It hard for me to answer the first part. There are factors that could change the results. When you injected is a big factor. Of course maybe a brand was dosed higher than the other. Maybe even a carrier oil was different and had an impact.
but over time, your body will find homeostasis. Thats why we need to take a break. When you go on your cruise, you want to go to the lest amount to feel normal. Like 200mg a week tops. It might take awhile to feel normal at that dose. You are using a lot of gear.
Since you are not able to train, there is no reason to stay on this dose bro so this would be an ideal time to drop the dose down. If you want to try to recover, this would be the time, but if not, for sure go to an HRT dose, at least for a couple months. Get your shoulder right and get some labs to make sure that everything is healthy before going back up.
