Op, you'll be fine for one week. Take your shot the day you leave and resume the day you return. If it's prescription HCG you could buy an insulin travel kit and take it with you. If so, I'd only take as little as possible so you can heave it when done.
Here's the thread you referred to Fit:
Low dose Naltrexone on next cycle
Scally's opinion seems to be against it at this time.
From Wiki:
Low-Dose naltrexoneMain article: Low dose naltrexone
"Low dose naltrexone" (LDN) describes the "off-label" use of naltrexone at low doses for diseases not related to chemical dependency or intoxication, such as multiple sclerosis.[14] Preliminary research suggests low dose naltrexone may be useful in preventing opioid tolerance and dependence when combined with an opioid,[15] reduce the severity of opioid withdrawal,[16] or improve fibromyalgia symptoms,[17] though much more research needs to be done before it can be recommended for clinical use.
Although there have been dramatic claims about its efficacy in treating a wide range of diseases including cancer and HIV, these claims are not generally supported by scientific evidence.[14] This treatment has gotten significant attention on the Internet, especially through websites run by organizations promoting its use.[18]
A single-blind randomized, two-group clinical trial of Low Dose Naltrexone for HIV/AIDS was conducted in Mali from March 2008 to March 2010, published in the Journal of AIDS and HIV Research.[19] The authors concluded that adding LDN to a three-antiretroviral regime used improved the recovery rate of CD4 count, suggesting "further exploration of LDN as part of an HIV+ treatment regime is warranted."
A single-cohort study of Low Dose Naltrexone in 55 HIV-positive asymptomatic untreated patients with CD4 counts between 350-600 was conducted in 2008-2009. This study showed CD4 percentages maintained without loss over the study's nine-month period.
Fit, have you continued to use it? If so, your thoughts please?
