Through labs I know Testosterone Cypionate provides super stable levels when injected every 5 days. Like I injected tonight. I will inject again Sunday. If you're running 750mg per week that is 3000mg a month. So that means every 5 days you inject 500mg. IMO and proof of labs that would give you ideal levels. My levels 2 days after my injection were only like 25 more than the day my next injection was due. Every 5 days with Cypionate is the ticket.
