Unfortunately, have experienced this side effect on numerous runs with HGH. Some things that have helped me include: increasing overall hydration/electrolytes (huge factor for me while training in Yucatan), increasing fish oil significantly (3-6g), adding something like bone broth/collagen/cissus quadrangularis, adding diuretics such as dandelion root or HCTZ, using sauna, and trying to back down off or further split up your dosage.
Another area to consider is your training intensity, frequency as a whole. When I run cycles like that my endurance goes absolutely threw the roof and I basically want to train non-stop. Lifting, cardio, swimming, hiking etc My energy and recovery levels can be deceptive and without intentionally pumping the brakes, I feel its easy to over train. One of the first clues would be wear and tear, feeling worn down, or maybe extra pressure on joints.
