Been on for around 3 weeks now on the 290iu kit, splitting each vial across 7 days. I believe the vials were rated as 27-29iu (the one vial they sent to jano hit 29iu), so my dosing was somewhere around 3.8-4.1iu/day. No additional anabolics or medications that would interfere with my IGF score, only TRT dosing and general health supplements. Thyroid testing can be disregarded, I had that done to check some other things. I did not get baseline IGF because its traditionally always been in the mid 100s for myself (I can dig up old labs if anyone cares). I also did not get serum GH testing because i was more interested in the IGF response. Sides and the effects I'm receiving are consistent with 3-4iu of gh daily, so im pleased with this. No red welts, swelling, or any sort of local irritation. GodT had incredibly quick T/A time, and I think I got more than my moneys worth with this kit. I'll be ordering more and probably do another IGF test at 5-6iu daily.
