I'll be back on stage in 2018 to qualify for National level shows. Currently bulking and a "semi solid" 252 at 5'8. Basically it's between breathing comfortably or eating. I choose eating at the moment.
On SEOs, I had a complete bicep detachment about 4 years ago at the shoulder insertion and it affected the appearance of that bicep from all angles. I considered SEO usage to try and improve the appearance of that one muscle. Not make it larger, only to correct damage I can't correct no matter how much I train it (change the look somewhat). I've decided that if that's the only reason I lost to someone or was told that was a major issue then perhaps I'd consider it personally but until that happens it's not for me.
To me the difference is all other PEDs still require hard training, diet and effort. SEO's do not require any effort at all. 2 injections a week of 3+ cc's and suddenly you've gained an inch or more in your arms or calves. You want upper pecs, just shoot some SEO in there and there it is. It's just not that same as working for it IMO.
Regarding competing and SEOs, if you get beat by a guy that's using SEOs and that made the difference in him beating you then so be it. You should have worked harder. Anyone competing knows its a free for all and there are no rules. Plus size is only part of the criteria for winning shows.
It's mostly about taking pride in working for the muscle I have. I don't see how anyone could get that from shooting SEOs but that's just my opinion.
