Dosing & Reconstitution Guide

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

Standard / Gradual Approach (3 mL = ~3.33 mg/mL)

Reconstitute: Add 3.0 mL bacteriostatic water to one 10 mg vial → final concentration ~3.33 mg/mL (3,333 mcg/mL).

Typical daily range: 50–200 mcg once daily, raised gradually over an 8–16 week course.

Easy measuring: At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg on a U-100 syringe. Because doses are very small, a 30- or 50-unit insulin syringe is recommended for the best low-volume accuracy.

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 10 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. The calculator above converts your draw volume into these units automatically so you can measure without doing the math by hand. Keep the reconstituted vial refrigerated at roughly 2 to 8 degrees Celsius, away from light, and avoid freezing it. Reconstituted research peptides are generally used within a few weeks. Always follow the specific guidance supplied with your product. Divide the vial strength of 10 mg by the amount you use per injection.

Did the impressive cognition study use Sermorelin?

No — and this is a crucial distinction. The randomized controlled trial that found improved executive function in older adults used tesamorelin, a stabilized, longer-acting GHRH analog dosed at 1 mg daily, not Sermorelin.5 The two share the GHRH mechanism but differ in stability and duration of action. The result supports the idea that GHRH-receptor stimulation may benefit cognition; it does not establish that Sermorelin specifically reproduces that effect.

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 reference

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.
