I've never been able to tell much difference between sus/E/cyp. Sus was designed for TRT and only meant to pin every 10-14 days or something. But IMO it should be pinned more often since the short esters drop off. I prefer test e. can pin once a week if you want. Also I wouldn't bother with 250mg/wk. just start with the 500! The adex will help with the bloat also! .5mg EOD should be fine. Good luck bro!
Actually, using Sust 250 would be fine, you will notice the short esters "kick in" sooner than the longer Test E/C esters. I've never heard of any burn or negative sides from injecting Sust...PCT is over rated...
the prop in sust will burn especially for someone that has never introduced their body to esters ...... my very first run was with organon sust and it did burn
