Don't give stupid advice as IGF is only good for a week in Bact Water, you need Acetic Acid at 0.6% which i am finding near impossible to source. I am working on getting someone to provide it though.Hopefully they will come through
You could always make it yourself - from vinegar. A lot of people seem to be going that route...Another solution would be if you could source 100mcg vials of IGF and use it at one shot and dillute it with bw.
im not into making it myself i don't trust the sterile(ness) of me making it. Stick to people who know what they are doing At the moment i am going to have to go down the route of buying 2 mgs from Chemone,giving me 4ml of Acetic Acid,use 2 ml on Chemone IGF and keep the other 2 ml of Acetic Acid for innovative research who don't provide solvents but are alot cheaper
