How to test whether growth hormone is real or fake?
Bacterial residue in low grade Somatropin or Somatrem
"Painful red welts on injection spot can be caused by low quality growth hormone which contain too much bacterial residue. This can lead to serious problems where the body could eventually develop resistance even against its own naturally produced growth hormone.
The 192 amino acid sequence growth hormone is called somatrem while the real 191 amino acid sequence is somatropin. Somatrem is easier and much cheaper to produce. Only a proper lab analysis can show if the substance is 191 or 192 amino acid sequence.
Occasional painful welt does not automatically mean that the substance is somatrem. From time to time it can happen with somatropin too (if you hit an awkward spot). If the welts appear after every injection and persist for a day or two, then you should discontinue the cycle immediately and have a sample lab tested.
Beware of HGH supplements, sprays, pills or patches. Those are just marketing scams and do not contain any real growth hormone. See "hgh sprays, pills and patches" page for more info."
