doxycycline

Does anyone know the half-life of doxycycline?

[Drenten]

Serum half-life is about 16 hours.

I have 100 mg pills...is that the same half-life? I was wondering whether I will get better results by taking once a day or splitting up and taking twice a day.

[Drenten]

Usual dosing is 200mg on the first day followed by 100mg per day from there on. This will give you a very effective concentration of doxycycline in your system.

Oral tetracycline has a very low bio-availability comparatively to doxycycline in the presence of food. That’s one of the reasons why it takes much higher mg amounts and more frequent administration of oral tetracycline to maintain high enough serum levels to be effective.

Since bodybuilders usually eat many small meals throughout the day, oral tetracycline isn’t a very good choice for us.
