Bioequivalence and Bioavailability Forum

Dear All,
Are the below sampling points adequate for PK profile?
Median Tmax - 6 days
Mean half life: 26 days
Sub cutaneous: single dose
2, 12 and 24 hrs after administration. Additional samples were collected on day 2, 4, 6, 8, 10, 14, 28, 42, 56, 84, 112 and 140 days.
I have taken these time points from an article available in public domain.
Is there any method to calculate sampling point apart from method mentioned in BABE guidelines?
It’s a difficult to calculate time points for drug who has long Tmax and long half life.
Thank you in advance.
