Trenbolone acetate and Estradiol Implant
Trenbolone acetate 200 mg and Estradiol 20 mg
VETERINARY USE ONLY
FOR FEEDLOT STEERS AND HEIFERS
Revalor®-XR is an implant containing 200 mg of trenbolone acetate and 20 mg estradiol. Each implant consists of 10 small yellow pellets coated with a polymer for delayed and extended release.
Each pellet contains:
20 mg trenbolone acetate and 2 mg estradiol.
Non-Medicinal Ingredients: 4.25 mg cholesterol, 0.5 mg magnesium stearate, 0.25 mg ethylcellulose N200, 1.69 mg poly-(DL-lactide-co-glycolide) 65:35, 0.08 mg colloidal silica anhydrous.
To increase rate of weight gain and improve feed efficiency during 70-200 days after implantation in feedlot steers and heifers.
Efficacy was confirmed in growth promotion trials conducted in steers weighing 230 - 327 kg and heifers weighing 230 - 308 kg at the time of implantation.
Revalor-XR Dosage And Administration
One implant containing 200 mg trenbolone acetate and 20 mg estradiol is administered to each animal. The 10 pellets which make up the dosage of Revalor®-XR are contained in one division of the multiple dose cartridge. Each cartridge contains 10 doses. The cartridge is designed to be used with the Revalor® implant gun.
a) Site of Administration:
The implant is placed under the skin on the posterior aspect of the ear by means of the Revalor® implanter available from Intervet Canada Corp. After properly restraining the animal to allow access to the ear, cleanse the skin at the implant needle puncture site. Improperly cleansed skin may result in abscess formation and the subsequent loss of the implant. The implant is placed subcutaneously between the skin and cartilage on the back, middle third of the ear below the midline (see Figure 1). The implant must not be placed closer to the head than the outer edge of the cartilage ring. The location of needle insertion is at a point corresponding to the centre of the ear with the needle directed towards the head, and at least a needle length away from the intended deposition site (see Figure 2). Care should be taken to avoid injuring the major blood vessels or cartilage of the ear.

b) Method of Administration:
1. Do not remove the cap (C) of the cartridge containing the implants.
2. Place the cartridge (D) (with the capped end to the front) into slot at the top of the implanter magazine (labelled A on the diagram).
3. Gently push the cartridge into the slot until it clicks into place.
4. The implanter is now ready for use.
5. Take the ear of the animal firmly with the free hand (in the manner shown in Figure 1) and insert the needle into the subcutaneous tissue at the point indicated (Figure 2). Press the trigger (E on Figure 3).
6. The retraction bar will automatically withdraw the needle from the ear aiding in depositing the pellets of the implant in a single row.
7. The gun automatically advances the cartridge to the next implant.
8. When all the implants have been administered, the cartridge will fall out of the bottom of the magazine and may be replaced by a new one.
9. To change the needle, loosen the needle locking nut (labelled F in Figure 3) and replace the needle. Tighten the nut finger tight and the implanter is ready for use.
