CAN gh, SLIN, IGF-1 increase oxygens transport to muscles

[LL08]

I'm trying to remember what improves cardiovascular fitness in terms of 1) speed of oxygen being transported to the muscles and 2) number of mitochondria.

Read in a journal at university somewhere - it is either slin, gf, igf-1 or L3+4

Any help.

Cheers

ive never heard those properties from any of these. slin only in that it activates a cells metabolism so 02 use increases. anadrol increases rbcs some, and epo increases rbcs dramatically.

[LL08]

anadrol - can this be taken orrally? Cycled with gh slin, and var?
