Expertise · Peptides

Peptide expert witness.

BPC-157, TB-500, growth hormone secretagogues and the compounded peptides now sold well ahead of any approval — reviewed by an endocrinologist who has written the clinical reference texts on these agents.

Peptide cases sit in a place most experts cannot reach: the agents have no FDA approval, no labelled dosing and often no human trials at all, yet they are prescribed, compounded and injected every day. A generalist expert has nothing to measure the care against. The opinion counsel actually needs is what a reasonable physician could have known about BPC-157 or ipamorelin at the moment of prescribing — and whether stepping past that evidence was defensible.

That is the literature I work in. I have published clinical reference texts on peptide therapeutics, maintain an active precision-medicine practice in which these requests arrive weekly, and review the primary evidence for each agent as it appears — which means my opinions rest on the state of knowledge at the time of care, not on hindsight.

Case Patterns

Where peptide matters arise

01

BPC-157 & TB-500

Compounds sold as "research chemicals" yet prescribed, injected in clinic or recommended by name — with no FDA approval, no established human dosing and an evidence base that is almost entirely preclinical. When a patient is harmed, the first question is what a prescriber could reasonably have believed about an agent that has never completed a human trial.

02

Growth hormone secretagogues

Ipamorelin, CJC-1295, sermorelin, tesamorelin and MK-677 prescribed for "optimization" without any workup of the growth hormone axis — no stimulation testing, no baseline IGF-1, no monitoring on therapy. The gap between what the marketing promised and what the chart documents is usually where these cases are decided.

03

Compounded peptide products

503A and 503B compounding of peptides that have no approved reference product — questions of potency, sterility, endotoxin contamination and whether the pharmacy could lawfully compound the substance at all. Injection-site infections, systemic reactions and product mislabelling each leave a distinct trail in the record.

04

"Research use only" supply chains

Peptides bought from gray-market vendors, resold or administered by med-spas, trainers and telehealth operations that never examined the patient. Tracing who supplied, who directed use and who owed a duty of care is often the threshold dispute — and the paperwork these operations keep, or fail to keep, is telling.

05

Consent & representation claims

Patients told a peptide was "safe", "natural" or "FDA-approved" when it was none of those things. I compare what was represented against the published evidence at the time — a literature I know closely, having written the clinical reference texts on these agents.

What the Record Shows

The questions I answer

  • What did the published evidence for this peptide actually support at the time it was prescribed or supplied?
  • Was the patient told the agent was unapproved and largely untested in humans — and is that consent documented?
  • Could the pharmacy lawfully compound this substance, and does the product record support potency and sterility?
  • Who in the supply chain — prescriber, med-spa, vendor — owed the duty of care, and what did each actually do?
  • Does the injury plausibly follow from the peptide, the dose and the timeline — or from something else in the chart?
