What this video covers
Ones like the BPC-157 are a bit more resistant because that’s where they’re made, in the stomach acid. The exception to a lot of the rules that we applied are these orally bioavailable peptides, in that, it’s made there and it’s resistant, but ones like KPV or GHK-Cu or the TB4 fragments, they’re more fragile. And that’s why we have to be intelligent in how we take them and how we buffer them, or also how we deliver them. Ben Greenfield: Well, I’ve been looking forward to this interview for a while.

Key points, in the speaker’s own framing
- The exception to a lot of the rules that we applied are these orally bioavailable peptides, in that, it’s made there and it’s resistant, but ones like KPV or GHK-Cu or the TB4 fragments, they’re more fragile.
- And that’s almost reactionary to the compounding chemists that do have the FDA approval.
- The biggest knock on peptides that I see and I have to acknowledge is there is a very clear lack of human evidence there’s a lot of animal evidence, but human evidence, it’s just not being done because they’re not patentable.
- Kyal Van Der Leest: But ones like KPV or GHK, copper or the tb, four fragments, they’re more fragile and that’s why we have to be intelligent in how we take them and how we buffer them or also how we deliver them.
- Yeah, together with KPV, which is an antimicrobial, anti inflammatory peptide, they work really well in synergy to basically fast track your gut healing as best they can.
- That’s where people sort of might associate the tb 500 with the musculoskeletal repair and regeneration and the wound healing, and just sort of the other part of the wolverine stack that people say.
