Injection
Injection equipment for peptide research protocols. Community sources cite 31G ultra-fine insulin syringes as the default for sub-Q dosing, with 0.3 cc volumes preferred for protocols dosing under 50 units (each gradation marks 1 unit at 0.3 cc vs 2 units at 1 cc). The reusable peptide pen is the format users transition to once a multi-week protocol becomes routine.
Reusable Peptide Pen Injector (80-unit, 3mL Cartridge)
Dial-a-dose reusable pen with 2× 3mL refillable cartridges and storage case. 80-unit max dose covers any peptide protocol. What most GLP-1 users transition to once they're tired of insulin syringes.

BD Ultra-Fine 31G 0.3cc 5/16" Insulin Syringes (Box of 90)
0.3cc 31G syringes — each gradation marks 1 unit (vs 2 units on 1cc), making sub-50-unit peptide doses accurate. BD Ultra-Fine is the most widely-cited brand in peptide community sources.

BD Ultra-Fine 31G 1cc 5/16" Insulin Syringes (Box of 90)
1cc holds up to 100 units — broadest peptide-use coverage. BD's most-reviewed insulin syringe (1.6K reviews, 4.6★). Each gradation = 2 units, so prefer the 0.3cc for sub-50-unit precision dosing.

U-100 31G 1ml 5/16" Syringes (Box of 100)
Amazon's Overall Pick for peptide injection at $0.23/syringe. Same 31G ultra-fine gauge as BD at ~40% lower cost-per-unit — the practical pick when you're going through 50+/month on a multi-peptide protocol.

Brandzig 1mL Luer-Lock Syringes with Needle
1mL luer-lock syringe with a fitted needle — the standard draw-and-inject size for reconstituted doses. The luer lock lets you swap to a separate draw needle for the vial and a thin needle to inject.

Disposable 30G Injection Needles (Individually Wrapped)
30-gauge individually-wrapped needles — the thin size for the subcutaneous injection itself, after you've drawn your dose with a larger needle. Standard for comfortable sub-Q peptide injections.

Disposable Draw Needles (Individually Wrapped)
Individually-wrapped larger-gauge needles for drawing reconstituted solution out of the vial. A bigger draw needle pulls faster from high-volume vials like NAD+ (1000mg) or glutathione (1500mg) — draw with this, then switch to a thin 30G needle to inject.

What's the difference between 0.3 cc and 1 cc insulin syringes?+
On a 0.3 cc (30-unit) syringe, each gradation marks 1 unit. On a 1 cc (100-unit) syringe, each gradation marks 2 units. Community sources cite the 0.3 cc as the more accurate choice for peptide doses under 30 units; 1 cc covers larger doses or fewer-injection schedules but with coarser measurement.
Why a reusable pen instead of syringes?+
Reusable insulin pens accept 3 mL refillable cartridges and dial doses by unit, similar in form factor to insulin therapy devices. Community sources cite the pen format as the format users transition to once a peptide protocol becomes routine — convenience and dose-dialing consistency are the most-mentioned drivers.
Where can sharps containers be disposed of?+
Most US states require sharps to be brought to a designated drop-off site (often pharmacies, fire stations, or municipal hazardous-waste facilities) rather than household trash. The specific rules vary by state and county. The FDA-cleared puncture-proof containers in this category accept disposal at almost every drop-off point that accepts personal-use sharps.
