What's the interaction between hgh and humatrope (human growth hormone)?

HGH: Hgh stands for human growth hormone, not because it comes from humans, but because growth hormone is species specific, meaning human growth hormone will not have effects on for example horses or cows. Humatrope is one of the synthetic forms available of human growth hormone produced by lilly pharmaceutical.

Same basically: Humatrope (human growth hormone) is synthetically derived, but bio identical to hgh.
