I've still never tried AA.
Until recently the cost was similar to injectable PGF2a, wich I never had much success with. Recently I've read that the PGE (the inflamatory one) is nearly as important for muscle growth associated w/ AA as the PGF2a. Wich would explain why PGF2a alone didnt do much. But since AA increases production of both, people seem to be having decent results from it.
Yes, very true. PGF2a is just a small part of the equation. Xfactor works through a number of mechanisms:
- Increasing the density of androgen receptors/local T sensitivity (PG's)
- Upregulating local insulin sensitivity (PGE2)
- Upregulating local NO production, which aids satellite cell activation via increasing levels of Hepatocyte growth factor (PGE2)
- Upregulating local IGF-1 receptor expression (PGF2a)
- Upregulating expression or sensitivity to other growth factors like TNF, FGF, IL's, (various)
- Modulation of PPAR and cAMP providing powerful fat loss and total body recomp properties
