One thing I can say from looking at photos of these guys, is that their skin was light years better than what you see on stage today. I don't know if it was from the lack of oil that most are using now or what, but their skin was crystal clear with no acne or blemishes.
Now Jeb did say the only draw back was that the Winstrol V did burn sometimes going in.
Both the Winstrol and Test suspension were brutal as far as injection pain goes. Big crystals of hormone causing pain. Today they have those micronised just like creatine can be micronised, the UG labs, unlike the few human equivalents available. Kind of ironic. They also clogged up needles which caused much frustration. You had to kind of shake it around in the syringe and then quickly jab it in and start pushing almost before you got in. Putting a little streroid oil in the syringle was one trick to lubricate the needle.
Many don't ever get acne no matter the dose. I think the skin looked thinner because they didn't use as many of all the drugs, insulin and GH causing water retention. Plus everyone is always concerned with being "full" all the time. Actual subq fat levels are lower today, especially in certain areas. But of course, the GH does cause "fat burning," no question about it.
Some coaches fairly recently had their guys eat all fish on prep, the idea being that fish protein caused the collagen in the skin to become thinner giving a tighter look
