Dosing & Reconstitution Guide

A single practical dilution with accurate once-daily dosing, step by step

Standard / Gradual Approach (3 mL = ~1.67 mg/mL)

Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration ~1.67 mg/mL (1,667 mcg/mL).

Illustrative daily range: 100–250 mcg once daily, raised gradually over a 12-week course. This range is educational syringe-math, not an established clinical dose.

Easy measuring: At ~1.67 mg/mL, 1 unit ≈ 16.7 mcg on a U-100 syringe, so doses fall on easy-to-read marks (6–15 units).

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.

Wipe the stopper with an alcohol swab, then inject your bacteriostatic water slowly down the inside wall of the vial. Let it sit and gently swirl until dissolved — never shake. Store the mixed vial in the refrigerator and draw doses with an insulin syringe. Use the calculator above to turn any dose into syringe units. There is no single correct amount — more water simply spreads the same 1 mg of peptide across a larger volume, which makes small doses easier to measure accurately. 1 to 3 mL per vial is typical. Enter your chosen volume in the calculator above to see the resulting concentration and syringe units. On a U-100 insulin syringe, 100 units equal 1 mL, so 1 unit equals 0.01 mL.

Research Models and How Lipogenesis Is Actually Measured

Understanding how AOD-9604 has been studied clarifies both what the data can support and what a real antilipogenic investigation would require. The methodology falls into three tiers, and only the first touches lipogenesis directly. Ex vivo and in vitro fat-tissue work. The foundational studies examined lipolysis and lipogenesis in adipose tissue and isolated fat cells, measuring free-fatty-acid and glycerol release, fat oxidation, and — critically — the activity of lipogenic enzymes such as acetyl-CoA carboxylase.23 Enzyme-activity assays of this kind are the appropriate tool for an antilipogenic claim, and they are the source of the strongest evidence that a C-terminal domain peptide can suppress fat synthesis. A more complete modern program would add radiolabeled- or deuterium-tracer incorporation into fatty acids to quantify DNL flux, plus expression of ACC, FASN, SREBP-1c, and ChREBP under the peptide. Rodent models. The most methodologically informative animal work is the β3-AR knockout study, a clean genetic approach that isolated the receptor’s contribution by comparing knockout and wild-type mice under identical treatment.4 Obese Zucker rats and ob/ob mice provided body-weight, fat-mass, and substrate-oxidation readouts.15 These are genetically obese metabolic models, well suited to whole-body fat-balance questions but blunt instruments for isolating lipogenesis from lipolysis, since net fat change reflects both. Human trials. The clinical methodology was appropriate for an obesity drug — randomized, double-blind, placebo-controlled designs with weight and body-composition endpoints, plus dedicated safety and pharmacokinetic studies.610 A safety and tolerability study specifically characterized the peptide in humans.6 But none of these used lipogenesis endpoints. To answer this article’s question in humans would require a purpose-built study: stable-isotope measurement of de novo lipogenesis, adipose and hepatic lipogenic-gene expression, and controlled dosing — work that has never been done for AOD-9604. The methodological bottom line is that the antilipogenic evidence is strongest exactly where it is least generalizable (isolated rodent fat-tissue enzyme assays) and absent exactly where it would matter most (human DNL flux). Until that gap is filled, any statement that AOD-9604 “reduces lipogenesis in humans” is hypothesis, not finding. Terminology used across this literature — lipogenesis, lipolysis, DNL, ACC, FASN — is defined for reference in the site’s peptide and metabolism glossary.

Handling and Reconstitution in a Research Context

This section describes how NAD+ and its precursors are handled as laboratory materials, because handling directly affects the reproducibility and interpretability of research. It is not a how-to for self-administration and carries no implication that these compounds should be used to address Parkinson’s disease or any other condition outside a properly authorized study. The clinical trials discussed above used pharmaceutical-grade oral capsules manufactured and quality-controlled to trial standards, which is a very different thing from a lyophilized research vial. Oral precursors such as NR and NMN are the simplest to handle because they are supplied as capsules or powders intended for oral use, and the human Parkinson’s trials all used the oral route.1,2 Their main practical vulnerabilities are moisture and heat: NMN in particular is hygroscopic and can degrade if exposed to humidity, so powders are kept sealed, cool, and dry, and analytical labs verify content by high-performance liquid chromatography rather than trusting label claims. For any quantitative experiment, confirming compound identity and purity before use is a basic control, because degraded or mislabeled material is a common hidden source of irreproducibility. Lyophilized (freeze-dried) NAD+ intended for reconstitution introduces additional handling considerations that mirror those of injectable research peptides. Freeze-dried material is generally stored frozen, often at minus 20 degrees Celsius or colder, with colder storage preferred for long-term stability, and is protected from light and repeated freeze-thaw cycling, each of which can degrade sensitive dinucleotides. Reconstitution is typically performed with a sterile diluent added slowly down the inner wall of the vial rather than directly onto the powder, followed by gentle swirling rather than vigorous shaking, since mechanical agitation and foaming can damage the molecule; the vial is then allowed to dissolve fully before use. Once in solution, NAD+ is far less stable than in its dried state and is kept refrigerated at roughly 2 to 8 degrees Celsius and used within a limited window, on the order of days to a couple of weeks depending on conditions, because aqueous NAD+ hydrolyzes over time. Concentration is a function of the diluent volume added to a known mass; laboratories track this explicitly so that any downstream measurement is traceable to a defined concentration. General principles of this kind are covered in the site’s peptide reconstitution guide and the associated reconstitution calculator, which exist to support accurate laboratory record-keeping rather than to encourage use. Two broader points frame all of this. First, handling quality is a research-validity issue before it is anything else: an experiment run with degraded, contaminated, or inaccurately concentrated material produces uninterpretable data, which is one way that poorly controlled work generates the exaggerated claims this article is trying to counter. Second, none of these handling details change the compounds’ status. A carefully reconstituted NAD+ solution is still an unapproved research material, and meticulous technique does not convert a preclinical hypothesis into a validated Parkinson’s treatment. The site’s general research compound reference index catalogs handling parameters for many such materials on the same understanding: they are educational references for people working in controlled settings, not endorsements of use.

How to convert mcg to mg (and back)

Because the factor is exactly 1000, every conversion is a decimal-point move of three places — no calculator strictly required once you see the pattern: mcg → mg: divide by 1000, i.e. move the decimal point three places to the left. 500 mcg → 0.5 mg; 100 mcg → 0.1 mg; 1500 mcg → 1.5 mg. mg → mcg: multiply by 1000, i.e. move the decimal point three places to the right. 0.5 mg → 500 mcg; 2 mg → 2000 mcg; 1.25 mg → 1250 mcg. The tool above does the same move for you and trims trailing zeros, so you can paste in any value — whole or fractional — and read the exact counterpart.
