Crystagen dosage
Crystagen is taken in short courses, and the amount depends on whether it's an injection or a capsule. Here's each pattern, where it comes from, and the math for a 20 mg vial.

Crystagen dosage chart
Where each amount comes from
Three patterns are in circulation, and what separates them most is the form. The injection rows are in micrograms and the capsule row is in milligrams, so keep those two apart before anything else. Every figure is a convention from education pages or a capsule label rather than a trial result, so read the source column with the amount. Background on the peptide is on the Crystagen page.

Crystagen injection dosage and mixing
Research vendors sell Crystagen as a freeze-dried powder, usually in 20 mg vials. You mix it with bacteriostatic water, which is sterile water with a little preservative so one vial can be drawn from more than once. The injection patterns in the chart are for this powder, injected under the skin.
The table shows the units to draw on a U-100 syringe, which holds 100 units in 1 mL, for 1, 2 and 3 mL of water. The amount is 200 mcg, from peptide education pages.
| Water | Strength | 200 mcg dose |
|---|---|---|
| 1 mL | 20 mg per mL | 1 unit, hard to measure |
| 2 mL | 10 mg per mL | 2 units |
| 3 mL | 6.7 mg per mL | 3 units |
The 200 mcg amount is from peptide education pages. Units are math from that amount, with strength rounded to one decimal. "Hard to measure" means the draw is below about 2 units, smaller than most U-100 syringes mark clearly.
A 20 mg vial is a lot of Crystagen for a dose this small, so every draw is tiny. More water makes each dose bigger on the syringe and easier to read. At 5 mL, if the vial has room for it, 200 mcg is 5 units. For any other water volume or amount, the reconstitution calculator does the same math.
Mixing follows the same steps education pages give for any freeze-dried peptide. Let the vial come to room temperature, wipe the stopper with an alcohol swab, and run the water slowly down the inside wall of the vial rather than straight onto the powder. Then swirl gently until it's clear, without shaking, and write the date on the label so you know when the 28 days run out.
The supplies are the ordinary ones. Bacteriostatic water comes in small multi-use vials, and U-100 insulin syringes are the ones the units in the table refer to. Many people buy short syringes marked in single units, because at these amounts the difference between 2 and 3 units is a 50% change in the dose. A syringe is single use, one per dose, so a 10-day course is ten syringes and one vial, and the counts are supposed to differ.
Crystagen capsule dosage
The Russian capsule is labeled at 10 to 20 mg a day by mouth for 10 to 20 days, repeated two or three times a year. Capsules are commonly 10 mg each and come in boxes of 20 or 60, so the label range is one or two capsules a day, and a box of 20 covers a 10-day course at two a day or a 20-day course at one.
That's 50 to 100 times the injected amount. The usual reason given is that a swallowed peptide is mostly broken down in the gut, so capsule makers allow for the loss. Nobody has measured how much Crystagen gets through, which is why the two forms aren't converted into each other here.
When and how often
Once a day. The daily patterns use a single dose during the course, per peptide education pages and capsule labels.
Ten days for injection, ten to twenty for capsules. Education pages give a 10-day daily injection course. Capsule labels give 10 to 20 days.
Every other day, sometimes, after the course. Education pages also describe 200 mcg every other day after the 10-day daily course. They don't give an end date for that phase, so it's the least defined pattern in the chart.
Months off between courses. Education pages give 4 to 6 months off between injection courses, and capsule labels give two or three courses a year. None of it comes from a study that compared schedules.
Time of day. No study or label sets one. People pick a time they can repeat every day of the course.
For planning, a 10-day injection course at 200 mcg a day uses 2 mg of peptide. A capsule course at 10 to 20 mg a day for 10 to 20 days uses 100 to 400 mg.
| Course | Daily amount | Total peptide |
|---|---|---|
| 10 days, injected | 200 mcg | 2 mg |
| 10 days, capsules | 10 mg | 100 mg, 10 capsules |
| 10 days, capsules | 20 mg | 200 mg, 20 capsules |
| 20 days, capsules | 10 mg | 200 mg, 20 capsules |
| 20 days, capsules | 20 mg | 400 mg, 40 capsules |
The injected amount and course are from peptide education pages, and the capsule amounts and lengths from Russian capsule labels. Totals are math, with capsules counted at 10 mg each.
The table is the one to keep in mind when you shop. An injection course needs a few milligrams, so any 20 mg vial is more than enough, and the question is only whether the vendor's per-milligram price and lab report hold up. A capsule course needs a box or two, and the per-capsule strength printed on the box sets how many you need.
How long a vial lasts
On paper a 20 mg vial at 200 mcg a day lasts 100 days. In practice the mixed vial goes on a 28-day clock in the fridge the day water goes in. A 10-day course at 200 mcg a day uses 2 mg, so the vial expires with about 18 mg left, enough for nine more courses if it kept.
So one vial covers one course, including an every-other-day follow-on if it fits inside the 28 days, and most of the peptide won't keep until the next course months later. It's a buying point more than a dosing one, because the cost of a course is really the cost of a vial. Unmixed powder keeps far longer, and vendor pages give 2 to 8°C (36 to 46°F) in the fridge as the storage range.
Taking Crystagen with other bioregulators
No study or label sets a combined human schedule, and nothing here comes from a tested pairing. People who use more than one of the Khavinson immune peptides describe separate courses in the same part of the year, each at its own amount, and that's reported use. Vilon is the one most often paired, and its patterns are on the Vilon dosage page. Thymalin, the thymus extract Crystagen was modeled on, is the other. Thymalin is a mixed extract rather than a single peptide, so its amounts don't line up with Crystagen's, and each one is measured by its own label or source.
If you're comparing your options before choosing one, the Thymosin alpha-1 page covers the immune peptide with the most human research behind it, and it's often where people start before narrowing down to a Khavinson peptide.
Signs the amount or timing is off
These are reported experiences from people who use Crystagen, not findings from a study.
Redness or itching where you injected. People report it, usually mild and gone within a day. They rotate the spot, and some stop the course if it lingers.
Feeling run-down or achy early in a course. It's reported now and then. People usually pause and recheck the math first, since a decimal slip on a 20 mg vial turns micrograms into milligrams.
Mixing up the two forms. The most serious mistake people describe isn't a side effect, it's applying the capsule amount to the vial. Ten milligrams injected would be 50 times the 200 mcg on education pages, and it would empty half a 20 mg vial in one draw. If a dose ever looks like a large share of the vial, people stop and recheck which form the number belongs to.
Nothing noticeable at all. This is the most common report, which fits a peptide aimed at slow immune changes. People don't usually raise the injected amount, because no source gives a higher one.
No completed human safety study exists for Crystagen. What's known and unknown is on the Crystagen page. Before buying, the per-milligram price and a recent third-party lab report on identity and purity are the two things to check.
It's sold for research, and the big human trials haven't been run yet.
Questions people ask about Crystagen dosage
How much bacteriostatic water for 20 mg of Crystagen?
It depends on how small a draw you can measure. With 2 mL, 200 mcg is 2 units, and with 3 mL it's 3 units. With 1 mL it's 1 unit, which is hard to read on a U-100 syringe.
How much Crystagen should I take per day?
Education pages give 200 mcg a day for the injectable powder. Capsule labels give 10 to 20 mg a day, and the two don't swap, because each belongs to its own form.
Can you take Crystagen every day without a break?
No study or label sets daily use with no stop date. Every pattern in circulation is a short course followed by months off.
Can you take Crystagen with Vilon or Thymalin?
No study or label sets a combined human schedule. People who use more than one of the Khavinson immune peptides describe running separate courses in the same season, which is reported use rather than tested use.
How many Crystagen capsules a day?
Capsules are commonly 10 mg each, and labels give 10 to 20 mg a day, which is one or two capsules. Check the strength printed on your box, since it sets the count.
