typical gains are 8-15lb of LBM, increase in strength, and a lot of guys notice that bodyfat stays the same or slightly decreases. it is one of my favorite designer steroids being sold on the open market right now. def. love me some havoc.
i agree these 2 are hard to compare but with you being older than a lot of users, you may actually find Prime a lot more beneficial and gains more noticeable than some of the younger users. if you aren't strapped for cash i would recommend using Prime during cycle to help avoid some shutdown that may occur or save for PCT or use as a standalone later ... your call but you cant go wrong either way IMO.
Ok so lets not compare the products lets compare the results instead. You say 8-15 lbs muscle gain that is more than Prime the most I have seen in 30 days from the logs is 10 or 11 and the lower end would be 6 and it being a herbal there are probably more non-responders. Now there is no pct with Prime so you could take it longer, what we don't know at this time is do people continue to gain after 30-40 days of Prime. Someone also stated that they kept 75% of their gains on havoc. We don't really know how much is kept when in Prime but I am going to guess that it may be significantly higher. Maybe not as I can't say for sure, it hasn't been out long enough. This something to consider however because to takes 8-15 down to 6 to 12 which is still a little better but not that much. Two factors to consider.
You say that the body fat stays the same on Havoc, most Prime users lose body fat lets call it equal.
Now strength gains... my son put 40 lbs on the bench in 30 days on prime for 5 reps... it seems Havoc may have a slight edge here as well.
Yes I did it I compared the results... saying you can't compare the two is just being obtuse. You just take what happens on one and compare it to what happens on the other. These are the facts, I pick Prime, I will never do another product that requires I take a bunch of other products to recover. I am also afraid at my age of prostate problems.
