RE: Collagen production...
and this piece specifically
Some of the animal studies suggest that short-term low-dose AS administration may increase the collagen fibril diameter and thus strength of new collagen (2930,30). Inhofe et al. demonstrated that a 6-week course of AS (at doses comparable to the typical athleteâ€™s administration) produced a stiffer tendon in exercised rats that failed with less elongation and energy than in control groups (26). The ultrastructural changes in tendon morphology of the AS+exercise subjects varied with an insignificant trend towards larger fibril diameters. These results contrast those reported by other authors (27,28) who observed changes in collagen fibril crimp angle and fibril length.
