I would advise doing 12 weeks of strength training before starting a hypertrophy program. you will gain so much more out of it.
Streamline - not sure where you got that info from.
This way you'll be stronger and you'll be able to gain size easier.
I got the info from my college tutors.
It's the other way around, if you do hypertrophy first you'll be bigger and have greater gains in strength.
