Wolverine, Glow & KLOW, Compared

Our three signature stacks get asked about more than almost anything else in the library. They share a common foundation, each one builds on it a little differently, and picking between them mostly comes down to what you're actually trying to support. Here's the plain-language breakdown — including a proper introduction to GHK-Cu and KPV, two ingredients that tend to get undersold as "just a skin thing."

The Shared Foundation: BPC-157 & TB-500

All three stacks are built around BPC-157 and TB-500, two peptides widely explored for soft-tissue healing and recovery — think training load, injury rehab, and general wear and tear. If recovery is on your list at all, you're starting from the same place no matter which stack you land on.

None of these are FDA-approved. All three require a current CMP and CBC, and all three go through provider review before approval, same as everything else in our library.

Wolverine: Recovery, Nothing Else

Wolverine keeps it simple — just BPC-157 and TB-500, in a 5mg/5mg, 10mg/10mg, or 20mg/20mg combination. It's the one to reach for when recovery is the whole goal: active rehab, a heavier training block, or general recovery support without adding anything else to the mix.

GHK-Cu: More Than a Skin Peptide

Before getting to Glow and KLOW, GHK-Cu deserves its own introduction, because it's usually flattened down to "the skin one." That undersells it. GHK-Cu is one of the more well-studied copper peptides out there, with a research history that goes back decades — most of it in wound healing and tissue repair, not cosmetics. It's been explored for its role in stimulating collagen and elastin production, supporting the skin's own repair processes, and general anti-inflammatory and antioxidant activity, alongside the firmness and skin-quality effects it's better known for now.

That dual identity — repair-oriented and skin-oriented — is exactly why it shows up in two different stacks below, for two different reasons.

Glow: Recovery Plus Skin Quality

Glow adds GHK-Cu on top of the BPC-157/TB-500 foundation, leaning into its collagen-support and skin-firmness side. It comes in two concentration tiers, Glow 50 and Glow 70, and it's the stack to consider if skin quality is part of what you're working toward alongside general recovery.

KLOW: Recovery, Skin, and Inflammation

KLOW is our newest and most complete stack — GHK-Cu, KPV, BPC-157, and TB-500 together. The addition here is KPV, a small alpha-MSH-derived peptide best known for broad, systemic anti-inflammatory effects — it's not limited to any one area, which is part of what makes it interesting. That includes gut-related inflammatory support, but also inflammatory skin conditions and general systemic inflammation more broadly. Paired with GHK-Cu's repair and skin-quality profile, KPV rounds out KLOW into a stack aimed at recovery, skin, and inflammation together, rather than just the first two.

KLOW is worth a look if you've been considering Glow but also deal with inflammatory skin issues, or if you want the broadest of the three stacks in one protocol.

How to Think About It

A rough starting point:

• Recovery is your main goal → Wolverine
• Recovery plus skin quality → Glow
• Recovery, skin, and inflammation → KLOW
• Not sure → Bring it up with your provider during your labs review — this is exactly the kind of decision that benefits from an actual conversation, not a guess from a product page

Same Process, Any Stack

Whichever one you're leaning toward, the path is identical: submit your Base Panel (order through Quest at cost, or attach results from the last 12 months), a provider reviews everything before approval, and you're on a standard 90-day retest schedule from there.
