01 / RESEARCH SUMMARY

AOD-9604 Research Summary

AOD-9604 is a modified fragment of human growth hormone (amino acids 177–191). It was designed to keep growth hormone's fat-breaking (lipolytic) activity without affecting blood sugar, IGF-1 or tissue growth. Animal studies showed increased fat breakdown and reduced fat storage. Human trials found it well tolerated, but a larger phase 2b study did not show significant weight loss compared with placebo, and it has since been explored for cartilage and joint repair.

02 / WHY RESEARCHERS STUDY IT

Why AOD-9604 draws research interest

These are the areas researchers and the peptide community explore AOD-9604 for most often. They describe what is being studied — not proven benefits, approved uses, or promised results.

Fat metabolism

Designed to keep growth hormone's fat-breaking effect.

Joint & cartilage

Explored for cartilage repair and joint support.

No growth effects

Does not raise IGF-1 or affect blood sugar in studies.

Evidence ranges from early lab work to large clinical trials depending on the use — see the sections below for the data and sources.

03 / DOSING & RECONSTITUTION

Dosing & Reconstitution Guide

A single practical dilution with accurate dosing, step by step

Standard Approach (2 mL = 2.5 mg/mL)

  • Reconstitute: Add 2 mL bacteriostatic water to one 5 mg vial → final concentration 2.5 mg/mL (2,500 mcg/mL).
  • Typical range: 250–500 mcg 1x daily am · 5 on 2 off or daily, 8–12 weeks · fasted.
  • Easy measuring: At 2.5 mg/mL, 1 unit ≈ 25 mcg on a U-100 syringe, so doses read at 10–20 units — a 0.3 mL (30-unit) syringe makes them easier to read.
  • Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the mixed solution.

05 / STORAGE

Storage Instructions

Lyophilized (powder)

Store in the freezer at −20 °C (−4 °F) for long-term storage, or refrigerated at 2–8 °C for shorter periods. Keep dry, sealed and away from light. Let a frozen vial reach room temperature before opening to avoid condensation.

Reconstituted

Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 28 days. Do not freeze. Keep away from heat and direct light, and avoid repeated temperature swings. Swirl gently — never shake.

Reconstitution steps

  1. Wipe the vial stopper with an alcohol swab.
  2. Draw the BAC water and release it slowly down the inside wall of the vial.
  3. Swirl or roll gently until fully dissolved — don't shake.
  4. Label with the date and concentration and refrigerate.

06 / RESEARCH FINDINGS

What Research Shows

Human research

  • Lipid metabolism and body-weight outcomes have been investigated.
  • The proposed metabolic effects of a growth-hormone fragment are not proof of weight-loss efficacy.
Research context

Human investigation does not establish a clinically effective research-vial weight-loss regimen.

07 / MOLECULAR BIOLOGY

Mechanism of Action

Investigational mechanism

Growth hormone fragment and lipid metabolism

A modified C-terminal growth hormone fragment investigated for effects on lipid metabolism. The proposed lipolytic activity does not establish an effective human weight-loss treatment or a settled clinical mechanism.

Adamantane & the blood–brain barrier

Chemically attaching an adamantane group to a peptide can increase its lipid (fat) solubility. Researchers hypothesize that this modification may help certain compounds cross the tightly regulated blood–brain barrier. The effect depends on the specific modified molecule; greater lipid solubility alone does not establish brain delivery or clinical benefit. This does not apply automatically to the unmodified peptide and is not a reconstitution additive.

08 / LIFESTYLE FACTORS

Lifestyle Factors

  • Exercise: these compounds work alongside, not instead of, regular training — especially zone 2 cardio.
  • Sleep and circadian rhythm: keep a consistent sleep schedule.
  • Nutrition: whole-food diet with adequate protein; avoid chronic overeating.
  • Track bloodwork (glucose, lipids, liver markers) before and during longer cycles.

09 / BENEFITS & SIDE EFFECTS

Potential Benefits & Side Effects

Potential Benefits

  • Improved energy and exercise capacity
  • Better insulin sensitivity and metabolic markers
  • Support for mitochondrial function
  • Potential fat-loss support (5-Amino-1MQ, AOD-9604, SLU-PP-332)

Side Effects

  • Injection-site irritation
  • NAD+: flushing, chest tightness or nausea if pushed too fast
  • Fatigue or restlessness early in a cycle
  • GI discomfort with oral compounds

Studies & references

11 / SAFETY

Safety considerations

  • Verify the active identity, lot number, and matching certificate of analysis. Testing does not by itself establish sterility or suitability for human use.
  • Follow documented product-specific storage and preparation requirements; stability and diluent compatibility depend on the formulation.
  • Research powders are not interchangeable with prescription formulations. Do not infer an injection or nasal protocol from a concentration calculation.
  • For medical care, pregnancy, existing conditions, or medication interactions, consult a qualified healthcare professional.
