Same experience, including 3.5ml, except I got very brief AM carpal at 4iu/day which stopped after a couple of weeks.I've been using it, seems to be very similar to the 40.8iu Opti gold tops I have. I notice transient carpal tunnel symptoms about 2-3 hours after injection with both at 7.5iu/day, but not at 7iu/day.
Both reconstitute clear too, just make sure to break the vacuum and let the water stream down the side of the vial, you don't want a jet from a large gauge needle hitting the puck directly. Both are also painless with Hospira BSW.
I reconstitute with 3.5ml which is close to a complete fill... I try to keep concentration as close to 10iu/mL as possible with GH. The puck will dissolve with less, but figure there is less chance of aggregation/dimerization at lower concentrations.
Previously I used K4L Supreme (~ 30iu) which did not give any carpal tunnel symptoms even at 7.5iu and tended to mix slightly cloudy - also would frequently notice a little sting at the injection site.
I also filter, and have detected no increased resistance with a 13mm Pall .22um PES filter for the entire vial, vs a K4L Deluxe, 18iu, which clogged 2 13mm filters and required a 3rd to get through a single vial.
