I know about 5 guys that have all purchased humatrope that turned out to be fake.
Sometimes you may trust your source with your life and he may trust his source above him,, but the guy above THAT GUY is getting scammed... or anywhere in between
everyone likes to think they can trust their source but I have seen some very credible sources sell this stuff that turned out to be fake so IMO its not worth the risk.
If your source is stupid enough to believe this would be $300 then you need to find a new source because hes an idiot... if this isnt the case then he is intentionally trying to scam you... either way, the fact that your source offered this to you is a huge red flag that you need a new source...
If my source offered this to me, we would have some serious words and probably end up dancing lol. Because hes either retarded or trying to scam you bro... it should be somewhere between double and triple that price.
