Overview
A B-vitamin + choline/inositol injection blend (9 components) for hair, skin, nails, and methylation support.
What It Does
Healthy Hair, Skin, Nails Blend; injectable B-complex (9 components) + choline/inositol for keratin synthesis, methylation, and skin support.
Nine B-vitamins support keratin synthesis, collagen production, NAD+ precursor loading, and cellular energy.

Reconstitution Calculator
Enter the vial amount and diluent volume to calculate concentration. If you already have a target amount, you can also convert it to liquid volume and syringe markings. This tool does not recommend a target amount.
Calculated concentration—Enter both values above.
Optional conversion
Enter a target amount you already have and select the syringe capacity.
Calculated draw—Enter concentration inputs and a target amount.
Mathematical reference only. The calculator does not determine an appropriate target amount. Syringe capacity only changes the maximum volume that fits.

Amount
Notes
Loading (Weeks 1–4)
2–3×/week
0.5–1 mL
Loading phase establishes B-vitamin saturation. Watch for niacin flush at higher per-injection volume.
Maintenance
Weekly
1 mL
Maintenance dose once vitamin levels are saturated. Hair/nail visible effects build 8–12 weeks.
Off
2 weeks
–
Optional break between 8–12 week maintenance blocks.
Cycle & Timing
8–12 weeks on / 2 weeks off, or ongoing.
Timing
3×/week IM/SubQ, anytime.
Population Considerations
Unisex blend, same protocol for men and women; follows its components. Avoid in pregnancy.
Handling & Stacking
Injection site
Upper outer glute or thigh.
Storage
Solution: refrigerate 36–46°F.
Use within 28 days.
Protect from light.
There's no real community potency figure for HHB; it's a B-complex solution, so sterility caps it near ~28–30 days refrigerated at 36–46°F, and keep it dark since riboflavin is light-sensitive.
Side effects
Niacin flush at higher per-injection doses. Possible injection-site stinging.
What to expect
Energy and methylation support within 1–2 weeks. Hair and nail effects build over 8–12 weeks.
Component allergies (B12, riboflavin, lecithin, choline, methionine, lidocaine) Hypothyroid medication, separate by 4 hours Severe hepatic impairment (choline metabolism) Pregnancy and lactation, specific compounding required Bleeding disorders or anticoagulants (relative), bruising risk
Warnings
Compounded products, composition varies; request the pharmacy’s COA B12 (cyanocobalamin) contains cobalt, allergy possible Methionine elevates homocysteine in some individuals L-Carnitine: TMAO conversion concern in CV disease (controversial, baseline lipids) Injection-site reactions common with phosphatidylcholine
Drug interactions
Warfarin: L-carnitine and choline blends can potentiate, monitor INR if combining Levothyroxine: separate by 4 hours, choline/B-vitamins affect absorption Anticoagulants / antiplatelets (DOACs, aspirin, clopidogrel): bruising risk with phosphatidylcholine Insulin / antidiabetics: B-complex may shift glucose, recheck log if dosing changes Methotrexate, trimethoprim, phenytoin: deplete folate / B12; coordinate with prescriber Lidocaine blends (LC526): avoid other caines same session, additive cardiac effects Stimulants / phentermine: additive CV load with high-dose lipotropics, monitor BP/HR
Fishy odor from choline/L-carnitine is normal, not allergic Inject slowly to reduce stinging Don’t use with warfarin without physician guidance (potentiation risk) Request exact ingredient list and concentrations from your compounder
