If recommended by Dr. Haney, your testosterone injection will be combined with a separate LH Support injection at each visit. Having a LH (luteinizing hormone) analog is important for maintaining the HPG axis to create a more leveled-out experience. Meaning, testosterone levels will peak within the first few days post-injection.
Following this peak, those levels will slowly recede leading up to the next injection in succession. This process is cyclical, which explains why most men feel better at the beginning of their injection week vs later.
Having LH support upholds the HPG axis, so men will sustain blood-testosterone levels more evenly once those levels recede post-injection. This will also alleviate some of the symptoms that would usually come with the "peak and valley" effect.
