I don't think such a small amount will have a significant impact.
My AM routine the last 8 weeks of my contest prep was...
- 5:00 AM... 3-4iu Humulin R
- 5:15 AM... 5ml Synthetine
- 5:30 AM... HIIT session (duration varied...started at 5 minutes warmup, 15 intervals, 5 cool down and finished around 30 intervals)
- 6:15/6:30... Breakfast (Started at 6 whole eggs with 1/4 cup whites, ended at 2 eggs, 1 1/2 cup whites...coconut oil was used as well, in varied amounts)
As stated, this was my AM protocol for prep and my condition was the best I've ever achieved, so I see no issue with this small amount of insulin that far ahead of a fat meal.
I have been using it with my pwo shake that has 40 mg simple carbs. I don't think I could use insulin again, BC the first time I used it pwo I went severely hypo. I am prone to hypo since childhood.
Have been using synthetine pre wo for 45 days or so. Have dropped three inches on my waist. So it still must work somehow. Or it is the placebo effect and just watching what I eat and more frequent workouts.
