OK, to answer my own question above about LGD boosting testosterone and to maybe provide others with facts, I found published research from S Basaria at Journals of Gerontology, Series A, 2013 Jan; 68, 87-95 which among other things stated:
[FONT="]"LGD-4033 administration was associated with dose-dependent suppression of total testosterone, sex hormone–binding globulin, high density lipoprotein cholesterol, and triglyceride levels. follicle-stimulating hormone and free testosterone showed significant suppression at 1.0-mg dose only. Lean body mass increased dose dependently, but fat mass did not change significantly. Hormone levels and lipids returned to baseline after treatment discontinuation."
I have seen so many claims from sellers of this product that it boosts testosterone, which is totally the opposite so caveat emptor.[/FONT]
