Why buy this product

Testosterone Undecanoate by Transparent Labs USA is an ester of the androgenic hormone testosterone that is used in strength sports to build muscle. It is prescribed to increase insufficient levels of endogenous testosterone and reduce signs of hypogonadism.

Application and dosage of Testosterone Undecanoate

To achieve a positive result, it is required to administer up to 1000 mg of the drug once every 2-4 weeks. So that a bump does not form at the injection site, the solution must be administered slowly. Injections should be made in large muscle groups: buttocks, deltas, outer side of the thigh.

As studies have shown, testosterone undecanoate does not have a toxic effect on the liver, since when absorbed from the gastrointestinal tract it enters the lymph (not into the blood), with the flow of which through the common lymphatic duct enters the general bloodstream, i.e. the liver. In the body, undecanoate is converted to dihydrotestosterone, the active metabolite of testosterone, which means that the substance is actually a prohormone.

Post Cycle Therapy Testosterone Undecanoate

Due to the ability of the injectable steroid to slightly affect testosterone production, after two weeks after the last injection, it is necessary to carry out post-cycle therapy using Clomid or tamoxifen at dosages as for the lightest cycle.
