Ok, let's see why twice weekly IM injections of a compound like Test Cyp is better, for the most part, than one larger dose injection per week.
It's all about the half life of the drug. Test Cyp serum levels peak at about 72 hours after injection for most men (were all different so it's not exact). Half life than is about 6 day; this means half of the drug has already been metabolized by about day 6.
The idea with twice weekly injections is to get Testosterone serum levels to be as consistent as possible to avoid peak and troughs brought on by larger single weekly dose injections.
So, if you inject say Monday AM and Thursday PM you are essentially at about the peak of the previous injection thereby stabilizing Testosterone serum levels.
Larger single doses sees higher peaks and lower troughs which is not how the body metabolizes in its natural state. Additionally, by stabilizing serum levels reduces aromatase activity which is something all of us on a testosterone replacement therapy (TRT) protocol want.
For me, as an example, when I went to twice weekly injections I didn't need an Aromatase inhibitor (AI) anymore.
Some men claim to feel better on twice weekly injections as well due to the more stable serum levels as it eliminate the sometimes emotional roller coaster effect brought on by the single weekly injection.
If you miss a week of injections, like you ask, think of the drugs half life of 6 days and do the math.
Hope this helps you my friend.
