I would say definitely yes.
Nasser super-sized in '95, but his arms didn't come up all that much from the previous year's NOC. In the front double-biceps, he was improved but still lacked a bit in the peaks; it was mostly his overall thickness that impressed.
Then, in '96, BAM, his arms got a lot bigger, and bigger still the next year. He filled out some more overall, too (10-15 lbs., some of which was in his expanding gut), but the localized growth was starting to look funky. IF it was escilene (sp?), he did a much shittier job applying it than Levrone ever did.
