No it could be pollen, bea parts, bee's wax, who knows. I get massive buds without using massive or any other products. Base nutrients and a good environment are all I need to grow healthy lush plants with big yields.
As for Gibberellic acid, I was experimenting with it and other PGR's when many on this site were still in grade school so I don't need to google it. In fact I've done extensive experimentation with it in the past so I have experience with and understand what they are. A good grower doesn't need them to have great success.
Some stuff I still have.
