More satelite cells does mean more receptors, so Testosterone alone results in new receptors. I am not downplaying the effects of hgh but pointing out that testosterone administration of 300mg per week will result in more satelite cells and that this relationship is dose dependant as the study I provided states. In other words the more Testosterone administered the more satellite cells increase. The study demonstrated this dose dependancy up to 600mg per week but did not use higher doses for ethical reasons.
