Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In orchiectomized adult rats, both testosterone and trenbolone elevated expression of the anabolic gene for mechano-growth factor in LABC muscle.

    In plain wordsIn rats, testosterone and trenbolone each raised the body's own MGF gene activity in a muscle.

    Summary
    Both androgens elevated expression of anabolic genes (insulin-like growth factor-1 and mechano-growth factor) after ORX.
    1 context sentence
    Summary · context
    We now report differential gene expression in response to testosterone versus trenbolone in the highly androgen-sensitive levator ani/bulbocavernosus (LABC) muscle complex of the adult rat after 6weeks of orchiectomy (ORX), using real time PCR.

    This result measures the body's own MGF / PEG-MGF. Nobody was given the peptide. It is not evidence about taking it.
