Picked this SIS Test E 300 up from PharmaComStore and did 900mg a week for 3 weeks then the final 300mg at the start of week 4. Waited a few days after that last injection and went and got tested. You can see where I started from I had labs done before the first injection and I was at 2163 and after testing over 3,000. I was a little let down that the final number just says greater than 3,000 it would have been nice to see an exact total but that's not how the labs do it I guess. Anyway I felt great lifts and strength was going up each week and I feel that SIS products are dosed properly I would def purchase again. The entire process of ordering, paying, and receiving the product from PharmaComStore was flawless great place to shop
