I was surprised at how strong 1,3DM products were the first time I used them (original AMP, dosed at 2 caps, felt like...awesome.)
Also surprised at Epi* products, those went extremely well for me (compared to previous PP & SD runs.)
The focus from made me say Woah, and say alot more that day
Last but not least threw me for a loop the first time I used it. Felt like a test + vitamin B injection (immediate results)
Those are the products off the top of my head that stand out the most! Looking forward to trying some of the others mentioned here.
