I have never heard of anyone only taking 3 IU/day. Nor have I heard of anyone taking GH without anabolics through the whole GH cycle, as well as insulin and T3. My guess would be that you would see very minimal effects. GH by itself (no anabolics, no insulin) will not do very much. No reason to do GH at a "low medical dose" unless you got a lot of cash to burn. Considering the effects versus the cost, I wouldnt bother. But, hey, if you got the money, it would be nice to try out . Oh, and you said "resonable price"... be careful. Make sure you know what your getting. GH is easy to fake.
