Now then that's some solid reminder for me  Forgot about coco pops. Adding them to my next grocery list. Thanks.

Honey Nut Shredded Wheat currently doing it for me.

I’d rather have a bowl of coco pops

Personally I wouldn't bother. Once the weights get heavy the sessions will be long enough. Last thing I wanted to do was more. 
Focus on getting your lifts from suck to reasonable and forget about the size of your biceps.  Once reasonable then you can decide on which route you take, strength or bodybuilding. 

Iv done this and Iv done that. Iv had high protein and moderate protein. Get your calories in the sweet spot and everything is juuuuuust right 

Apologies I’m in my 30’s a typical meal will be 300-350g turkey breast, mushrooms, onions and 125g basmati rife with curry sauce or 300g rump steak, sauté veg and home made wedges washed down with a pint of milk. Meal 1. ‘Break’ fast if you will is usually 3/4 turkey bacon, 4 eggs and 2 burgen bread toast 

This is how I work it out. Hold on to your hat, it’s very technical......
Sedentary - Multiply BW in lbs by 14.
Fairly active - Multiply BW in lbs by 15. 
Active - Multiply BW in lbs by 16.
That will give you your maintenance cals, five or take. Then add or takeaway 200-300 depending what the goal is. 

Take a week off. See how you feel after that.  If you need 2 weeks off, just do it. Your body will thank you for it. I don’t start inject something peptide or taking some supplement if I’m in pain along with continuation of current training intensity. Makes zero sense. 
 
Taking a break is good mentally too. Especially if you’ve been hitting the strength rep ranges. As I’ve gotten older, I respect & appreciates time away from the  gym. I feel refreshed and excited about returning to the gym after a break. 
 
Start a thread about it to see what works for different people.  Then you can try what you fancy. I feel the main theme will be just to take a break.
 
Longevity in training needs a smart approach.  Can’t keep going all out. Burn out will come a knocking else. 

Agree you probably mean UC-II undenaturated collagen it is like especially for joints and it may help people with arthritis. I think it is in capsules.  However many sources say that hydrolized collagen is also just as good  for your joints, bones, tendons as well as for your skin and hair. There seem to be a lot of different amino acids in that collagen and they all work together. Hydrolized collagen has also been studied the most as far as I know.

Was thinking that too. Or maybe a good deload? I have no deloading experience so far. I might search for some threads here or start a new one about it. Especially now that I'm doing a lot of 5x5 lifts I feel like I might need to deload soon.

Maybe try rehab (plus some time off) for tendon issues. Will serve you better in the long run. 

That's the one I've ordered too! Only in 500 gr bag.

Tbh both of you have made great points here. All read and taken into consideration. Eating as much as I can. Added 5 kg on both Leg Press and Deadlifts today and my knees felt great! (my quads and glutes died a little though ). I've ordered some hydrolized collagen to deal with my elbow tendons so gonna take it  daily  and I am planning to add at least 2.5 kg per week for all my lifts from now on.

That’s a reasonable lift. I train in a municipal and I see plenty benching less than 60. You should still seek further progression before using gear though. 

@BuffPup

Some reading for you...
https://stronglifts.com/5x5/

Tough s**t mate. You don’t get big overnight. Your body isn’t used to heavy weights and if you jump on gear that packs on aLot of muscle before your joints have the time to realise what’s happening, you’ll injure and f**k yourself up. And then you’ll be waiting even longer won’t you. You have a lot of research and learning to do before you consider AAS. 

@BuffPup when I was 20, started lifting, loved it, had 20kg either side Pretty quickly for deadlifts, squats, I wanted to jump on gear and get big. I Lifted for maybe a year and spoke to Gym owner  About gear, he was a ex body builder etc. He sat me down and  was open and honest (as guys above have been), I wasn’t ready. Diet wasn’t good enough, I hadn't been lifting long enough to Really prepare/strengthen my body/joints. It was a hobby For me then but not a lifestyle, my mindset wasn’t ready. I’m on my first cycle now and I’m 30, not saying it takes 10 years but it takes time to learn and be ready so don’t rush into s**t as you’ll just regret it. 

I'd still say after 1 and a half years training your lifts should be higher than what they are mate.
I recommend u find a training program completely based on progression of your lifts that's been tried and tested by hundreds of bodybuilders/powerlifters.
Two I've used are 531 and DC training by Dante Trudel, or follow/read about Jordan Peter's and his methods as they're very similar,or even Dorian Yates. You could try DC but really stick at it for a year and follow the instructions exactly, they're pretty simple.
On DC Everytime you go in the gym you've just got to beat the numbers of the last time you did that exercise on the rotation split and if you dont, you know the problem lies in your diet and/or sleep. I love training this way and imo u make alot more progress than standard volume training (setsxreps)
 

I waited 5 years buddy. Based on what you said I don't think you're ready. 

Buff....pup

And you call yourself buff?!
Pull the other one, you bad melt!!

Nope... I would build up your lifts first.

Work your cals out on tdeecalculator (google it). Then build a diet that fits your cals, oats, lean meat (chicken, mince),  potatoes/rice , berries/zero fat yoghurt, nuts, etc.
