Regarding the 94% HGH purity requirement for HGH:
This is well known and causes a common misconception that UGL HGH is just as good as pharma HGH because the purity of UGL HGH is oftentimes higher than pharma.
Pharma HGH has excipients added to help buffer PH, which helps mitigate protein degradation, reducing aggregates and thereby immunogenicity. I haven't heard of any UGL vendors mention that they're adding excipients to keep HGH at the ideal PH levels. A move away from ideal PH will greatly impact degradation.
IMO this is why people will report experiencing less "dirty" side effects using pharma HGH compared to UGL HGH.
The other big difference is that pharmaceutical companies are required to explain the exact contents of the remaining 6% and why they can't be removed. UGL def aint doing that lol.
