Do bodybuilders need to avoid using any specific steroids?

Good Question!
Nobody asks this usually.
This steroid, known as Trenbolone Acetate, should be avoided if you are not a fitness model or professional bodybuilder because it is a powerful steroid that affects the health of organs. The liver and Kidneys are being affected by it, and hormonal imbalance is also observed in some cases. Instead of trenbolone acetate, use Primobolan with Masteron. It gives the same results with fewer drawbacks; also, it's low cost.

Metribolone and Halotestin, because it doesn't add any tissue and in my opinion it's too toxic to human body as well.

Steroids are normally categorised as prohibited substances because of the possibility of overuse and negative consequences on health. But unfortunately, a professional bodybuilder cannot compete successfully without taking steroids. The human body also needs a physical workout along with the steroid so don't forget that!
The amount of steroids should be limited and according to the prescription, once you start getting addicted to it, the game is over for you! This can be lethal.

Yes, brother. There are many anabolic steroids that are too toxic or don’t really add any tissue. A few examples are metribolone or Halotestin. Another one would be cheque drops.

No steroids and I'm glad I don't use them. I have health problems at an early age as a result of steroid addiction. I would suggest you to not addict your body on steroids and take proper guidance and consultation from doctor or professional.

As far as my experience speaks, there is no need to take trenbolone acetate unless you intend to compete or are a fitness model. It works, and perhaps that's the problem: it's horrible on your liver and kidneys, messes up your hormonal balance, and your thinking is never the same even months afterward. Using Primobolan in conjunction with Masteron will produce a comparable result at a considerably lower cost.
