Madman, in your 2017 study using TC sub-q, looking at figure 2 graph, two patients had peaks on days 4-5, one peaked on day 7, the rest peaked either at 6 hours or 1,2 and 4 days. Many had a lower level at day 3, meaning levels at day 2 and day 4-5 were higher than day 3.
The person who peaked on day 5 had a total 100 mg dose as was close to 900 on day 7, falling from the peak 1400 on day 5.
Maybe I could conclude that there is a 90% chance that day 7 will be lower than one of the previous 6 days after a sub-q injection, though which day would be the peak seems all over the place.
The op said he takes 180 mg and measured 1024 ng/dl on day 7. That seems reasonable and a guess would be his peak was around 1500-1600, though what day is anyone's guess, likely day 4-5, though who knows. I say likely because his total T was still 1024 on day 7.
Maybe the day you peak is related to total initial dose, though one can only speculate from such limited data as 11 females undergoing FTM transgender hormone treatment.
"There was a significant inverse relationship between intraindividual CV and body mass index " the lowest BMI of this group was 20.2, average 28, though I am not sure what to make of that.
And perhaps males react differently to Test-C than females.
