Sir frag is the one peptide that is supposed to be cloudy. A quick google search wouldve explained this but let me elaborate. ( if there are flakes you just need to roll the vial back and forth for a moment )

The chemical sequence of HGH Fragment is such that it contains very hydrophobic amino acids. Hydrophobic amino acids are very difficult to dissolve. Hydrophobic molecules are literally "water- fearing". A good example of a hydrophobic compound is oil- petroleum. You could see this when BP's oil well spilled millions of gallons of oil into the Gulf. It was not "diluted" by the water. Water is actually an excellent solvent for most peptides.

HGH Fragment is by far the most hydrophobic of any peptides available related to GH research. Now, you have probably purchased HGH Fragment in the past and not had this issue. for reasons I cannot fully explain- this is not an issue with every reconstituted vial. The process in Some manufacturing plants includes using a copious amount of acetonirile. To put this into perspective- when our peptides are being synthesized and then tested for purity- a small amount of acetonirile is used to remove the impurities from a column that is being tested during the HPLC- .1% aceto

Now acetonirile is a poisonous substance and needs to be removed from the final product- (it metabolizes into cyanide). If this substance is not removed, the effects can be very dangerous indeed. Some chemists use 10% acetonirile to dissolve the HGH Fragment! This should not be the case.

So, although this is very counter-intuitive, the fact that your HGH Fragment is cloudy tells you that it is true HGH Fragment, and that it does contain copious amounts of acetonirile.

We know it is not aesthetically pleasing, and again it is hard to wrap our minds around the fact that if something is cloudy that it might not be "bad for us" as compared to something that is not. It is counter to our experiences in life.

Here is the "fix". 1ml of .6% Acetic Acid will completely resolve the situation! The peptides are completely solvent in that mixture.
