Everything you need. Nothing you don't.
Most serums bury two working ingredients inside forty-nine. We build the opposite: a handful of peptides at the concentrations actually studied, and nothing else along for the ride.
The category had a filler problem
Most peptide serums pick a side, GHK-Cu or other peptides, rarely both, then dilute whatever is left with hyaluronic acid, vitamin C, and botanical extracts. It looks impressive on a label and quietly drops the active concentrations below what the research actually studied.
We started PLU to make the version that didn't exist: focused dual-peptide formulas, at meaningful concentrations, with nothing added for the label's sake.
Short ingredient lists
Six ingredients or fewer, every time. You can read and pronounce every one.
Meaningful concentrations
1% actives at the levels examined in published research, not trace amounts dropped in for the label.
Made in the USA, 30-day returns
Formulated and produced domestically, backed by a 30-day money-back guarantee.
Nothing hidden
No hyaluronic acid, vitamin C, or botanical filler. Layer those yourself if you want them.
Built by a family, around a short list
PLU started the way a lot of good things do: with brothers and a problem none of the products on the shelf could solve. One of us had tried minoxidil and dealt with the irritation. Another went deep into the published research on copper peptides.
Sourcing them meant gambling on overseas suppliers, six to eight week shipments, and concentrations that rarely matched the label. So we built the thing we wished we could have bought: peptides at the concentrations actually studied, and nothing else. We run it like a family operation, because that is what it is.
Still writing to you as Pete & Lu.
Three focused formulations
Each PLU product is built around its peptides and nothing more. Everything else is dilution.

Frequently Asked Questions
How long until I see results with copper peptides?
Real results take time and consistency. Most users notice initial improvements in skin texture or hair appearance within 4-8 weeks of daily use. Significant changes in skin firmness appearance or hair density typically become visible after 3-6 months of consistent application. The founder's before and after photos represent years of daily use - quality copper peptide formulations work, but they require commitment.
Can I use Face Tonic and Hair Tonic together?
Yes, absolutely. Both products work through complementary peptide mechanisms and can be used together as part of your daily routine. Apply Face Tonic to clean facial skin and Hair Tonic to your scalp - both absorb in seconds. Total application time is under 60 seconds for both products. Many customers use both products daily for comprehensive peptide support.
Why don't you include hyaluronic acid or vitamin C?
We exclude hyaluronic acid, vitamin C, and botanical extracts because they dilute peptide concentrations below the levels studied in research. Our philosophy is pure peptide delivery at meaningful concentrations - you can layer other actives like hyaluronic acid or vitamin C separately if desired. This approach ensures you're getting the exact peptide concentrations examined in published research, not diluted formulations that compromise efficacy.
What makes PLU different from other peptide brands?
Three key differences: (1) Dual-peptide systems - we combine GHK-Cu with complementary peptides like Palmitoyl Peptides or Acetyl Tetrapeptide-3, not just GHK-Cu alone. (2) Meaningful concentrations - 1% GHK-Cu, Palmitoyl Peptides, 1% Acetyl Tetrapeptide-3 match the levels studied in research. (3) No filler dilution - we don't mix in hyaluronic acid, vitamin C, or botanicals that reduce active peptide concentrations. Just 6 ingredients per formulation focused on maximum peptide delivery.
How do I use these products in my routine?
Face Tonic: Apply 2-3 drops to clean, dry facial skin once daily (morning or evening). Allow 30 seconds to absorb. Layer other products separately if desired.
Hair Tonic: Apply 2-3 drops directly to scalp in areas of concern. Massage gently. No need to rinse. Use once daily on clean, dry scalp.

If it isn't doing something, it isn't in the bottle
No hyaluronic acid, vitamin C, or DHT blockers. Just the peptide complexes studied in published research, verified for concentration, and used in under thirty seconds a day.
