former player here:
My take:
1) I'd go with a short ester test. makes life easier IMO (pct, dosing, adjustments). Test Prop is my #1 athlete choice- no bloat, you can hone in your dosing in real time, clears quick for drug tesing which allows for a quicker PCT. etc/etc..
2) Dbol does't seem like a natural fit for a Defensive back. many reasons. The back pumps and bloating fucking destroy training outside the weight room. Feel like you are carrying around water bottles and tons of dead weight. back hurts during high knees in warm ups.. I hate it. No dbol or abombs IMO. Makes you gain 10lbs of water and 5-10 lbs of muscle in a month, but you have plenty of time IMO.
3) Which brings me to my two favs- Winny. I know everyone says my joints ache. wa, wa, wa. But winny, for Track athletes kicks ass in terms of endurance on the track. Lets you get nasty with drills and field work. At safety thats all we should be focusing on. Anyone who has trained on good winny can tell you this. You just keep going. And he will and should be doing a ton of running. Run that for 4 weeks and rotate to t-bol. Designed for german weight class athletes so it keeps you lean. Dbol w/out the bloat.
4) just bang back and forth from t-bol/winny/tbol/off/ tbol/winny stack/ off/ for the whole cycle. with the prop underneath it. ( You wanna get medieval add in some anavar.)
5) Tren not good IMO, for athletes where cardio is involved (football qualifies) - makes you effing-tired. Tren cough? not good for football/mma/boxing
6) tell ur guy don't trip on the weight, that shit will come screaming back, and this is a good opportunity to add quality functional athletic weight. So take it slow and go for SPEED. I'm sure he knows this, but he feels feeble now and wants his weight back. It the weight will come, but add quality. DBOL puff is not quality.
If he's only down 20 lbs (10 will probably restore instantly ) and muscle memory is real thing as well.
7) Back in the late 90's we used to cut our cycles short and go right into camp as our natural HTPA was shut and steroids were leaving the system. Of course we never considered this. So exactly when we needed it most - our endogenous test was gone. So cut the cycle short, do PCT, and let those drugs clear (they are banned substances as well), and make sure he goes to camp with his natural test close to restored. WE used to fucking come off with no pct during triple sessions. What a fucking nightmare. Stupid we were.
8) ultimately you wanna go slow and steady no so you can keep you're gains through a super catabolic 4 months of camp/season.
Test prop/winny!!!!!
(quality HGH baseline in small amounts wouldn't kill you) but not necessary.
