HGH Dosage & Reconstitution Calculator

HGH Dosage & Reconstitution Calculator 🧬

Calculate HGH vial usage, total IU needed for your cycle, reconstitution volumes, and syringe draw amounts. (Optional) Browse our HGH products. Browse matching HGH products (optional).

How Much I Need?

This tool estimates the total HGH (IU) needed for your cycle and recommends how many vials, packages, or pens to order. Select dose unit, dose per injection, injections per week, and cycle length — the calculator returns total IU required, recommended vial/pen counts, and step‑by‑step math for verification.

HGH Reconstitution & Syringe Guide 💧

This tool calculates reconstitution volumes and syringe draw amounts for HGH. Enter vial strength and bacteriostatic water volume, then set your desired IU dose — results show concentration (IU/mL), IU per syringe unit, and exact draw per injection. A built-in mg ⇄ IU converter (default 1 mg ≈ 3 IU, editable) is included to show how conversions affect dosing and vial usage.

HGH – Human Growth Hormone 🧬

Human growth hormone (HGH, somatropin) is a peptide‑class hormone produced by the pituitary that regulates growth, metabolism, body composition, tissue repair, and recovery. Recombinant HGH is used in clinical medicine for growth disorders, adult growth‑hormone deficiency, and select wasting conditions; in research settings it’s used to study metabolism, muscle physiology, and endocrine signaling. Because somatropin is target‑specific and smaller than many hormones, precise dosing and handling are essential.

How the calculators work

Quick conversion & concentration

Standard conversion (editable): 1 mg ≈ 3 IU for somatropin (recombinant HGH). Convert mass to IU using IU = mg × (IU per mg). Convert IU to mass using mg = IU ÷ (IU per mg).
Concentration (IU/mL) = total HGH (IU) ÷ total solvent (mL). Example: 10 IU in 2 mL → 5 IU/mL.

Volume to draw

Volume (mL) = desired dose (IU) ÷ concentration (IU/mL). Example: 2 IU ÷ 5 IU/mL = 0.4 mL (40 units on a 100‑unit syringe). 💉

Bacteriostatic water, sterile water, or normal saline (NaCl) 💧

• Sterile water for injection (WFI): pure water, no salts or preservatives; hypotonic. Intended for immediate, single‑use reconstitution.
• Bacteriostatic water: sterile water + preservative (usually 0.9% benzyl alcohol); allows multiple withdrawals and refrigerated storage (commonly 14–28 days per manufacturer). Not suitable for some populations or routes (e.g., neonates, pregnant women, intrathecal). ⚖️
• Normal saline (0.9% NaCl): isotonic sodium chloride solution; used for IV infusions, flushing, and some reconstitutions where isotonicity is required. Not the same as sterile water—contains salt. Which to use: follow the peptide manufacturer’s instructions; use bacteriostatic water for multi‑dose regimens when appropriate, sterile water or saline when single‑use or indicated. 🩺

Practical reconstitution notes

Preparation & technique

Work on a clean surface; wash hands and disinfect vial septa with 70% isopropyl alcohol. Add solvent slowly down the vial wall (don’t blast powder); swirl gently—do not shake vigorously (vigorous shaking can denature HGH). Inspect for cloudiness/particulates; discard if present.

Conversions & calculations

If vial is labeled in mg, convert mg → IU using the mg⇄IU converter (default 1 mg = 3 IU), then calculate IU/mL and compute mL to draw using formulas above. For syringe units: 1 mL = 100 units (so 0.5 mL = 50 units).

Mixing & measuring

When mixing products in one syringe, recalculate concentrations and confirm compatibility—mixing without recalculation increases dosing error risk. ⚠️ If required draws are below syringe resolution, increase solvent volume (lower concentration) to make measuring easier, and recalc vial usage.

Dosing examples + common scenarios

• 2 mg vial, converter 1 mg = 3 IU → vial = 6 IU. Add 1 mL → 6 IU ÷ 1 mL = 6 IU/mL. A 1 IU dose = 0.1667 mL (16.7 units).
• 10 IU vial, add 2 mL → 10 IU ÷ 2 mL = 5 IU/mL. A 2 IU dose = 0.4 mL (40 units).
• To simplify very small doses, increase solvent volume and recalc concentration and total vials needed.

Storage & handling ❄️

Short- and Long-Term Storage

• Lyophilized (dry) HGH — short term: store at 2–8°C (refrigerator) for days to a few months if manufacturer permits.
• Lyophilized — long term: store at −20°C (freezer). For archival or highly sensitive lots, −80°C is ideal.
• Reconstituted solutions (bacteriostatic water): refrigerate at 2–8°C, use within manufacturer guidance (commonly 14–28 days).
• Reconstituted (sterile water, no preservative): plan for single‑use or immediate short‑term use; refrigerate and discard within 24–72 hours unless manufacturer states otherwise.

Best practices

Avoid freeze–thaw cycles — aliquot reconstituted or diluted HGH into single‑use vials/syringes. Use a dedicated refrigerator/freezer (avoid frost‑free freezers due to cyclic warming). Protect from light and moisture; store vials in opaque boxes or wrap in foil; use desiccants for humidity control. Thaw sealed frozen vials at room temperature before opening (to avoid condensation). Thaw aliquots rapidly and use immediately. Use aseptic technique: sterile needles/syringes, disinfect septa, avoid touching needle tips. Discard any vial with discoloration, cloudiness, or particulates. 🧼

Containers, Labeling, and Transport

• Use clean glass or recommended high‑quality polypropylene vials (some plastics adsorb proteins like HGH).
• Label vials clearly with product name, IU or mg and converted IU/mL concentration, total volume, reconstitution date/time, and expiry. Keep an inventory/log with lot numbers and storage temps. 🏷️
• For transport, use insulated containers with cold packs (4°C) or dry ice (−20/−80°C shipments), minimizing transit time.

Troubleshooting & tips

If HGH dissolves slowly, warm the sealed vial gently by rolling it between your hands or place the sealed vial in warm water (not hot); never heat the vial directly or shake it violently (heat/shaking can denature HGH). If particulates or clumps remain after gentle mixing, contact the supplier and do not use the product. Increase the reconstitution volume to make measuring small doses easier, and remember to recalculate the concentration and vial count accordingly. Keep a dosing log that records the date, time, vial used, concentration, and units drawn for full traceability.
