Everything you need comes in the Home Med Kit. Work out the exact dose with our free calculator, then confirm the plan with your vet before you start.
1Wipe the bacteriostatic water vial with an alcohol swab. Draw the exact amount of water your mix calls for into the syringe. Our calculator gives you the number for your vial size.
2Release the water slowly down the inside wall of the peptide vial, not onto the powder. Let it dissolve, or swirl gently. Never shake. It is ready when the liquid runs completely clear.
3Draw the mixed peptide back up, then transfer it into the pen's glass cartridge. Screw the pen back together and twist a fresh needle onto the tip.
4Hold the pen needle up and tap so any air floats to the top. Dial 2 units and press until a small drop appears at the tip. This clears the air so your dose is accurate.
5Turn the dial to the exact number of units from the calculator. It shows in the window. Double check it before you go anywhere near your pet.
6Pinch a fold of loose skin at the scruff or flank, slide the needle in at 45 to 90 degrees, press the plunger all the way and hold a few seconds. Withdraw, and rotate the spot each time.
For subcutaneous use in animals under veterinary guidance. Start at the safe minimum dose, keep everything clean, and use a fresh needle each time.
TB-500 is the deep-repair partner for the harder cases: the old cruciate, the tendon that keeps re-tearing, the working dog that never quite comes right. It is dosed on a simple weekly rhythm rather than daily, which makes it easy to keep on top of alongside BPC-157.
