These side effects are typically the result of the body adjusting to the Buy HCG hormone and should dissipate within a few days. Some people may also experience a change in their menstrual cycle while Buy HCG. 

However, this is not considered a side effect, but rather a normal response to the hormone. More serious side effects are rare, but they can occur.

These side effects include ovarian hyperstimulation syndrome (OHSS), which can be painful and cause nausea, vomiting, and diarrhea. In rare cases, OHSS can be fatal. Another rare but serious side effect is multiple births.

This is more likely to occur if Buy HCG is taken in conjunction with another fertility medication. If you experience any serious side effects, you should stop Buy HCG and consult your doctor immediately.

Overall, Buy HCG is a safe and effective way to treat fertility issues. However, as with any medication, there are potential side effects that you should be aware of. If you experience any serious side effects, you should stop Buy HCG and consult your doctor immediately.
