What's wrong with pinning enanthate only once a week? I believe that is perfectly fine for a first cycle of 500mg per week. As I understand it, the active half-life of enanthate is 5-6 days. I understand that pinning enanthate every 3.5 days ensures more stability where blood levels are concerned, which is why I inject it twice a week, but again - it's his first cycle and a moderate dose to boot.
If you've never pinned before, I'd recommend going with enanthate. The total number of injections may not be a notable difference, but it certainly does simplify the matter, and pinning every other day may prove stressful. With that said, I use both esters in a cycle
