Dosing, cycle & timing
- Conservative 250-500 mg per injection, 3-5x/week (25-50 units per injection)
- Standard 500-1000 mg per injection, 3-6x/week (50-100 units per injection)
- Aggressive 1000 mg per injection once daily (100 units per injection) if tolerated
- Cycle length 8-16 weeks
- Best timing Pre-workout on training days or morning.
Support / expected effects
- Fatty-acid transport/oxidation support.
- May improve endurance in some.
- Often paired with GLP-1 class for energy/body comp.
Side effects / tolerability
- Site soreness (IM).
- Fishy odor/sweat in some.
- Mild nausea at high dose.
Practical tips
- If odor occurs, reduce dose/frequency.
- Smaller volumes per site reduce soreness.
- Training-day use gives best ROI.
Storage
Typically refrigerated after opening; many use within ~60-90 days if sterile.

FAQ
What is L-Carnitine explored for?
Fatty-acid transport/oxidation support. May improve endurance in some. Often paired with GLP-1 class for energy/body comp.
How is L-Carnitine prepared?
L-Carnitine is premixed. Do not add bacteriostatic water; calculate the injection volume from the labeled concentration and the planned milligram dose.
How do syringe units apply to L-Carnitine?
Units only apply after concentration and injection volume are known. For the listed 1000 mg/mL example, 250 mg is 0.25 mL, which is 25 units on a U-100 syringe.
