Oratropin is actual IGF-1 in a IBE's "cell mediated" oral delivery system. Although I have not personally tried it, many others have had very positive experiences with it. The delivery system is said to be absorbed through the soft tissue in the back of the throat/mouth and be systemically active for 24-48 hours...The delivery system otherwise is a mystery.
One month of LR3 IGF-1, following a 5on/2off dosing schedule with 40-60mcg (bilateral) per dose will usually cost you about $200, however, chemistry-labs is having an amazing sale right now and selling 1mg for $100 versus $130 for the Oratropin. Depending on your budget and your feelings about pinning, both are good options...Hell, I say give both a try and see which you like better.
This post is in no way comprehensive....do a search on oratropin, IGF-1, and so on.
