Lypholized form must be better for transport as liquid degrades the hormone especially when you don't know at what temperature it's being moved. if anyone is offering you pre-mixed then there is 2 things to consider:
1)how long will be shipping
2)what temperature is outside, if it's hot summer then forget it your vial will arrive degraded, depends on products some peptides degrade really quick even in fridge.
IGF-1 LR3 is expensive enough to not play around with it. Order it in powder form, add water at home and keep in fridge. period. <- if you want get most out of what you paid.
Acetic Acid is what i use, but i can't really tell why, i just read it's what you have to use with your igf1
It has something to do with PH levels in water and what makes peptides last longer, bacteriostatic water is just water with some antibactererial properties added, not best for fast degrade peptides.
Apart from melanotan i use all my peptides within 1 week of reconstitution and i use regular sterile water. For some reason i am not comfortable with Acetic acid injections and no source for bacteriostatic one.
Finish IGF-1Lr3 is freeze-dried powder, Use sterile water or bacteriostatic water to dissolve it. Not open can be saved for a long time at low temperature.
