They are fine but I would prefer to use something like Hyge’s if I could afford to. they are known for their consistent high quality. that said, N has some of the best connections in the business and he’s going to supply stuff that he is confident in. Thats how he’s stayed in the game this long ;).  At 54, you will probably get a very nice effect from it. I would use 3iu every day, taken either first thing in the AM or preworkout. I would suggest the wife started at 2iu ED. Keep in mind the effects are not as dramatic as steroids. You’ll get better recovery and better body comp over the long haul. At your age, you can really stay at this dose from now on. No need to cycle off. This would be a good therapeutic dose to continue
