Hgh in pill form will be broken down before it reaches systemic circulation. Remember that hgh is a relatively large peptide of 191 amino acids. If will therefore be digested in somewhat the same way as proteins in your food. And when the hgh is split by a stomach enzyme just once into two fragments, it's very likely it won't work anymore.
So don't waste money on hgh in pill form. If you're gonna go that route use peptides that work as hgh releasers, but they to need to be injected. No peptide will work orally in any meaningful way for this purpose IMO.
