Current protocol is 100 mg ew test cyp, hcg before test shot on Saturdays. I broke up the test to twice weekly but the syringes I use are 3 ml syringes and am probably not getting the full dose. Questions are these: my hcg pins are 3/10 ml and the needles aren't interchangeable. How much is 1/4 ml in units on a 3/10 of a ml pin. Gauge on needle is 31g. Needle length is 8mm. Secondly if I do hcg the day prior sub q, does that affect anything? Thanks
