The purpose of this study is to assess the bioavailability of total testosterone through pharmacokinetic profiles obtained following (a) single administration of three doses of TBS-2 b) multiple administration TBS-2.

In addition, assessing the bioavailability of free testosterone, dihydrotestosterone, SHBG and estradiol through pharmacokinetic profiles will also be conducted.

Detailed Description:

This is a 2 Period study that requires overnight stays in clinic. Blood samples are required at all visits including sampling at predefined time periods during the overnight stays.

Period I

Subjects will be checked-in on Day 1 Period I to start their baseline testosterone measurement (dependant on menstrual cycle, preferably within 48hr of start of the menstrual cycle). They will remain institutionalized until Day 4 morning, and will be checked out after the 48 hour blood draw and study close-out for those that do not continue with Period II.

Period II (Multi-Dose)

Subjects will be institutionalized starting on Day 1 of Visit 3 until Day 5 morning of Visit 3, and will be checked out after the 48 hour blood draw and study close-out.


Ages Eligible for Study:   18 Years to 40 Years   (Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
