Well I myself do notice the nice pump from 3 pills, I also notice the lethargy late in the day so I take mine mid day or right at the end around my workout since the stim or well being feeling only last a few hours on me.
Strength gain from 1 to 5 I give it a 5 being the best ph in regards to strength I've used yet
Pumps-5, being that the pumps are so crazy I have the energy to do more reps but cant cuz of the pump. Good and bad thing
Hardness-5 I like hdrol and tren products stacked for the hardness and strength gains I'm getting from this product.
The list goes on and all of this is from 3 pills I feel I have no need to go to four since I'm 215 now and dieting to 185-190
Best thing tho, is I'm not over eating like I was and losing weight (fat on my diet) and my strength and well being is still going strong.
In regards to pct 2nd gear itself is a great product, I havent used it yet but if you research the ingredients you'll see what I mean. Also a friend of mine used it recently and liked the product.
