The timeline
One bottle of the Follicular Serum covers 6 weeks of nightly use, 1 pump a night. The study in Note 09 ran for 12 weeks and took its result at the end. So the course is 12 weeks, and 12 weeks is 2 bottles.
That fixes the timeframe the evidence belongs to. The figure we cite describes week 12 against a vehicle control. It is not a figure for week 4 or week 8, and there is no data for any longer period. When you read the program's evidence, you are reading a 12-week, 2-bottle record.
It also shapes how the serum is sold. The Standard protocol is 1 bottle, the first 6 weeks. The Advanced protocol is 2 bottles plus the Scalp Reset Serum and the written guide, the full course. If you start on Standard and want to complete the 12 weeks, order the second bottle by week 4 so it arrives before the first runs out. Note 15 covers that.
Every order ships from stock in the United States, in one shipment, within one working day.
How long is one bottle of OF·27?
Six weeks of nightly application, one metered pump a day.
What does the cited study's timeline correspond to?
Twelve weeks, two consecutive six-week bottles, with the measurements taken at the end of that span. There is no data for any longer period.
