Question 1

How do I reconstitute a peptide?

Accepted Answer

To reconstitute a peptide: 1) Draw bacteriostatic (BAC) water into a syringe. 2) Slowly inject water down the side of the peptide vial (never directly onto the powder). 3) Gently swirl — never shake. 4) Refrigerate. VialDex calculates exact BAC water volume and syringe doses for 50+ peptides.

Question 2

How much BAC water should I add to a peptide vial?

Accepted Answer

The amount of BAC water depends on your desired concentration. For example, adding 2ml to a 10mg vial gives 5mg/ml. VialDex automatically calculates the optimal water volume based on your vial size and preferred dose in syringe units. Common volumes range from 1ml to 5ml.

Question 3

How do I calculate syringe units for peptide dosing?

Accepted Answer

Syringe units depend on the concentration after reconstitution. Formula: Units = (Desired Dose ÷ Concentration) × 100. For a 10mg vial with 2ml BAC water (5mg/ml), 10 units = 0.5mg. VialDex calculates this automatically with visual syringe guides showing exactly where to draw.

Question 4

Is VialDex free to use?

Accepted Answer

Yes, VialDex is completely free. All calculators (reconstitution, blend, stack, nasal spray, BAC water), the peptide library, compatibility checker, TDEE calculator, and goal planner are available at no cost. No account required.

Question 5

Can I mix peptides in the same vial?

Accepted Answer

Some peptides can safely be mixed (e.g., BPC-157 + TB-500, Ipamorelin + CJC-1295). VialDex includes a compatibility checker that shows which peptides can share a vial. Always verify compatibility before mixing — some peptides have different pH requirements or may degrade each other.

Question 6

What is TDEE and how is it calculated?

Accepted Answer

TDEE (Total Daily Energy Expenditure) is the total calories you burn per day including BMR and activity. VialDex calculates TDEE using Mifflin-St Jeor or Katch-McArdle formulas, factored by your activity level. It also provides macro splits for protein, carbohydrates, and fat based on your goals.
