How much HGH were you planning on using? I find the amount needed varies massively from supplier to supplier. For example when I used hygetropin a few years ago the stuff was incredibly potent. 4ius EOD or so was more than enough. But Ive been using Kigs recently and I shoot 10iu in one go and I swear the stuff isnt even as powerful as 2iu of the hyge. Human grade stuff is even more potent.
What im trying to say is you might not need as much as you think depending on the brand.
That HG bac stuff is the bomb. Probably not as good as grapefruit juice but a close second.
