So recently i ordered some igf-1 lr3 for my pct to help keep my gains and hopefully for increased muscle growth for lagging body parts. anyway to make a story short, my older brother is in the medical field studying medicine of course, and he was very interested in bodybuilding, he has his degree and what not, and he said in little world of doctor friends that know about these peptides that there is only one Pharmaceutical grade igf-1 lr3 and it's very fragile and it will only last 1 hour outside the freezer without harming it? so he said all this other stuff is fake. I'm very dissapointed as he also said even if it was real that igf-1 lr3 isn't for muscle site growth that rIGF-1... i don't know jsut a little upset right now knowing i purchased igf-1 lr3 hoping at least see some minor gains.
