This formulation delivers testosterone in a 5% concentration metered pump dispenser, a significantly higher concentration than CSD’s 1% AndroGel packets, with F40 Biotech’s metered pump delivery system providing a distinct application method from individual single use sachets. Each pump actuation dispenses a consistent metered dose, supporting precise repeatable dosing across the 60 pump supply without the per packet portioning of sachet based gel formulations.
The 5% concentration represents a meaningfully different research presentation from CSD’s 1% AndroGel listings. At five times the concentration per gram of gel, the 5% formulation allows researchers to achieve equivalent testosterone delivery from a substantially smaller gel volume per application. A relevant consideration in transdermal research examining the relationship between applied gel volume, skin surface area, and percutaneous absorption efficiency. Higher concentration transdermal formulations have generated specific research interest in comparative absorption kinetics, as the relationship between gel concentration and absorbed testosterone fraction is not necessarily linear making 5% versus 1% concentration comparison a relevant variable in transdermal bioavailability research.
The metered pump dispenser format addresses a practical research consideration distinct from individual packets. Pump dispensers provide consistent per actuation dosing across the full 60 pump supply from a single container, whereas packet formats require opening a new single use unit for each application. This delivery mechanism difference is relevant to research examining application consistency, dose to dose variability, and the practical handling characteristics of different transdermal testosterone delivery systems. Variables that complement the underlying percutaneous absorption and HPG axis modulation research shared across all of CSD’s transdermal testosterone presentations.
F40 Biotech formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks transdermal testosterone across both 1% AndroGel packets and this 5% F40 Biotech metered pump format, giving researchers concentration and delivery mechanism flexibility from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Store at room temperature away from direct light and heat. Wash hands thoroughly after application. Intended for research purposes only.

Testosterone Gel 5% is a transdermal androgen formulation containing testosterone in a metered pump dispenser. This F-40 Biotech Germany product is supplied in a 60 pump format designed to provide a consistent quantity of gel with each complete pump actuation.
Testosterone gel is applied to the skin, where testosterone is absorbed through the skin into systemic circulation. Testosterone then binds to androgen receptors in responsive tissues and produces the biological signaling associated with endogenous testosterone.
Prescription transdermal testosterone products are used as testosterone replacement therapy in adult males with testosterone deficiency associated with certain medical forms of hypogonadism. Diagnosis and treatment require appropriate clinical assessment and laboratory confirmation of low testosterone.
Testosterone gel delivers testosterone gradually through the skin, while injectable testosterone formulations deliver the hormone through intramuscular or subcutaneous administration depending on the specific product. The different delivery routes produce different absorption and pharmacokinetic profiles and are not directly interchangeable.
Testosterone gel can transfer from treated skin to another person through direct contact. Children and others should avoid contact with unwashed or uncovered application sites. Testosterone therapy also requires medical monitoring because it can affect hematocrit, cardiovascular risk factors, prostate related parameters, fertility, and other androgen sensitive systems.
