heck idk man, im no GH guru.
i hope i didnt chunk 2 kits for nothing. it looked exactly like the OP's pic.
i tried half a ml, 1ml, 2ml. didnt matter it turned cloudy.
this was from a guaranteed sponsor(everything has been great with this sponsor, and didnt expect them to send me more gh after 2 years)
and the vials were kept in a cabinet at 68-75 degrees the entire time.(did not keep it in the fridge)
it was crystal clear when i first got it, then stopped gh, came back to it a year or 2 later and it was cloudy upon reconstitution.
i always do the "dribble" method, never squirt the Bac stat harshly into the vial.
before this happened i figured gh would be shelf stable in lyophilized powder for a few years.
if i remember correctly i read about the proteins becoming unfolded or denatured due to temp changes, solvents, harsh recon methods etc.
but still it was sitting in a cabinet in the AC for about 2 years.
im interested to hear to what others have to say on this. ive read on here some didnt care, shot the cloudy gh and all was fine, others say its not as potent or is useless.
