Singhbuilder, Its difficult to make conclusions from the limited information given about the study. It doesnt specify what “anabolic steroids” were used so its possible GH/IGF-1 was included as well.
Also I thought it may just be that the differences in musculature were due to performing at a high level regardless of whether AAS was used to get there or not.
To quote the findings section of the article: ‘The researchers found that several years after anabolic steroid withdrawal, and with no or low current strength-training, the muscle fiber area intensity, the number of nuclei per fiber in the quadriceps was still comparable to that of athletes that were currently performing high intensity strength-training.’
Doesn’t this just mean that the old users were comparable to current tranees who don’t use? Its possible that the permanent changes are a result of the actual training and not the AAS.
Again: ‘They also discovered that the shoulder-neck fiber areas were comparable to high-intensity trained athletes and the number of nuclei per fiber was even higher than found in the current steroid-using group.’
The last part interests me because the old users had higher nuclei per fibre than current users. Possibly because the current users, while using AAS, have not yet reached a level equal to the old users in terms of performance/muscle maturity.
Just throwing ideas around.
