Just a quick review. Just finished 8 weeks of orig1n. About 5'9" and started at around 170lbs. Stayed at maintenance calories or slightly above. Dropped about 4 lbs scale weight and noticeably leaner. Measurements are up slightly and strength increased throughout the 8 weeks in terms of reps and or weight. Was shooting for a bit of recomp and adding a bit of size. I'm old and have been training consistently for too long to count. I would call it a success and would recommend the product.
