I'm not sure what is 'cool' or not these days, lol. There are some with maybe mystique behind them with legendary status
I started in the 90's, so all the 80's stuff was legendary to me
Like Negma Parabolan, Finajet, Searle Anavar, 2902 Anadrol, etc. lol
I used everything Mexico had to offer in the 90-'s. Then, in the 2000's, used more, and shifted to UGL. I used Brazilian Hemogenin, the best dbol on the planet called DUPA from Indonesia made by SYNTEX, etc., but I missed the 2902 Anadrol down in Mexico. Syntex started making the newer pink batches down there in 1994, and I swear i was one of the first to use it. It took about a year for it to get popular, then the price went up. The newer pink tabs were in blister packs. We used to get them from the hospital in TJ, and if they didn't have it, there was a guy named Randy who owned a pharmacy down there who could get them for us. There was also Chavez and Miguel from the pharmacy on 4th and Revolution (next to the Guess store) who could get them for us too. There were a few other ways of getting them/stuff down there, but I tried to avoid going certain routes from wrong people if i could. Duchaine had the pinks tested around 1997, and then it just exploded, and the price really went up from there. There were fakes in the amber bottles.
Reforvit was like $18/bottle for the longest time, then went up as the years went by. Loeffler came out with tabs around 2000 IIRC, and they worked great too. Shit was a bargain for the price, especially during that period where dbol was kind of not readily available unless you got pink Thais or from other countries.
I will spare listing all the Mexican compounds, but i'm certain I used them all. Syntex made a low dosed test blend down there for a few years before it was d/c....can't remember the name, but it was great for a low concentration.
Zambon Winstrol and yellow top Organon were top of the line and have legendary status to me. Both were awesome. Then there was Steris Cypionate and Suspension that were strong as hell. Later used Schein enanthate and suspension too, and they were great.
I mentioned pink Thais above...so many good dbol back in the day.
Was using Finiplix pellets in the 90's with DMSO before kits became more available by Animal, MrT (or was it Mr. H?), and Dazed.
Polish Omnadren were phenomenal, and CHEAP form many years.
I'll stop here. I think maybe the OP is asking about uncommon cool stuff?
If so, i'd say Duchaine's choice, Anatrofin, would have been
cool to use
I never used that!!!
