❄️ Unmixed
Lyophilized Peptide
🌡️ -20°C (Freezer)
- Short-term (Weeks): Can safely remain at room temperature away from direct sunlight during shipping or brief storage.
- Long-term (Years): Store in the freezer below -20°C to maintain 100% purity for up to 36 months.
- Keep the vial sealed. Moisture is the enemy of raw lyophilized powder.
💧 Liquid Solution
Reconstituted Peptide
🌡️ 2°C to 8°C (Fridge)
- Shelf Life: Once mixed with BAC water, the peptide must be used within 20 to 30 days.
- Storage: Must be kept in the refrigerator at all times when not in active use.
- Avoid leaving it out on the counter. Keep away from intense light and extreme temperature fluctuations.
DO NOT FREEZE MIXED PEPTIDES
Never place a reconstituted (liquid) peptide vial in the freezer. The formation of ice crystals will physically expand and shatter the fragile amino acid bonds, permanently destroying the compound’s effectiveness.
Frequently Asked Questions
Everything you need to know for safe and effective peptide handling.
What type of water is best for reconstitution?
Bacteriostatic Water (BAC Water) is highly recommended. It contains 0.9% benzyl alcohol, which prevents bacterial growth and extends the shelf life of your mixed peptide to 20-30 days when refrigerated. Sterile water can be used, but the mixture must be discarded within 24-48 hours.
Why shouldn’t I shake the vial to mix it faster?
Peptide chains are comprised of delicate amino acid bonds. Shaking the vial vigorously introduces extreme physical stress and air bubbles, which can break these bonds and permanently destroy the active compound. Always swirl gently.
How much BAC water should I add to a 5mg vial?
The amount of water determines your concentration, not the total dose. Typically, researchers add 1ml or 2ml of BAC water to a 5mg vial. Adding 2ml makes the math easier for micro-dosing (e.g., 2ml water + 5mg powder = 2.5mg per ml).
My peptide looks cloudy after mixing. Is it ruined?
No, it is not ruined. Some peptides are slightly more hydrophobic and take longer to dissolve. Do not shake it. Simply place the cloudy vial in the refrigerator for 15-30 minutes; it will naturally dissolve into a crystal-clear liquid.
Can I freeze the peptide after I’ve mixed it with water?
Absolutely NOT. Once a peptide is reconstituted into a liquid, freezing it will cause ice crystals to form. These expanding crystals act like microscopic knives, shattering the peptide molecules and rendering the solution useless.
Does unmixed powder need to be refrigerated during shipping?
Lyophilized (freeze-dried) powder is remarkably stable. It can survive at room temperature for several weeks without degradation, making standard shipping perfectly safe. However, upon arrival, it should be placed in the freezer for long-term storage.
Are insulin syringes required for this process?
Yes, standard 1ml (100-unit) insulin syringes are the industry standard. They allow for highly precise measurements of tiny liquid volumes (micro-dosing) and have fine needles that minimize damage to the vial’s rubber stopper.
How do I equalize the pressure in the BAC water bottle?
Before drawing BAC water, pull your syringe plunger back to draw air equal to the amount of water you need (e.g., 1ml of air). Inject this air into the BAC water bottle. This prevents a vacuum from forming, making it much easier to pull the liquid out smoothly.
