i got masshgh in mail on fri, used it fri and sat nights, matter of fact i just got up a little while ago. the formula must be somewhat different than other hgh products i have tried [hghpro/hghup] as those 2 actually interferred with my sleep until my body got used to them...mass hgh effects seem more in line with powerful which from the start improved my sleep. looking forward to better sleep/better recovery/some leaning effect/and a boost in libido...i have been impressed with the other lecheek products i have used, so i expect good things!!!!
