A few:
R-Andro Shred, with liposomal delivery served me VERY well the first time I used it years ago. The product has seen some changes over the years, and that led me to choose other sources. I do still have some though....very few.
Nutra Innovations which features 50mg Androsterone with TetraSorb delivery (used to) was my next choice, and I ordered 4-5 bottles. I tended to run 4-5 caps per day, and the quality was definitely evident for me. I have had excellent experiences with many TertaSorb products.
In terms of Epiandro, I have mostly used Androvar. The quality always seemed to be there, and I had always liked the versatility of the 100mg capsules- especially since the half life is so short.
I actually just got my Alpha-7 today! I almost slapped some on myself after getting home from work. I chose not to because I have like 2-3 acne cysts on my forehead from working in some Androvar (Mostly PWO) lately. They are pretty bad, so I want to get these under a bit more control...at least for tonight...haha.
I am one of those people that works in a few runs of Epiandro and/or Androsterone per year. It’s tough to beat that feeling you get when using such products preworkout! I bought the Alpha-7 to take advantage of the sweet deal, though I am not necessarily sure if I will be utilizing it at this time for a committed run. Maybe I will decide tomorrow. If I try it and love it, the decision will be made rather easily
