This is actually an inaccurate but quite common misconception. People assume this to be the case because most middle men are no better than another. A key indictator of whether or not your source is an actual manufacturer is the extent of his list, ability to synthesize an uncommon product that you need, purity of his products, lower cost of said products.
Another very recent but extremely important aspect that everyone still overlooks to this day: a legitimate manufacturer will not be manufacturing/selling hgh.
This changed this year. It is illegal for us to do so. We will be imprisoned if caught. Whereas the manufacture of AAS and Peptides-HGH not included-is still 100% legal.
