We carry real, high quality IGF-Lr3 at Blue Sky Peptide.
It's not tren, but it's good stuff. You still need to be careful though, you can't think that just because "it's not an AAS" that you can get crazy with it. Some people wish to have a glucose/blood sugar meter before starting research, and carrying a sugar product like gatorade at all times with Lr3 in case of hypoglycemia, since some research subjects seem to occasionally experience this as doses get dialed in. Also, don't be impatient and push the dosage up too fast. Start low and assess subject's tolerance first. Then adjust up slowly.
there are also GHRH and GHRP peptides that are pretty mild and increase GH release that might help, but I think the Lr3 will give you much more pronounced effects
Good 'ol testosterone isn't so bad either, and carries very little risk when used properly and with the right ancillaries
Good luck brother
