AOD-9604 vs NAD+
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
AOD-9604
AOD-9604 is a modified fragment of human growth hormone (HGH fragment 176-191). It was developed to have the fat-reducing effects of growth hormone without the adverse effects on blood sugar or growth.
Full details →NAD+
Nicotinamide Adenine Dinucleotide (NAD+) is an essential coenzyme found in every living cell. It plays a central role in energy metabolism, DNA repair, gene expression, and cellular signaling. NAD+ levels naturally decline with age, and restoring them has become a major focus of longevity research. Injectable NAD+ bypasses the GI tract for higher bioavailability compared to oral precursors like NMN or NR.

| Aspect | AOD-9604 | NAD+ |
|---|---|---|
| Mechanism | Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat accumulation) without affecting blood sugar or growth. Works specifically on adipose tissue through a mechanism independent of GH receptors. | NAD+ is a critical substrate for sirtuins (SIRT1-7), a family of enzymes involved in DNA repair, inflammation regulation, and mitochondrial function. It also serves as a coenzyme for PARP enzymes (involved in DNA damage repair) and CD38 (involved in immune cell signaling). By directly replenishing cellular NAD+ pools, injectable NAD+ supports mitochondrial electron transport chain function, enhances ATP production, and activates longevity-associated pathways. |
| Typical Dosage | Research dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg. | Subcutaneous injection, typically 2–3 times per week. Start low and escalate: Twice per week protocol: Week 1: 20 mg (0.1 ml), Week 2: 40 mg (0.2 ml), Week 3+: 120 mg maintenance (0.6 ml). Three times per week protocol (e.g. Mon/Wed/Fri): Week 1: 20 mg (0.1 ml), Week 2: 40 mg (0.2 ml), Week 3+: 80 mg maintenance (0.4 ml). Volumes above assume 200 mg/ml concentration (100 mg vial reconstituted with 0.5 ml BAC water). Inject slowly — rapid administration increases flushing and nausea. Avoid back-to-back injection days. IV infusion (clinical setting): 250–750 mg per session over 2–4 hours. |
| Administration | Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects. | Subcutaneous injection is the most practical route for self-administration. Inject slowly — rapid administration increases side effects (flushing, chest tightness, nausea). Some users split larger doses across multiple daily injections to improve tolerance. IV infusions provide the highest bioavailability but require a clinical setting. Store reconstituted NAD+ refrigerated and protect from light. NAD+ solutions are pH-sensitive; use bacteriostatic water for reconstitution. |
| Side Effects | Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH. | Flushing and warmth (very common, especially at higher doses or fast injection rates). Nausea and mild GI discomfort. Chest tightness or pressure during injection (usually transient). Injection site pain or redness. Headache. These side effects are typically dose-dependent and diminish with slower administration and repeated use. |
