No ... Sust is multiple estered ... So it has short half life, mid half life and loooong half life esters incorporated ... Actually you only need to pin Sust once a week. Pinning 700mg every Mon is sufficient to sustain you until the next pin following Mon and so forth and so forth. If you pin it too often, then you keep the short esters elevated, the mid esters start to build up and build up and when the long esters start kickingin you experience this BiG ASS SPIKE and THAT causes your levels to fluctuate too much, especially when those start reaching the end of half life cycle.
^^^^^^^^^^ fuck yeah! that's the kind of info i like to see!
