What is 100iu of bac water?
The vials contain 10iu of GH each.
You can add any known amount of water that you want and a 10th of that will be 1 iu of HG.
The problem with tiny amounts of water is the loss of HG in the syringe.
If you add 1ml of water (100iu on an insulin syringe) you can inject 40iu on an insulin syringe to get 4iu etc. A 50iu/.5ml syringe might be best for dose measuring.
When adding water to a peptide hormone (GH, IGF-1, HCG etc) never jet the water into the hormone or shake. Inject slowly letting the water run down the side of the vial. Swirl gently to disolve. Draw into the injecting syringe slowly to not shear the peptides and inject slowly as well. Some peptides need to be refrigerated. I don't knpw how recon GH reacts. It does not like heat. But in any case, once mixed, those vials are not going to last long.
Spot injections of GH will do mostly nothing for targeted gains. HG needs to get to the liver to get IGF-1 released.
