Shoppers interested in a botanical-and-peptide blend and willing to compare recurring costs.
Anyone avoiding alcohol or aromatic oils, or relying on an older formula review.
What is in the formula?
Caffeine · Botanical extracts · Named peptide ingredients
The current US list includes Nicotiana benthamiana-derived peptide ingredients. It also lists denatured alcohol and bergamot oil. Copper Tripeptide-1 is not listed.

Our assessment
GRO illustrates why a review needs a dated ingredient check. The current page includes named peptides alongside botanicals, so a blanket description of the product as “peptide-free” would be inaccurate. Equally, the presence of a peptide does not make it a copper-peptide serum.
The practical choice is whether this exact formula fits your preferences at its full recurring cost. Do not compare a subscription introductory total with another brand’s ordinary one-time purchase and call the first one cheaper.
Read any study claim together with its method. A person reporting fuller-feeling hair after several months can describe a meaningful cosmetic experience, while still leaving open how much change came from growth, breakage, styling or perception. That distinction is central to our verdict.
Reasons to consider it
- Current full ingredient list published
- A combination of botanical and peptide ingredients
- Consumer-study design is identified
Trade-offs to weigh
- Contains alcohol and aromatic oil
- Consumer perceptions do not measure new hair directly
- Subscription terms need attention
What the evidence supports
The current page reports a 120-day consumer-perception study of 40 participants. Those results describe what participants reported, not a controlled count of newly grown hairs.
We have not tested this product or measured hair counts. Product placement reflects ingredient transparency and shopping fit, not a claim of superior regrowth. Read our guide to clinical claims.
Routine considerations
The brand describes daily scalp application without rinsing. Check the current pack and formula rather than copying instructions from an older GRO review.
Buying in the US and Europe
Compare the one-time purchase and subscription separately. The current page asks for cancellation five business days before renewal; verify the terms shown for your order.
Confirm the complete checkout total, exact pack and one-time or recurring purchase selection. Our routine cost calculator can help compare your own numbers.
