Gary Brecka covers three ways to get peptides into your body: injections with bacteriostatic water, skin lotions like Peptool's copper peptide for wrinkles, and nasal sprays for NAD and BPC157. Copper peptides stimulate angiogenesis and improve fine lines. NAD can't be taken by mouth but works nasally.

Reconstitute with bacteriostatic water and administer via subcutaneous injections.

Peptool's GHK-Cu (copper peptide) formulated into a lotion/base formula.

NAD, BPC157, and TB500.

NAD cannot be ingested orally but can be delivered through the nasal cavity.

So there's so many ways you can do peptides. Lots of people are used to injecting them. It's probably the least preferred route. But you can inject them. You reconstitute this with bacteriostatic water and then you do subcutaneous injections. You can also deliver them through the skin. This is Peptool's GHKCU copper peptide. So it has a base formula and then peptides that are mixed into the lotion. So it goes right through the skin and delivers the peptide right into the skin. Copper peptides are really good for fine lines and wrinkles and also causing angiogenesis, new blood vessel growth in the skin. And that's kind of the name of the game if you're trying to get more youthful skin. You can also do them in a nasal spray. I use a lot of these for NAD, BPC157 and TB500. Those are healing peptides. And also the NAD molecule, which you cannot ingest orally, but you can deliver through the nasal cavity. But my wife absolutely loves the skin Peptual one. With the ghkcu, your skin will look absolutely beautiful.
