In my opinion I wouldn' deal with a lyphosized IGF-1 sourec if he wasn' t suppling the ACETIC ACID for mixing and 0.9% SODIUM CHLORIDE for injecting.
Put 1ml ACETIC ACID in the vile and that will last you 20 days if you draw up 5iu (5 ticks) mark on a insulin pin. Thats 50mcg IGF-1 per 5iu injection on a slin pin.
After you draw up 5iu igf-1 solution mixed with ACETIC ACID you draw up some 0.9% SODIUM CHLORIDE to dilute the igf-1 solution and inject. Make sure you dont inject your igf-1 soluion into the 0.9% SODIUM CHLORIDE bottle when drawing it up by drawing back on the pin and craeting a little space before doing so.
