I am unaware of any Real SARMs on the OTC market that work, or for that matter black market that work.
IGF-1 will be a fight to the end if it works or not. I would just go with that GH is just a better alternative that we know works. If you are going to spend the big bucks then stick with GH. I have used IGF-1 Long R3 3 times. First time Loved it, the remaining I didn't even notice it. No hypoglycemia, no growth or anything. First time, i did notice a little but not enough to drop $200 on it again. Better alternative for that much money.
