I have researched with helios on a few occasions while preparing for a show.
I do believe in site/spot reduction when on a supra-physiological dose of hormones and already lean, but have those damn last little areas that are stubborn ----glutes, lower back, lower abs....
I believe in Helios and also topical fat loss given you are doing cardio, insulin is controlled and calories are deficient.
When researching helios start with 1/2 ml or .025 per side of body.
Give the lower back small "botox-like" injections per side --around 5 spaced out. Then repeat on the opposite side.
As you get accustomed to the effects you increase dosage -- up to 2ml max....
I do not see a huge problem using the same pin to complete the multiple site injects either....
I also recommend combining this ON TOP of topical yohimbine HCL + capsaizen to really target stubborn areas...
I look at it like this --- Either catabolize 1/2inch off your biceps and quads for the lower back or abs.....or give those areas a REASON to oxidize by using these awesome methods....
