Athletes with high metabolic and muscular stress also show elevation in multi-purpose LFTs such as SGOT, SGPT, and LDH
*Basically all of the above enzymes are found in several other areas in the body, including skeletal muscle. So, to get a more accurate reading Physicians should be particularly sensitive to the discrete liver readings bilirubin, GGT (gamma-glutamyl transferase), and the liver isoenzyme of LDH (lactic dehydrogenase)
Specifically, injectible b-esterfied steroids such as test. are not toxic to the liver (at least it hasn't been proven - and based on the way they are metabolized it doesn't seem likely) while 17-alkylated orals definitely do cause liver toxicity in a dose dependent manner. I've done insane amount of gear and have had normal liver tests, so it really does depend on the person.
2 Studies to Back my statements up:
1) Petera and Lahn found that 30 mg/day of Halotestin administered to subjects found that a peak rise in SGOT and glutamate pyruvate transaminase occurred after 10 days and returned to basal levels after an additional 3 weeks of therapy.
So, it seems that liver test return to normal....
2) No change was observed in 25 patients treated with 25 mg/d of T. Prop injections. Furthermore administration of Andriol (bullshit steroid) also failed to produce elevated liver panel enzymes over 21 days of therapy (Johnsen et. al., 1976).
3) 12 studies were reviewed with a total number of 149 athletes involved (Haupt and Rovere)
LFTs were abnormal in 70 out of the 140 athletes, ALL of which were taking 17-alkylated steroids.
