i think you will find the tabs are called nap50 not nat,
oral only cycles are frowned upon but only because people lose there gains supposedly (read on). not because there supposed to be dangerous,
if you do a short cycle you wont harm yourself infact you will do more harm binge drinking.
short cycles are ok, most use dbol as a kicker for 4 weeks yet they boo people who want to use dbol only saying its dangerous, how's it any more dangerous than them using it as a kicker? it isnt. short cycles are fine.
also on the you will lose your gains lark, again its roid dependent but mostly down to dbol again as you get lots of water weight which makes you look big, once you stop you lose this and people confuse this with losing there gains, it wasnt gains in the first place it was water.
if you can put 30lbs on over say 5 weeks on dbol after pct you could expect to keep half of it, 15lbs in 5 weeks by anyones standards is great so you shouldnt moan but most do.
first cycle will always be the best one (most gains) and most go for a dbol tab kicker with test injected.
ive said in other threads not related to roids though that diet is king, if your on roids with the diet you stated you can only expect one thing and it aint big gains well not the sort you want, try a big shit load of fat.
there not magic drugs you take and get big, people seem to think they are, theres still lots of hard work involved and as stated if you only 10 stone you could add 3 more natural even though it wouldnt be a quick fix.
and tell your mate hes going to shut off his own natural test if he dont quit that shit hes doing, if it aint done right and in a cycle with pct your asking for trouble, dont belie ve all the shit about he'll die thats bollocks theres no reported deaths that have been confirmed from steroids FACT.
WHAT HE WILL DO THOUGH IS **** HIS NATURAL TEST FOR GOOD, basically when he stops it his body wont produce its own no more, say hello to mr i look and act like a big girl.
also lets get the small dick shite out of the way, its a myth, the only thing that can happen and it doesnt happen to everyone is the nads will shrink, they shrink because your brain tells your sack you dont need any because of the amount you have in you from the roids.
once the roids are over with the brain tells the nads to resume and they will be back to normal.
theres a lot of bollocks out there about them mostly to scare you off using them, but you ask any one whos used them and they wont and dont have a bad word about them.
just to add again there not for everyone and its choice but i wont judge anyone who uses, but i will offer advice to people asking and reply especially if there not ready for them and in your case id say your not.
thought id add this after reading lot of google type replies and the stupid non factual replies from some of the people on here who have an opinion on every subject, i think thats only fair as i dont want you to take whats written as gospel from people on here, same goes for me though dont believe me go research it yourself.
