Now that we have a frame of reference regarding potency per mg, we can move onto what really matters, which is how these steroids stack up against each other in terms of muscle-building potency per “effective dose”. It is a steroid’s effective dose which determines how much muscle it can potentially build in comparison to another steroid. It doesn’t matter how strong a steroid is per mg if it is so toxic that we can only use it in mcg quantities. There are plenty of steroids out there which demonstrate an anabolic capacity, per mg, which is many times greater than any other steroid ever produced by either a pharmaceutical or supplement company. But… but many of them are so toxic that they cannot be administered in dosages anywhere close to those used with the steroids listed above. We see this occurrence with a steroid like Cheque drops. It is exceedingly potent, yet every bit as toxic, which effectively prevents the drug from being dosed high enough to build any meaningful degree of muscle mass. This is why a drug’s “effective dose” is so vital in determining its true muscle-building potential in the real-world.
