Just picked up 300iu of the new Jintropin AQ. Looks pretty good. I've been on regular Jintropin for about 8 months at 5iu a day and been very happy with the results. It's a little pricey but I'm going to treat the Jintropin AQ like Nutropin AQ and assume it's at least twice as potent, if it is it will be worth it. Start at 3iu a day of the Jintropin AQ and see if I get sides. The pen delivery is great, cuts down on the hassle of twice daily administration big time. Will let you guys know how it compares.
