The first blend is GHK-Cu, BPC & TB, the other one is those three plus KPV. My sister takes the first and I take the second lol. Before this I took a different stack and loved what it did for my hip & gut!
I wonder whether the combined blend works worse than its separate parts. I saw great results with TB plus BPC and not much with the blend. Maybe mixing these peptides makes them break down. Could be pure coincidence, other things changed too, but that is my first hunch.
I badly sprained my ankle 3 weeks ago. Peptides beyond GLP1s never interested me, but a holiday was coming so I tried the GHK blend. The ankle isnt healed and the hiking part got cancelled. My problem is I cant tell if it did anything, since I have no comparison for what happens without it. Now I'm debating what to do when I'm back. BPC and TB500 tempt me again, but GHK Cu sounds like too much hassle. Maybe KPV too, though TB500 and KPV might just add cost for things with hardly any testing.
Tesa and ipa tend to trigger allergic or systemic reactions more than HGH does, and stacking those two seems to raise the odds even further. Reta is about the only item nearly certain to deliver visible, positive results soon. All the rest is hope and a prayer. That said, lots of folks run reta with the blend, or part of it, plus a GH peptide. For me the blend's ingredients and the GH peptides didn't impress, so I won't be restocking when I run out.
