Protein purity and dimer content.
Those are the things that matter and those that I test for.

The higher the purity, the better, the lower the dimer, the better.

I think it was described in these articles:
Analysis of recombinant human growth hormone and its related impurities by capillary electrophoresis
Study of dimer and oligomers of human growth hormone

but I'm not 100% sure it was these and I don't have the time to go through them now

I might elaborate tomorrow or day after, but I'm in agony due to surgery and will be laying down now.

Damn bro you're on a whole other level with this. Thanks for getting this info out there I need to step my game up on the research
 
Are you guys keeping the unmixed bottles in the fridge also? I know once mixed it has to be in the fridge

I do just easier to keep it all together. Unmixed doesn't need to be refrigerated but does need to keep away from direct sunlight n extreme high temps so fridge solves both issues.

Excuse my ignorance but what exactly is dimer?

Simply put, it's two molecules of HGH joined together with a weak ('non-chemical') bond.
It can be used as a marker of production/storage quality and effectiveness of the HGH. (the lower the better).


The above applies only to HGH - it gets complicated after that. For example you can have homodimer (two same molecules co-joined - like in HGH) or heterodimer (two different molecules cojoined (like in reverse transcriptase). There are even dimers, which are chemically bonded - usually with disulphide bridges, although other bonds are possible as well.

I appreciate what you contribute to the board. Posts like this help me and others who are researching in the long run. I know it can be frustrating sometimes for guys who have extensive knowledge to answer what may seem basic to them, but everyone benefits when the information is out there.

Thank you!

Au contraire.
It is absolutely not frustrating to explain anything to people eager to learn.
I find it very energizing to share the knowledge and help people where I can.

I don't expect people to know details of protein chemistry and analytics - that would be unreasonable to expect of anybody whose job doesn't concern that.
