Thats expensive. Look around some more you should be able to find it cheaper.
Theres also a ton of info out there already written about igf1-lr3. Do some searching for that too.
I would really recommend you do a lot of research before using. Its an interesting peptide but its not
AAS. If you go in expecting those kind of results you will be very disappointed.
In short. If you have capped all your gains you can make from diet, years of lifting and
AAS's then maybe it would be a useful peptide. Other than that there are better ways to spend $145! Like a lot of chicken and tuna! You'll gain more muscle, I promise!
