Among the findings:17 76% of men were more satisfied with their lovemaking and duration of lovemaking 83% said vaginal insertion was easier 65% found it was easier to orgasm 56% found orgasms to be more pleasurable 65% found that lovemaking was more pleasurable 71% found that the partners overall experience was more pleasurable 76% were more at ease about initiating lovemaking For all that, a question remains as to PT-141s overall utility as an ED remedy compared with PDE5 inhibitors

This may be due to copper's ability to enhance the expression of metalloproteinases (MMPs).16 MMPs normally regulate the degradation of collagen, and a specific one, MMP-1, may be responsible for the initiation of collagen fragmentation.17 Supporting this, a 2024 study noted that elevated MMP-1 levels appear to contribute to aging skin and that higher MMP-1 levels in mice led to:18 The loss and fragmentation of dermal collagen fibrils Contracted fibroblast morphology Reduced collagen production Increased expression of pro-inflammatory mediators Additionally, a 2016 study found that GHK-Cu significantly increased gene expression of MMP-1 and MMP-2 at the lowest concentration, which the studys authors considered to be one of the reasons the peptide was able to increase collagen and elastin production.19 So, what this could ultimately mean is that using too much GHK-Cu (or other copper peptides) may in theory increase the skins MMP-1 concentration above the levels involved in healthy collagen production, taking it into the collagen fragmentation and breakdown territory seen in older skin with naturally higher MMP-1 levels
