with big pharma brands like lilly, pfizer, novo nordisk, etc, you don't really need to get bloods, you can just verify its legitimacy online by the UPC numbers on the box.
i'm not sure how much experience you have with GH, if any at all, because 5iu is really a lot of GH if it's actually real humatrope.
i've used my fair share, only pharmaceutical, and 3iu was sufficient really. excellent excellent results from 3... but i also was on that dose for about 5 months. i'm on about 2.5iu a day of humatrope at the moment and i'm really happy with the results.
and unless you are literally trying to become a professional bodybuilder you do not want to go up to 5iu of this, let alone 5iu for only a month. it's literally pointless because the whole point of buying GH is to actually BE ON GH and to ride the wave for as long as you can because it's the best shit ever. try running 3iu 5x a week and if you feel the need to go up then do it. although i don't think you'll have to if you train right and eat right.
well said that
