CJC-1295 no DAC: dosing, reconstitution and evidence

A modified GHRH(1-29) fragment without the albumin-binding complex. Produces a sharp, short GH pulse that closely mimics natural release — the reason it is usually preferred over the DAC version.

Also known as Mod GRF 1-29, Modified GRF, Sermorelin analog

For women

Women commonly run 60–80% of cited doses, and some time GH peptides away from the luteal phase to limit water retention.

What people actually run

The community standard GHRH, run with Ipamorelin. Widely regarded as preferable to the DAC version for mimicking natural pulses.

This is accumulated community practice — years of real-world use across a large number of people, converging on numbers that work. It is not a controlled trial, and for most compounds here no such trial exists or is ever likely to. That makes this the most reliable dosing signal available, and it is a good deal better than guessing.

What to expect

Most people tolerate CJC-1295 no DAC well. Here is what is worth knowing going in, so nothing catches you by surprise.

Must be dosed on an empty stomach — carbohydrate or fat within ~2 hours blunts the GH pulse. Nearly always paired with a GHRP for synergy.

Known interactions

Interactions involving CJC-1295 no DAC's drug class that DoseIQ screens for. Each one cites where it comes from — an FDA label section or the published record — because an interaction warning you can't trace is just noise.

Caution GH peptides push blood sugar against your diabetes medication

Growth hormone raises glucose and insulin resistance — it works directly against glucose-lowering medication.

What to do: Fasting glucose and HbA1c are worth tracking; medication doses sometimes need adjusting. Your prescriber should know GH peptides are in the picture.

Reconstitution guide

CJC-1295 no DAC ships as a lyophilised powder and gets mixed with bacteriostatic water before use. How much water you add sets the concentration, which sets how many syringe units make up each dose. One unit on a U-100 syringe is 0.01 mL — the tables below do the arithmetic for the vial sizes you are most likely to be holding.

10mg vial most common

Water addedConcentration 100mcg
2mL (common) 5 mg/mL0.02 mL
2 units
3mL 3.33 mg/mL0.03 mL
3 units

5mg vial

Water addedConcentration 100mcg
2mL (common) 2.5 mg/mL0.04 mL
4 units
3mL 1.67 mg/mL0.06 mL
6 units
10 mg vial + 3 mL BAC water = 3,333 mcg/mL — a 100 mcg dose = 3 units on a U-100 syringe. 5 mg vial + 3 mL = 1,667 mcg/mL — 100 mcg = 6 units.

Standard steps

  1. Inspect the vialConfirm the label and that the powder cake is intact. Do not use a cracked or compromised vial.
  2. Let it reach room temperatureSitting out for a few minutes reduces condensation inside the vial when the seal is broken.
  3. Disinfect both stoppersWipe the compound vial and the bacteriostatic water vial with a fresh alcohol swab and let them air-dry.
  4. Draw the bacteriostatic waterUse a sterile syringe to draw the volume you have chosen from the reconstitution table.
  5. Add the water down the vial wallInject slowly so it runs down the inside wall rather than spraying directly onto the powder. This limits foaming.
  6. Dissolve gentlySwirl or roll the vial between your hands until the cake dissolves. Never shake — agitation damages peptide bonds. The solution should end up clear.
  7. Label and refrigerateWrite the reconstitution date and concentration on the vial. Store at 2–8°C. Do not freeze.
