@gaabfernandes's peptide routine claims, fact-checked

What does this video actually claim?

Gabriela Fernandes promotes using GHK-Cu (GLOW) and ipamorelin peptides nightly as part of her routine for improved health and performance. She claims GHK-Cu works as a reparative peptide at night, while ipamorelin stimulates natural growth hormone production during sleep when GH levels naturally rise.

The video positions these peptides as supplements for optimization rather than medical treatment. She uses both Monday through Friday, timing them before bed based on their supposed mechanisms of action.

Does the science actually support these claims?

The evidence for these peptides is surprisingly thin for how popular they've become. GHK-Cu has shown some promise in small studies for wound healing, but the research is mostly limited to cell cultures and animal models. A 2012 study by Pickart found improved collagen synthesis in vitro, but human trials are lacking.

Ipamorelin does stimulate growth hormone release. A 2005 study by Raun et al. showed it increased GH levels in healthy adults by 2-3 fold within 30 minutes. However, whether this translates to meaningful health benefits in healthy people remains unproven.

The timing claims aren't backed by strong evidence either. While GH does peak during deep sleep, there's no data showing ipamorelin works better at bedtime versus other times.

What's the safety picture here?

Both peptides carry risks that Fernandes doesn't mention. Ipamorelin can cause injection site reactions, headaches, and potential long-term effects on natural GH production that haven't been studied. The FDA hasn't approved it for human use outside research settings.

GHK-Cu appears safer but quality control is a major issue. These peptides aren't regulated like prescription drugs, so purity and dosing can vary wildly between suppliers.

More concerning is promoting daily use without medical supervision. Growth hormone manipulation can affect blood sugar, insulin sensitivity, and other hormones in ways we don't fully understand long-term.

What's the real bottom line?

Fernandes presents these peptides as proven optimization tools, but the science doesn't support that confidence. The human data is limited, and most studies focus on medical conditions, not healthy people seeking performance enhancement.

The Monday-through-Friday schedule seems arbitrary. There's no research suggesting this cycling approach is more effective or safer than daily use or longer breaks.

If you're considering peptides, work with a knowledgeable physician who can monitor for side effects and interactions. The DIY approach promoted in wellness spaces often skips important safety considerations that matter more than Instagram testimonials.
