Here’s a simple tip: grab one kit from each source, and if your budget allows, throw in a pharma option like Pfizer Genotropin 36iu. Try them all and see what actually works best for you.
From what I’ve seen, SSA runs about $50 for 100iu plus shipping, Lobster is around $65 for 110iu + shipping, and you can also get Pfizer through Lobster - $160 for 32iu, if you’re feeling fancy. Everything gets delivered, you test them out, and that’s it. Most differences will be pretty minor, though SSA seems to cause a bit more water retention for some users.
As for Lobster - I’m running his HGH right now and honestly, no complaints. It reconstitutes noticeably faster in bac water compared to Q and Opti. Plus, you’ve got Jano test results and plenty of user feedback backing it up.
