B7-33 Pre-Mixed Peptide Pen
B7-33 is a synthetic single-chain peptide derived from human relaxin-2 and examined in research involving the RXFP1 receptor, extracellular matrix regulation, fibrosis biology, and connective tissue signalling. Direct SARMS Slovakia supplies B7-33 in a 2 mg pre-mixed pen format, with a reusable pen kit or individual pre-mixed cartridges.
Benefits of the pre-mixed pen format
1
The formulation is pre-mixed. The peptide is provided in liquid form so that researchers do not need to reconstitute a lyophilized product before use.
2
Controlled dispensing. The pen mechanism allows researchers to choose and dispense precise volumes consistently throughout the procedures.
3
Convenient format. It is a convenient format because it combines the peptide formulation and dispensing mechanism in one compact design.
4
Reduced handling. Less handling is involved because the formulation is already inside the pen; unlike conventional vial formats, fewer steps for preparation and transfer are needed.
5
The preparation is straightforward. Since the mixture is already prepared, it makes laboratory handling easier by removing the need for separate reconstitution and liquid transfer.

Got a question about this B7-33 compound?
A pre-mixed peptide pen, is a pen-format research product containing the B7-33 peptide already prepared in a liquid solution at a specified concentration. Unlike a lyophilized peptide vial, it does not require reconstitution before laboratory analysis or experimental research and should be stored and handled according to the supplier’s stated conditions.
The B7-33 Pre-Mixed Cartridge and pen kits are supplied in 2mg.
No, B7-33 pre-mixed peptide pen kits and cartridges from Direct SARMs are already reconstituted with Bacteriostatic Water, ready for research use.
Pre-mixed peptides supplied by Direct SARMs [name]: refrigeration stability varies by ingredient, formulation, concentration, and storage environment. Researchers should use available stability or analytical data and follow product-specific storage guidelines, as there is no universal stability period.
