Veterinary laser therapy is both effective and profitable, but before you purchase a laser for your veterinary practice, we would like to ensure that it’s the right fit for you. Here’s how our 21 day free laser therapy trial works:

1. We ship you the Grady Laser free of charge with marketing, educational materials, and accessories (listed below).

2. Once the laser is in transit, a Grady team member will contact you to set up a training time.

3. You will then have three weeks to use the laser in your clinic.

4. Our team here at Grady is available should you have any questions or should your staff need additional training.

5. At the end of the trial you can choose to purchase the Grady therapy laser (financing is available) or to return it. Should you choose to return the laser, Grady will email you a shipping label so that there is no cost to you.

**Shipment times usually range from 2-4 weeks based on availability**

Current financing is available as low as $250/month. Credit approval is guaranteed for veterinary practices.

Zero cost, zero obligation. Sign up now.

  • After submitting this form, we will contact you to confirm shipping information for your trial laser. Thank you for allowing us the opportunity to help you explore laser therapy for your practice.
The GradyVet P-3000 control unit is compatible with a variety of Class 3b probes to fit your needs.

The effects of all light and laser therapies are primarily photochemical; not thermal – at least, not on a macro-scale – and result from a chain of mechanisms initiated by photon absorption:

  • Primary: Absorption of photons by photo-receptive molecules (e.g. cytochromes, porphyrins, etc.) and the transduction of photon energy to induce chemical changes (i.e., photochemistry)
  • Secondary: Modulation of ATP production (dose dependent), Nitric Oxide release, and the formation of Reactive Oxygen Species (ROS);
  • Tertiary: The products of secondary mechanisms then produce effects such as gene transcription, inter-cellular signaling, and vasodilation; and,
  • Quaternary: Vasodilation increases perfusion, facilitating improved oxygenation and recruitment of macrophages, neutrophils and lymphocytes to areas undergoing repair and/or infection as well as further re-vascularization and proliferation of cells to aid healing. Improved perfusion will also facilitate clearance of inflammatory cells, fluids and debris (i.e. lymphatic drainage) more efficiently.

The bulk of the research to date has been conducted with lasers emitting one watt or less per laser diode – this has been the gold standard and has been proven both safe and effective. At this point, there is not a single peer reviewed article that shows that lasers that exceed one watt to be more effective. In Confounders and Magicians, laser experts Jan Tuner and Lars Hode state the following: ” A certain power is of course necessary, but too much costs just more money and does not give better results…it is easy to make strong laser (we regard lasers with output power exceeding 1 watt as unnecessary strong”
