When I say in range I'm talking about the range that would be considered naturally achievable, so less then 1200. Your boost up to 1100 is massive, but it wouldn't be considered supraphysiological testosterone. So what I'm getting at is I don't think the 4ad or 4 Andros have the ability to induce those types of levels one would consider enhanced from a testosterone standpoint. So if person was running 300mg of testosterone his levels would likely be 2000 or higher, at that point I don't think the 4ad would continue to raise testosterone levels and even if they did, I don't think there's much of a difference from a muscle building standpoint between a 2200 and a 2600 reading.
Now someone in your position might say, ok I have limited testosterone supply. Maybe il do 50mg of test per week and add the 4ad to pick up the slack. Save the extra testosterone for down the road and once you have enough maybe run 250-300 for 6 weeks for a nice little boost
