Only kidding about the crabs Bro! Try this, take a very low dosage of antihistimine blockers i.e. diphenhydramine. Diphenhydramine does cause drosiness and you'll find it under the brand name "benedryl", but any generic imitation will due as long as it has diphenhydramine in it. If upon taking the antihistimine you notice the itching ceases, then you should know that its most likely an allergic reaction. Don't worry though...people can be allergic to many things i.e. grass pollen, mold spores...doesn't mean it'll kill you...but if its unbarable, then I'd ditch it and try another brand. If another brand of the same substance doesn't cause the itch, then you're either allergic to the oil that the anabolic substance was dissolved in i.e. "sesame, conttonseed, safflower" or its just straight up funkdafied dirty ol gear. Don't give up on the gear right away...it might just be the brand.
Good Luck!
