Claiming to be a growth complex and a revolutionary breakthrough in HGH technology, HeightFX uses 4 more complexes they claim will help you to feel younger, encourage HGH, and otherwise help yourself. In short, they use proprietary blends to hide ingredients you can already see aren’t worth anything. It uses l-dopa, grape seed extract, urtica dioca, huperzia serrata extract, cordyceps sinesis extract, eurycoma longifolia extract, and epimedium brevicornum extract, which have nothing to do with HGH. This is probably why there is not a single site actually selling this product. We would not suggest buying it should it reappear.
