You pm'ed me a goal of 10-15lbs.
If you are looking for a true prohormone I would suggest either ANDRO FACTORY BULK-UP and or P-BOLD. Both are mild on sides which I find to be more and more important as we get get older(not calling you old by any means, what I mean is at 30 myself I find the sides far worse than when I was 21 and generally this is the case when I talk to others). A 6-8 week cycle of these can reap 10-15lbs. I would say 10 for sure but if everything is done perfect 15lbs is achievable. Of course I rep for AF so I recommend them but some other options are AMS 4ad, 1ad, and Forerunner Labs Alphamass and Alphabulk. These are all true prohormones.
As far as the methylated designer steroids I personally do not like the trens as they seem to trash my libido more than others(this again is worse as I age). With tren and SD eliminated that leaves us with EPI and HALO and LMG, MSTEN, dymethazine and a few others. Pretty much any of these can get you 10lbs in 6 weeks. Make note these are all going to be harder on the body with more sides. Some will argue that they felt no sides but you can't feel certain sides and only those with pre, during, and post cycle blood work can really say they had no sides.
Both options will get you there is is just a matter of how long you want to take and what kind of trip you want.
