First time using peptides or anything considered to be unnatural and I got some pretty great results. I ran 80 Mcg of IGF-1 LR3 four times a week for three weeks post workout and gained 10lbs. Within the first week I noticed the incredible pump, along with the weight gain I was seeing which was 4lbs in one week! The second week was about the same ending the week about 6-7lbs heavier. The beginning of the third week I noticed the strength gains, along with the awesome pump and more weight I put on, which ended my third week at 10lbs gained. The only side effect I noticed was some water retention and bloating during the second week of my cycle. I also noticed I slept better, not waking up during the nighttime, I recovered much quicker, healed faster and just felt great! Going to wait out my post cycle for a few weeks then get back on the IGF-1 LR3. The only thing in my diet that changed was an addition of some protein powder, and I have previously been stuck at the same weight for about a year. This stuff is amazing!
