How long do I have to use hgh before testing igf1 levels?

[Rick Kane]

I read normal protocol for testing is intramuscular 5 or 10iu depending on pharm or ugl grade and GH serum test at 2.5-3hr mark after injection

That's only if you're getting a gh serum test.
The IGF test is done exactly as Scotchguard described. 1 hour post SC injection.
One important thing to keep in mind about IGF tests is to know your baseline before testing your product. My baseline ranges from 140-180 and 4ius raised my score roughly 250 points.

It's not an exact science but pharma grade should raise your IGF 100 points for every 1iu. That number can be higher when gh is combined with AAS.
