I was wondering if this is a good stack or if anyone has done this stack before..?

It can be done sure, if you havent used each solo I would probably do that first.

Epi/Halo is an excellent comboi'm on week 3 of that combo right now and gained about 5 pounds of muscle so far. zero side effects.
edit: also had bp checked 2 days ago and was perfectly normal. just remember diet and support supplements are very important.
im looking to run a similar cycle. Im looking for lean, dry, mass gains. i was thinking of bridging the products, Halo 3wks bridge the 4th week into epi. stick with the epi to get diced at the end of cycle. i have cycle support 2.0 for liver,cholesterol, clomid for pct as well as X-lean for anti-cortisol and immune booster.
any extra help/ thoughts would be great.
looking forward to hearing about the results man!
Probably the best cycle I have ever run was epi/halo bridged and ran for 7 weeks.
I know this might be kind of an odd question but im looking to run a cycle of x tren/hdrol here soon but im currently running a cycle of natadrol. What I am wondering is would it be safe to bridge tren and hdrol after natadrol and just have a serm to bank on after this cycle. I know that natadrol is still pretty potent but i dont feel like it would be to bad to bridge considering its not anywhere near x tren and hdrol. any comment would be appreciated.
This is interesting, id like to see your plan also.
