Identify the claim behind the photograph
Ask what the advertisement wants you to conclude. A smaller waist, more visible muscle, or a different facial appearance may imply a treatment benefit even when the caption avoids making a direct promise. “Real patient” answers a question about the image’s subject; it does not answer whether the treatment caused the outcome.
The FTC’s health-products guidance explains that testimonials still need scientific support for their underlying health claims. A person can honestly describe an experience without that experience establishing what a product will do for others. You do not have to accuse the person of dishonesty to recognize that limit.
Check whether the comparison is interpretable
Look for dates, a stated interval, and a clear description of the treatment used. Are the pictures comparable in posture, lighting, distance, clothing, and camera angle? If those details differ, the apparent size of a change becomes harder to interpret. A photograph without its context should not be treated as a measurement.
Ask whether the person used sermorelin alone, a blend, another medication, or a broader program. A transformation attributed to “peptide therapy” may not identify the actual intervention. Likewise, a photo labeled “after” does not show whether it was taken immediately after treatment, months later, or at the person’s preferred moment. Missing information is a reason to narrow the conclusion, rather than fill the gaps with assumptions.
Account for everything else that changed
A person may change eating habits, training, sleep routines, or other treatments during the same period. Those changes matter when someone attributes the final photograph to one prescription. Even a carefully dated pair of images cannot separate the contributions of several simultaneous changes.
Ask for research that compares relevant groups and measures the outcome being claimed. A photograph does not quantify muscle strength, visceral fat, bone density, or long-term health. It also cannot establish that any weight lost was maintained. Our weight-loss evidence guide addresses the difference between a body-composition claim and an established clinical benefit. The question is what the evidence can measure, not how striking the picture appears.
Ask who is missing from the gallery
A gallery presents selected examples. Without knowing how many people started, stopped, saw no change, or declined photographs, you cannot calculate a typical result from it. Ten favorable images could come from ten customers or a much larger group; the display alone does not supply that denominator.
The FTC also cautions that a vague “results not typical” disclaimer does not adequately resolve a misleading impression of expected results. Look for clear information about what consumers can generally expect and the evidence behind it. An influencer’s discount code or sponsorship disclosure helps you understand a commercial relationship, but disclosure does not transform a testimonial into a controlled study.
Use photographs as a starting point for questions
If an image interests you, bring the specific claim to the clinician. Ask whether the treatment and patient population match the available research, what benefit could reasonably be assessed in your case, and what would count as no meaningful improvement. Discuss harms and burdens as well as visible changes.
For your own follow-up, agree on the relevant outcomes before treatment rather than choosing whichever later measurement looks most favorable. Photos may be part of a record if you and the clinician find them useful, but they should not displace symptom review or appropriate testing. A treatment decision needs more than a compelling image and a timeline that promises a similar transformation.
