Semax

Cognitive & Mood Reduce Inflammation

10mg vial + 2mL BAC water = 6 units = 300mcg — Amounts listed in the Dosify Me data: 300-1000mcg — Frequency: daily, 10-day cycles — Best taken: mornings

Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.

Reconstitution

Every vial size below is mixed to the same concentration, 5 mg/mL, so the syringe reads the same number of units for a given dose no matter which vial you bought.

VialBacteriostatic waterConcentration
5 mg1.00 mL5 mg/mL
10 mg2.00 mL5 mg/mL

Dose to syringe units

On a standard 100-unit (1 mL) insulin syringe, at the concentration above:

DoseSyringe units
300 mcg6.0 units
500 mcg10.0 units
800 mcg16.0 units
1 mg20.0 units

Amounts listed in the Dosify Me data: 300–1000 mcg. Frequency: daily, 10-day cycles. Timing: mornings, any consistent time.

No single consensus protocol — community subcutaneous protocols are reported at 300-1000mcg once daily, titrated gradually. All vial sizes reconstitute to 5mg/mL (50mcg/unit) so the syringe reads the same regardless of size.

Reading units for Semax

Check one row of the table above: 300 mcg is 0.3 mg; 0.3 mg ÷ 5 mg/mL = 0.06 mL; 0.06 mL × 100 = 6 units.

What users report

Anecdotal and early-research reports, kept apart from the evidence above. Not clinically established.

Side effects

Medication caution

No study, case report or label describes Semax combined with an MAOI. The concern rests on mechanism — Semax is reported to affect brain monoamine signaling, and MAOIs block the breakdown of those same monoamines — so it is an untested combination with a plausible reason for caution, not a documented danger. Overlap with SSRIs/SNRIs is the same kind of unstudied concern. Talk to your prescribing doctor before combining with any antidepressant.

Frequently asked

How many units is 300 mcg of Semax?

At 5 mg/mL (the concentration every vial size mixes to), 300 mcg of Semax is 6.0 units on a 100-unit insulin syringe (0.060 mL).

How many units is 500 mcg of Semax?

At 5 mg/mL (the concentration every vial size mixes to), 500 mcg of Semax is 10.0 units on a 100-unit insulin syringe (0.100 mL).

How many units is 800 mcg of Semax?

At 5 mg/mL (the concentration every vial size mixes to), 800 mcg of Semax is 16.0 units on a 100-unit insulin syringe (0.160 mL).

How much bacteriostatic water do I add to a 5 mg vial of Semax?

1.00 mL, which gives 5 mg/mL. Other vial sizes use proportionally more or less water so the syringe reads the same.

How much bacteriostatic water do I add to a 10 mg vial of Semax?

2.00 mL, which gives 5 mg/mL. Other vial sizes use proportionally more or less water so the syringe reads the same.

How often is Semax taken?

Daily, 10-day cycles. Mornings, any consistent time Typical cycle: ~10 days on, ~1 week off; repeat as needed.
