I don't think they are the same, at least that has not been my experience, despite what it says the solutuon contains. I started a thread a while back talking about how I read a study that there was tremendous inconsistency with compounded testosterone, but it was with compounded creams & gels. I think so many guys on this site have done a great job at getting their protocol dialed in, and as a result very rarely, if ever, change where they get their testosterone from. I was going to a TRT clinic for weekly injections and they changed compounding pharmacies a couple times. I could always tell and would bring it to their attention, as they didn't tell their patients (why would they, testosterone is testosterone). I've been self injecting with Perrigo for 3 months and have had really hard erections when I wake up but very little strength gain in the gym. I switched to Westward 10 days ago and have had no morning wood for about a week, yet I seem to be much stronger in the gym. Haven't you guys taken different drugs, brand name and generic, and since the ingredients on the side of the bottle are identical, you go against your better judgement and choose the lesser priced generic, only to find it doesn't work near as good as you remember the brand name working in the past. Some of you guys have this down so well and feel great so there's no need for you to alter anything, but if you tried T from a different source, your experience may be similar mine.
