Been running test E for most of my cycles for the past few years but tried Sustanon on my last two blasts because the price was similar and a few guys here rate it. Honest take is I cannot tell a meaningful difference day to day at 500mg per week with twice weekly pins. Strength timeline was the same, water retention was the same, AI requirements were the same. The only thing I noticed was slightly more pip at the injection site with the sust compared to the test E I was running before. Anyone who has actually run both back to back with bloods know if the numbers look different or is it just marketing at this point?
