Complete Peptide Reconstitution Guide: BAC Water, Mixing & Storage Best Practices

Why Proper Reconstitution Matters

Your reconstitution technique shapes the validity of your data. Degradation, aggregation, and contamination all start here, and any one of them kills experimental reproducibility.

BAC Water vs Sterile Water
Property BAC Water Sterile Water
Antimicrobial Yes — 0.9% benzyl alcohol No
Multi-use vial Yes — safe for multiple draws Single use only
Post-reconstitution storage Up to 28 days at 2–8°C Use immediately
pH ~5.7 (slightly acidic) ~7.0 (neutral)

FenaLife supplies BAC Water 10ml specifically for research peptide reconstitution.

⚠️ The #1 Reconstitution Mistake
Injecting BAC water directly onto the lyophilized peptide pellet. The turbulence and mechanical force disrupts peptide bonds and causes aggregation. Always direct water against the inside wall of the vial.
Complete Reconstitution Protocol
1
Calculate target concentration first
Decide your target mg/mL before touching anything. See the concentration table below.
2
Allow vial to reach room temperature
Wait 10–15 minutes after removing from freezer to prevent moisture condensation.
3
Disinfect vial tops with alcohol swab
Wipe rubber septum of both vials. Allow to dry fully.
4
Draw up calculated BAC water volume
Use a sterile syringe. Draw slowly to avoid bubbles.
5
Inject BAC water SLOWLY down the inside vial wall
Angle needle so water runs gently down the wall — never shoot directly onto the powder pellet.
6
Swirl gently in circular motion — do not shake
Gentle rotation dissolves the powder. Shaking causes aggregation.
7
Check for complete dissolution
Solution should be clear and colourless. Continue gentle swirling if particles remain.
8
Label immediately
Peptide name · Concentration · Reconstitution date · Expiry (28 days) · Storage: 2–8°C
Concentration Reference — 10mg Vial
BAC Water Added Concentration Use Case
1.0mL 10 mg/mL (10,000 mcg/mL) Standard high-concentration
2.0mL 5 mg/mL (5,000 mcg/mL) Common research concentration
5.0mL 2 mg/mL (2,000 mcg/mL) Lower concentration studies
10.0mL 1 mg/mL (1,000 mcg/mL) Dilute concentration research

Formula: Concentration (mg/mL) = Mass (mg) ÷ Volume (mL). Use FenaLife’s Peptide Calculator to run this automatically.

Storage Quick Reference
Stage Temperature Duration
Lyophilized (most peptides) −20°C Long-term stable
Lyophilized (IGF-1 LR3) −80°C preferred Long-term stable
Reconstituted in BAC water 2–8°C Up to 28 days
Special Reconstitution Notes by Peptide
Peptide Special Note
IGF-1 LR3 Often requires initial reconstitution in 0.1% acetic acid before diluting
GHK-Cu Sensitive to oxidation — minimize air exposure, use promptly
NAD+ pH and hydrolysis sensitive — use freshly made solutions
Most other peptides Standard BAC water reconstitution as described above
