. However, it is now possible to make use of highly sensitive liquid chromatography mass spectrometry (LC-MS) for the unequivocal identification and quantification of Clenbuterol in equine plasma. Unlike urine samples, results from plasma do not oscillate between positive and negative11.

- We found alternative products that can save you up to per item-unit.
- Clenbuterol can be used to promote lean muscle growth in livestock but the resulting meat can be tainted with the drug.
- Another rider sure to be taking a keen interest is the Dane Philip Nielsen who failed a test for Clenbuterol at the Tour of Mexico last year – another country known to have a problem with illegal use of the drug by livestock farmers.
In recent years, the trend has been towards more strict regulation. Two years ago, the American Quarter Horse Association (AQHA) officially advanced a proposal for a 30 day withdrawal of Clenbuterol prior to a horse competing in a race, and established threshold levels of 200pg/ml or less in urine and 1-2pg/ml in blood6. Increased withdrawal periods were subsequently adopted by associations in several states, including New Mexico, California and Oklahoma7.

If we receive a prescription that is invalid, forged or altered, we will immediately cancel the whole order, de-activate the user account, report the misuse to the Veterinary Medicine Directorate and charge a reporting fee of £50. Remember to ask your vet for a repeat prescription if your animal is on long term medication – it will save you time and money. Premium next day delivery is also available for this item but we must receive the order and prescription by 12 noon. This item is a prescription medication and cannot be sent until a valid prescription is received. Please note, we only accept prescriptions written by vets registered in the UK with the Royal College of Veterinary Surgeons.
VWR shall provide services to the customer in accordance with the specification agreed between them from time to time. Such services will be provided with all reasonable care and skill. Where delivery or performance dates are stated by VWR these are estimates only and time is not of the essence; however, if VWR needs to change such dates it will do so only after providing information to the customer and having regards to the customer’s stated objectives. VWR has the right to change the prices shown in catalogues and price lists at any time and to invoice at prices current at the date of receipt of an order.
Testing serum also allows the immediate detection of Clenbuterol administered by the intra-tracheal route or nebulization, which would be the likely strategy for any pre-race doping12. Precise LC-MS quantification can distinguish between residual traces from treatment and administrations designed to enhance short-term performance, particularly as there is good correlation between concentrations of Clenbuterol in serum and its pharmacological effects13. This allows regulators to set a lower withdrawal period, while maintaining complete confidence that no pharmacologically significant residue of the medication will be present in the horse during a race. Clenbuterol is a sympathomimetic amine (beta-2 agonist) used in the treatment of breathing disorders, as it relaxes the smooth muscles in the airways acting as a bronchodilator. A common side effect is due to its thermogenic properties, which increase basal metabolism rates, blood pressure, and oxygen transport helping build muscle mass, while reducing body-fat. These combined properties – characteristic of a beta-2 agonist with thermogenic side-effects – resulted in Clenbuterol being labeled as a banned substance in Olympic athletes and for animals used for human consumption.
Any liability accepted by VWR under this contract is in lieu of any terms implied by law as to the quality or fitness for any particular purpose of the products and/or the standard of the services and all such implied terms are, to the fullest extent permitted by law, excluded from the contract between VWR and the customer. The customer shall indemnify VWR against any claims made against VWR by the customer’s employees, contractors or agents. Risk in products will pass at the time of delivery to the customer. The customer is responsible for unloading and transporting large and/or heavy items from delivery vans and for supervising the unloading of all other products delivered. VWR’s products can be hazardous and all customers are required to comply with the VWR account application procedures which are available on request. VWR reserves the right immediately to cancel any orders from customers who have not complied in full with these procedures.
Clenbuterol (hydrochloride)
Tension generation and relaxation following sudden increase and decrease in [Ca(2+)] were much faster in the R403Q myofibrils with relaxation rates being the most affected parameters. The results show that the R403Q mutation leads to an apparent gain of protein function but a greater energetic cost of tension generation. Increased energy cost of tension generation may be central to the FHC disease process, help explain some unresolved clinical observations, and carry significant therapeutic implications. Eating meat contaminated with clenbuterol can lead to a positive blood test. So says a study conducted by a WADA accredited lab in Germany and released this week, findings that go some way to backing up Alberto Contador’s claim to have accidentally ingested clenbuterol when he ate a contaminated steak at last year’s Tour de France.
The Clenbuterol ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of clenbuterol and other related ß-agonists in feed, meat/liver/kidney, milk and urine. ELISA can be used as a screening system, which is simple, rapid, sensitive and cost-effective compared with traditional methods such as HPLC or GC-MS. We send all our prescription medication by a tracked courier service and dispatch only occurs on a Monday to Thursday. Clenbuterol is a pharmaceutical decongestant and bronchodilator prescribed to treat asthma with illicit uses as a performance-enhancing drug. This Snap-N-Spike® Reference Solution is suitable for use as starting material in calibrators or controls for a variety of LC/MS or GC/MS applications from forensic analysis and urine drug testing and to clinical toxicology and sports testing.
