I am currently taking Nebido for TRT which works great. I took my first injection and felt a little, then after 6 weeks I took my second injection and felt all the benefits after the second injection. I am however considering switching to Sustanon because it looks like it will come out to be way cheaper. My question is if I switched to Sustanon and wanted to come back to Nebido, would I have to Front Load it again? I may want to come back to Nebido because I travel and don't want to have to get injections when I am away and the first injection of Nebido was so so, but the second one after 6 weeks was great.
