Great build.
Didn't even know the first synthetic GH was incomplete, or whatever, and could cause issues. That's mental
Lots of peptides are modified for various reason, maybe stability, maybe length of action and so on. Many of the popular insulins aren't the exact same as human insulins. With IGF-1 they put the "LR3" that greatly extended active life, to like 24 hours as opposed to minutes. With Protropin the potential for antibodies was there but the companies data said it wasn't a concern. China made the version "Ansomone" and many thought it was great. Then they also split out only a portion of thr growth hormone for specific effects, for fat loss.
"The HGH fragment (176-191) is a synthetic peptide that represents a specific short portion of the amino acid chain found in HGH. This fragment corresponds to amino acids located at positions 176-191 at the C-terminus of the human growth hormone. While only a fraction of the full HGH molecule, this fragment is responsible for its potent fat burning properties without significantly affecting insulin levels"
This has been sold for years and some still like it.
