Information on these two injectables?

[jlbspd]

I have some HGH but my question was on two others i have, Nandrolone ND-300 and Trenbolone TA-100. What exactly are these two and what are the benifits and side affects of them. I have acquired them but have no intentions of using them just yet. Im still training, trying to get to my natural potential 1st.
Im 5-11 and 190lb and have always been a light weight imo...seems to run several generations back. Also have fine thinner hair....could be issues with just about any right?
Just trying to get info on them and what to expect + & - and exactly what each one is. Which one if any would be best for 1st time? What should be taken if anything along with them. What about the boys down stairs? i have dick pills. Will either one have major neg affects in that department? will those pills take care of issue?
Thanks for the info, sorry for asking so much and im sure these have been covered in the past.
