Bolfortan, a.k.a. testosterone nicotinate, is testosterone with the nicotinic acid ester, a slow-acting long ester added to it. Nicotinic acid is better known as niacin, the cholesterol and triglyceride lowering member of the B vitamin family. Bolfortan is often referred to as Test Nic.

More specifically, the nicotinic ester (similar to enanthate) was developed to increase the time released duration of testosterone, thereby reducing the frequency of injections for hormone therapy patients to monthly shots. Bodybuilders typically reduce their dosages and increase frequency, shooting it twice weekly in order to keep their blood concentrations level. This method works to more effectively stave off many of the negative side effects largely associated with high and low alternating blood serum concentrations. Bolfortan users should inject twice weekly like other long esters, which is often enough to keep blood serum levels well above baseline with this particular drug.


Steroid Form

Bolfortan is no longer produced as a prescription medication, but was provided in 50 mg/ml dosages within a 1 ml ampule.
