It's close to a hundred on this forum alone, excluding ones without bloodwork details.
There were plenty, none of us have a clue where you got that from, probably another chat GPT prompt. There are plenty of report from before 2023 and there's absolutely 0 reason for anything to have changed since then, as nothing has.
You are the only one ignoring basic logic. If E2 is lower after having injected it and nothing else has change, primo acts as an AI. Again, nothing was different in 1999-2023 other than we have more frequent posts now, as for example in my country there was internet in maybe every 10th households for a third of that time period.
We still have yet to deny anything they've said. Primo might not have strong enough affinity to the estrogen receptors in breast tissue. That's completely irrelevant when it comes to serum E2 levels.
Masteron still has yet to see any bloodwork with reduced serum E2.
You keep repeating breat cancer treatments. Nolvadex doesn't lower E2 either, it's still literally known to reverse gyno by getting rid of some of the already build and rock solid tissue. Boob size and serum E2 are barely related other than in extreme cases of high E2 or more likely fluctuations in E2 and progestogenic activity.
Multiple people have explained why you are wrong. Atleast try to ask Gemini of something, you chat GPT is clearly not accurate.
