No, it's not like that at all. I can cut apart either pair of those shoes and explain the very significant differences to you and why one costs $1000 more than the other.
I have researched this question quite extensively and nobody can give me a detectable, measurable, objective reason why pharma GH might perform better than UGL GH that tests well.
Serum IGF-1 vs. dose is the same. Excipients are similar enough and cheap enough that if that were the difference, UGL vendors would switch. There's mammalian cell derived and E. Coli derived with Serostim being the former, but supposedly mammalian cell derived is *more* difficult to properly purify and offers no benefit. Many non-UGL "generic" pharma producers use E. Coli derived. Genotropin, I believe is one.
The only difference I've been able to identify is "feels". I'm not using the word sarcastically either. The people that report the feels are people that I know and respect.
I wouldn't have any difficulty affording pharma, but I just don't feel compelled to bother. Sourcing it is a hassle and the net benefit of GH is only a fractional part of my program that wouldn't justify 10x the cost of everything else.
If I were a pro, struggling to grow, I might consider it, but I'm not.
I agree psychosomatic effects will always play a big role in "feels". There is a huge difference in terms of pharma vs UGL formulations however.
The excipients used in pharma hgh are far, far more comprehensive than UGL, which is limited to one or two ingredients. This is because preventing aggregation is crucial to minimizing immunogenicity, something UGL (and their customers) don't give a shit about. Aggregation also wastes gh, as it's ineffective in aggregated form.
Reconstitute vials of pharma and UGL, and they may both test as 99% pure, dimer free, but keep them for a week in a refrigerator and the aggregate content of UGL is certainly going. to be far higher.
QSC, probably the biggest seller of UGL HGH, only uses mannitol as an excipient. There is literally nothing to prevent degradation or aggregation. Combine that with crappy BAC water and it's going to go downhill even faster. Those products of degradation are very likely to cause side effects.
Compare that to Norditropin:
histidine, poloxamer 188, phenol, mannitol, HCl/NaOH
Or Genotropin:
dibasic sodium phosphate, glycine, mannitol, metacresol, monobasic sodium phosphate
Here's a list of the major brands and their excipients. They're not including those additional chemicals for no reason:
