Hardly new, they have been around at least 10 years as I dabbled in them a bit back then, at least as far as things like BPC, SEMAX and SELANK. I would definitely not inject a random powder or solution sent to me from China without testing, I have heard of far too many dangerous mix ups and wrong orders. Anyways, I found them to be rather expensive for their effects. The human body is pretty fickle though, your brain can take a lot of abuse but eventually it will try to find balance, and then you will find yourself in trouble.
