Just a side note. Red welts is reported on serostim by the fda. So it's totally impossible to happen. As does genotropin. They also list a ton of other side effects like rapid heart beat ,fever, so saying a medication never has side effects is not a real accurate statement. I'm not saying none if what u said is possible but a lot if what has been said is a pretty big accusation
If that's your analysis of what an ARTHUS reaction is, your in error!
And oh yea the chances of an ARTHUS RX occurring with rHGH is indeed VERY remote bc it's identical to endogenous lay produced GH.
The reactions are HIGHLY idiosyncratic while one patient may experience a gamut of signs and symptoms, another mate will only develop arthralgias and some have no complaints whatsoever.
There are some well a stablished RF for this reaction but suffice it to say if "you" have a history or allergies the prob of an A-RX increases.
