Metabolize, not amortize!
100mg T ester will absolutely shut you down
Your levels after 8 weeks may be in the 800-900 pg/ml range. But we do see guys who fall outside of that both ways.
One week after a single injection, T levels will be quite low as residual E2 keeps your own production from starting up.
With repeated weekly injections, levels at the end of 7 days can be low enough and E2 levels high enough to make many feel a mess.
100mg T eth/cyp yields about 70 mg T or 10mg T per day from 100mg/week. Many toss out that T production of a youthful virile male is around 10mg, not 7mg.
It is not clear what you are asking or needing.
