Trenbolone acetate is a potent androgenic steroid. It is a potent androgen, which will not readily convert to estrogen. Since in this case it is in the form of a cattle implant, administration is a bit difficult. Either when applied to the skin, or injected, users report great strength and mass gains with no gyno or water retention. Along with being a strong muscle-building steroid, it is also noted as being very effective at burning fat.
This has made it very appealing for competitive athletes looking to shed fat, while at the same time trying to avoid water retention and keep the hard physique, which a strong androgen helps bring about. It should be noted that this is not a beginner's steroid. Trenbolone can be very toxic, especially to the kidneys. Since this is a strong androgen, related side effects such as acne and increased aggression are also very common. To be cautious, users will commonly limit their use of this drug to 4 or 6 weeks. Average dosage is 80-100 mg per day for men.
