Cortagen

Short brain-tissue-derived bioregulator peptide.

Yes — Cortagen is a peptide, meaning a short chain of amino acids. Peptides are usually handled as a freeze-dried powder that is mixed with bacteriostatic water before use.

No. Cortagen is not an anabolic steroid. Steroids are fat-soluble hormones built on a four-ring cholesterol backbone; peptides are chains of amino acids and work by signalling to receptors rather than acting directly on DNA in the same way.

LYOPHILIZED (unopened): store at 2-8°C (fridge) or -20°C (freezer) long-term. Protect from light.

Peptide Wizard lets you record each entry, keep a vial ledger so you know what's left, and chart your own metrics over time. It is a logbook and reference only — it does not calculate or recommend doses.

As a general convention a reconstituted vial is treated as good for around 28 days refrigerated at 2-8 C, roughly 60 days frozen, and only a few days at room temperature. That figure comes from standard practice for preserved multi-dose vials rather than a test on any single compound, so the instructions supplied with your own vial take precedence. There is a full storage guide at peptidewizard.app/guides/storage/.

Cortagen is generally handled as subq. Sealed powder is normally kept refrigerated or frozen and mixed with bacteriostatic water when it is going to be used.

Cortagen is a chain of amino acids that signals to receptors. Anabolic steroids are fat-soluble hormones built on a cholesterol backbone and behave completely differently in the body. Neither this page nor the app provides guidance on using either.

Divide what you paid for the vial by the number of doses in it. A 10 mg vial contains 10 mg, or 10000 mcg, so the number of doses depends entirely on the amount you use. The calculator on this page does the arithmetic, including the doses you lose if the vial expires first.

Per milligram, usually yes. Per dose you actually use, not always — a larger vial you cannot finish inside its stability window can work out more expensive than a smaller one you do finish, because the leftover doses were still paid for.

Because a reconstituted vial has a limited usable window, commonly quoted as around 28 days refrigerated. Doses still in the vial when that window closes are wasted, so the honest figure is the price divided by the doses you reach in time.

Commonly quoted at around 30 days when kept refrigerated. Frozen extends that considerably, provided you freeze it once rather than thawing and refreezing. At room temperature you are counting in days. Purity, buffers and preservatives all change the answer, so the information supplied with your own vial takes precedence.

Kept in the fridge at roughly 2-8 C, a reconstituted vial is commonly treated as good for around 30 days. Sealed powder keeps far longer cold. Freezing it once extends the window further still. Purity, buffers and preservatives all shift the real figure, so treat this as a general convention rather than a measured result for this specific compound.

A short spell at room temperature — think hours, or while it warms up before use or is in the post — is generally tolerated, and sealed powder is more forgiving than a mixed vial. Heat is the single biggest cause of degradation, so the warmer it is the shorter the safe window, and days left warm is a different matter to a brief excursion. Keep it away from direct light too.

Once reconstituted, refrigeration is the normal recommendation, and heat is by far the biggest cause of degradation. Sealed lyophilized powder is more tolerant but still keeps best cold and away from light.

Freezing once is generally considered fine and extends the usable window. Repeated freeze-thaw cycles are what cause damage, so splitting into smaller amounts before freezing means you only thaw what you need.

Write the date you mixed it on the vial, or record it in a tracking app. Without that date there is no reliable way to know, which is the most common reason a vial gets used past its window or thrown away early.
