Depends on the cycle.

If your on a short/burst 30 day cycle I would inject 100mg/day for 10 days

If your on a cycle that most refer to, I guess 100mg 2 x a week for max 8 weeks.

Why would you do tren hex before enanthate? It doesn't make sense to me.

I would do the reverse and get yourself cutup toward the end of the cycle not bloated. ????
