Popular HGH Pen & Injection Brands
HGH pens combine recombinant human growth hormone with a dedicated delivery system. Compare the brands buyers search most often, their format, manufacturer and published price references.
A pen is a delivery format, not a different hormone. Pharmaceutical HGH pens contain somatropin, recombinant human growth hormone with the same 191-amino-acid sequence as endogenous HGH. Differences between brands are typically in concentration, device design, preparation, storage, manufacturer and price.
