Also known as
T-400
T-400 is a common alias for trenbolone acetate, an injectable anabolic steroid. This page covers the two products available at SynthesisGear: Prime and Magnus brands, both containing 100 mg/ml in 10 ml vials. Athletes typically use this compound to support strength and lean mass gains. Users should be aware of potential side effects, including suppression of natural testosterone production and possible cardiovascular strain. Regular monitoring is advised for individuals using trenbolone acetate.
Identity and Manufacturer
T-400 refers to trenbolone acetate. SynthesisGear stocks two versions: one from Prime and one from Magnus. Both are classified as injectable steroids. The short ester means more frequent dosing is typically required to maintain stable blood levels. No other esters of trenbolone are listed in this shop.
Product Comparison
The only differences between the two available trenbolone acetate products are the manufacturer and the brand. The concentration, vial size, and recommended administration route are identical. Buyers can choose based on their preference for Prime or Magnus. Neither product contains added excipients that would alter its pharmacological profile.
