Trenbolone Hexahydrobenzylcarbonate is a derivative of nandrolone, so you can compare it with this drug, but only by the molecule structure and nothing else. Trenbolone is hands down the strongest steroid available for purchase today. There are no other compounds that work like trenbolone. Most other AAS do not come close to the strength trenbolone has. This is what make it so popular in the bodybuilding and fitness industries. Nandrolone is by far inferior to trenbolone in a number of parameters. It is aromatized and not suitable for building lean muscle mass if used solo in cycle. To improve the quality of the muscles in a cycle with nandrolone users will stack trenbolone to it for far greater results than just nandrolone.
Also, this steroid can be compared to the classic - testosterone. It is believed that in a bundle of testosterone with a tren first should be 3 times more, but this is just a myth. It is important not to exceed the dosage of simulator above 300 mg in combination and not to overestimate the dosage of testosterone.
As for comparison, testosterone is inferior to trenbolone: it has less androgenic and anabolic activity, it is aromatized, does not lead to a sharp increase in weight. In fact, testosterone mimics the endogenous sex hormone, so the muscle mass in standard dosages, it increases slightly.
Trenbolone Hexahydrobenzylcarbonate is another matter entirely. It has a powerful effect and allows you to seriously gain weight and increase power performance. If the athlete competently uses softer steroids on the "bridge" between courses, then 70-80% of the mass can be saved.
