02 — Researched for

What is being studied.

Growth hormone deficiency; GH axis stimulation in adults.

04 — What is claimed but not shown

Claimed, not demonstrated.

Reversal of age-related decline, fat loss and improved sleep in healthy adults.

05 — Known risks

Documented risks.

Injection-site reactions, flushing, headache; IGF-1-related long-term concerns in non-deficient adults.

07 — Questions for your physician

Six questions worth printing.

  1. 01What is your primary board certification, and in what year did you obtain it?
  2. 02Is this peptide approved for what you are prescribing it for — and if not, what is the legal basis on which you are supplying it?
  3. 03Which human trials support this use, and what were their size and duration?
  4. 04Where does the product come from, and can you show me a certificate of analysis for this batch?
  5. 05What outcome will we measure, when, and what happens if it does not improve?
  6. 06What is the total cost for the first three months, in writing?
