I`m going to start slin with my AS cycle I`m currently on. I`m fine with the syringe with U-100 prep. I want to know what size gauge, and if the longs or shorts is easiest for injections. Keeping in mind that I will be injecting 8iu`s 4 times a day. That will be 4iu`s Humulin R and 4 iu`s Humulin N. One upon awakening, another 4 hours after awakening, and another post workout. Any input is greatly appreciated.
