Semaglutide Pen – 4mg

Semaglutide is a long acting synthetic GLP-1 receptor agonist with a half-life of approximately 7 days, achieved through fatty acid chain conjugation enabling albumin binding and protection against DPP-4 enzymatic degradation. This fixed dose pre loaded pen delivers 4mg total Semaglutide at 1.34mg/mL concentration with four disposable needles included. A distinct presentation from the adjustable dose pen variants in CSD’s Semaglutide range, providing a ready to use fixed dose delivery system where the pen mechanism delivers consistent pre set doses without the manual dose dialing required by adjustable pen formats.

The fixed dose pre loaded format serves a specific research purpose from the adjustable dose pen presentations. Adjustable dose pens allow researchers to dial variable dose increments across the pen’s supply, suited to titration protocols where dose escalation or reduction across the research timeline is a required experimental variable. The fixed dose pre loaded pen delivers consistent pre set doses at the 1.34mg/mL concentration throughout its usage. Suited to protocols where dose consistency across every administration is the priority variable rather than titration flexibility, and where the simplicity of a fixed delivery mechanism reduces administration variability between research operators or across multiple time points. The four included disposable needles provide a complete ready to use system matching the pen’s usage capacity without separate needle procurement.

CSD’s Semaglutide pen range now spans both fixed dose and adjustable dose format options: this fixed dose pre loaded 4mg pen, the generic brand 2mg adjustable single pen, the generic brand 4mg adjustable 2 pack, and the F40 Biotech 4mg adjustable pen,  alongside the 9.6mg fixed dose prefilled pen and the iLab Pharma 5mg and 10mg lyophilized vials. The fixed dose versus adjustable dose distinction is the primary format selection variable within the 4mg concentration tier, with researchers selecting based on whether dose consistency or titration flexibility is the priority research requirement.

Every batch of CSD’s Semaglutide pen is third party lab tested for concentration accuracy and purity before being made available, with COA documentation available on request.
