I used IGF1 LR3 from a good source in China. Since I was a long standing customer, he offered money back guarantees on his IGF1-LR3. I followed what you said... and exactly what you said. I was so dumb to take Humalog with it... I had to drink nearly 1 litre of pineapple juice, a box of tim-tams, 3 bananas, 2 bags of skittles and 2 bowls of ice cream to STOP the hypo effect.
When I tried with another brand (won't name brands - as not to appear bias or discredit any particular brand), with Humalog like before... NOTHING.... garbage.
