A freeze-dried vial comes in powder form. To put it back into solution in the laboratory, three things are enough: a solvent, something to draw it up with, and something to disinfect the cap between two passes. It is this material that we check directly on each vial card.
All four options in one vial
- Bacteriostatic water 3 mL — solvent with 0.9% benzyl alcohol. Storage details are in the guide bacteriostatic water.
- Set of 10 syringes + 10 swabs — the starting kit, the same content as the free kit.
- Box of 100 1 mL syringes — when 10 syringes do not cover the series of draws.
- Box of 100 alcohol pads — one swab per pass over the cork, then throw away.
The quantity added follows that of the vial: two vials, two waters if the box is checked. Nothing is pre-checked.
The free kit from €99.99
From 99,99 € the vial — this is the case of the vial R3TA 20 mg — the command displays two lines at 0 € : bacteriostatic water and set of 10 syringes + 10 swabs. One set per vial. Cheaper pens, sprays, and vials do not include them.
If you still check the water or lot on the form, in addition to the kit or instead, they go to 4,99 € instead of €9.99. Purchased alone, from their own sheet, they remain at €9.99. The boxes of 100 are not affected.
Reconstitution schedules, working dose and frequency of each peptide are on the protocols. The volume of water is then converted into the calculator.
Pen: needles, no kit
A pre-filled pen does not need water or a reconstitution syringe. On its sheet, two choices of needles are mutually exclusive: 10 needles or 100 needles 32G × 4 mm. Alcohol pads remain a separate category.

Frequently asked questions
What does the free kit contain?
Bacteriostatic water and a set of 10 syringes + 10 swabs, each for €0 in the basket. This is free with each vial starting at €99.99, including the R3TA 20 mg vial. Once per vial ordered.
Does the kit come with a pen or a spray?
No. The pen is already in solution and the spray too. The kit only concerns lyophilized vials starting at €99.99.
Should you still buy a box of 100?
The pack of 10 is enough to get you started. The box of 100 syringes or 100 swabs is used when the laboratory makes draws one after the other. It is checked on the form, in addition to the kit.
What about a pre-filled pen?
No water or reconstitution syringe. On the pen sheet, choose a box of 10 needles or a box of 100 (32G × 4 mm), and possibly the alcohol pads.
