I've found this:

If our muscles were created out of such maleable fibers that an intense pump from a few sets of bicep curls over the course of a few months could actually expand the muscle fascia beyond its genetic potential then 75 percent of young males would have 18+ inch arms. Unfortunately, most people lack the insight to sit down and realize that something else must be going on for this training protocol to work - so instead they apply it to their own natural protocol, see zero results but thanks to the placebo effect and cognitive dissonance, trick themselves into thinking its working and spread the word to other natural beginner lifters - and the cycle repeats.
Here is the truth about FST-7.
Yes, the protocol calls for about 7 high rep pump sets isolating a muscle group at the end of the workout. But there is a lot more to it. The key to the FST-7 protocol of expanding the muscle fascia involves regular site injections of a mixture of site enhancement oils and anabolics, injected into the specific muscle - usually a relatively high cc quantity. This is the primary mechanism of what actually causes the stretching of the muscle fascia - the high rep pump sets to induce blood volume are for site specific nutrient shuttling and secondarily, to increase long term expansion already induced by the large quantity of oil.
Furthermore, another key component ot FST-7 is localized IGF-1 injections as well as very high dose insulin usage immediately after the muscle has been completely engorged.
The FST-7 protocol works, but only for advanced drug users. If you are natural, or just on anabolics it wont do anything at all.
Is this real?
