Ovagen Reconstitution Calculator

Your calculator only works with mass (mg). For a tripeptide this small, the same mg dose contains many more molecules than a larger peptide. For Ovagen, 1 mg corresponds to approximately 2.66 µmol (using the free acid MW 375.37). If your research protocol is based on molar concentrations (e.g., a cell culture study at 0.05 ng/mL), entering the equivalent mass into the calculator will not automatically give you the correct molarity. You must manually calculate the molar concentration of your solution and adjust the entered mg dose accordingly.

The calculator’s colour coding is driven purely by mathematical neatness. The standard Ovagen protocol calls for adding 3.0 mL of BAC water to a 20 mg vial, yielding a concentration of approximately 6.67 mg/mL and making syringe calculations simple for the recommended 800–2000 mcg (0.8–2 mg) daily dose range. If the 3 mL option results in unit values that are not perfect multiples of 5 on your chosen syringe, the calculator may demote it to “Good” or “Usable”. For Ovagen, you should prioritise the empirically validated protocol and override the calculator’s colour‑coded suggestion.

As an acidic tripeptide, Ovagen has a high overall polarity. While it is generally soluble in water, the acidity of the molecule means that solubility can be further enhanced by using a volatile basic buffer. Standard peptide solubility guidelines recommend, for peptides containing many acidic amino acids (such as Asp and Glu), using a 1‑10% aqueous ammonia solution to aid dissolution. If your calculator‑suggested concentration leaves the powder only partially dissolved or the solution appears cloudy, you should consider adding a small amount of 1‑10% ammonium hydroxide, not just more BAC water. The calculator does not warn about the need for a basic solvent for this specific peptide.

Your calculator is a neutral dilution tool; it does not know which research model you are using. In a kidney cell culture study, the effective concentration of Ovagen was as low as 0.05 ng/mL. In a study on ovarian function, the dose range might be 800‑2000 mcg (0.8‑2 mg) daily. In HIV‑1 protease inhibition research, the tripeptide EDL itself is structurally documented as binding an enzymatic active site, illustrating sequence‑specific bioactivity that is not dose‑dependent in a simple linear way. The calculator will correctly reconstitute any mass you enter, but you must first determine the correct dose for your specific research domain from the literature.

The 28‑day chemical stability window is longer than the 25‑day usage period, so from a chemical degradation standpoint, the later doses should still be potent. However, repeated puncturing of the vial over 25 days significantly increases the risk of microbial contamination, even with the benzyl alcohol preservative in BAC water. General sterility guidelines for multi‑dose vials recommend discarding the vial after 28 days regardless of remaining volume. For a 25‑day protocol that aligns with this window, you must use rigorous sterile technique: always wipe the rubber septum with 70% alcohol before each draw and visually inspect the solution for turbidity or particles. The calculator’s “Doses per vial” number is a practical guide in this case, but it requires strict adherence to aseptic handling.
