It's puffy size in a bottle. With daily injections of this fake fat oil you could put 2 inches on your arms in a couple weeks. It's also supposed to stretch the muscle fascia-allowing for more growth(I question these claims). After some time you can do maintenance injections once a week or so to keep the size added. Up until then you will feel like a human pin cushion. If you stop using it, the size will dissipate over a few months.
The size added is obvious-but it isn't pleasing to the eye. It's balloonish/fake looking. You can also get bruising. The only use I see for Synthol is to bring up a lagging bodypart before a show. Even then, that bodypart will not be peeled by any means. It will just be bigger-which in some cases could help???
Also the repeated spot injections are a recipe for an abcess. I should know. I used an older version of Synthol(Pump-n-Pose) and got an abcess in my tricep. Dr lanced it and drained over 50 ccs of pus. It was pretty gnarly and I had to continue to drain it daily for a week 2x a day. A shot of anti b's and oral anti b's too were given to me. It healed well, but left a small indentation in my tri that will be there for life. Also, what this stuff does to the body long term is still up for grabs.
For being a retired BB competitor, I still consider myself pretty hardcore in the RX enhancement dept. Keeping that in mind, Synthol is in my personal list of compounds I will never use-or never use again, along with insulin, dnp - dinitrophenol - , Cheque Drops, methyl test and IGF. The risks just aren't worth the rewards.
