Use half an ampule every 5 days subcutaneously with an insulin needle, reverse load the oil, use the skin on the upper thigh, its a less painful shot results in less bloat and more stable levels, using a full dose a fortnight just gives you higher than normal levels for a few days before slowly crashing, personally i would use enanthate over a blend but the 5 days will help with the blend, i have used previously and have been able to get 7-10 days between shots the goal at our age should be to get the benefits on as less as possible, just my two cents
