BPC-157 shows unusual stability in gastric acid, which is biologically consistent with its origin as a fragment of a gastric protein
And any further mixing is done with a spatula

A Dermatologists Take on the Copper Peptide (GHK-Cu) Trend

Red Flags in Before and After Photos Different lighting: Bathroom fluorescent light vs golden-hour window light can make anyone's skin look dramatically different regardless of what product was used Different camera distance or angle: Even a few inches closer creates apparent texture smoothing "Results in 1 week": Anyone showing dramatic wrinkle reversal in one week is using either injectable delivery, a film-forming agent for temporary tightening, or misleading photography No defined timeframe: Legitimate results specify exactly how many weeks of use are shown No single variable: If the person changed multiple products during the documented period, you cannot attribute results to GHK-Cu specifically Green Flags in Credible Documentation Identical lighting in both photos (same room, same time of day, same source) 3D imaging or VISIA documentation the gold standard used in clinical studies Specified timeline with consistent single-product use Progressive documentation (4-week, 8-week, 12-week) rather than a single dramatic comparison Honest acknowledgment that results vary and are gradual The clinical studies that produced GHK-Cu's most impressive numbers 55.8% wrinkle volume reduction used VISIA 3D profilometry imaging systems that eliminate all lighting and angle variables entirely
