I have used OSTARINE and wasn't impressed at all. Minimal gains/results at best.

LGD is very anabolic, but it also lowers your natural testosterone-production, which leeds in direction infertility.
Ostarine was in discussion as "the anti-baby-pill for men"
RAD140 is even used for benefiting the prostate and didn't reduce sperm in rats
YK11 has also very low impact on your spermatogenesis, it simply suggests you body not to limit the muscle mass (which it wants to be less energy wasting, which is good, if you're in an ice-age)

Triptorelin (which imitates GNRH- ordering your brain to start the production of sexhormons) in a low dose starts up your FSH and LH production (they order fats and spermproduction).But several times used the Brain simply stops to produce GNRH (so the brain stops for 4-5 weeks to induce FSH and LH production - your chemically castrated)So little is much and much is nothing.
HMG is a mix of FSH and LH (HCG imitates little bit this in men) so a cocktail of HCG and HMG is also used as a startup, mixed with Testosterone its used for people who are fertile but different castrated like a Hypophyses-Tumor etc. (Hypophyse is the sexhormon central).
At 35 you testis start to go south, and women start to have huge problems to get pregnant with 35 also.Meanwhile we're hardwired to start missing children with 40.So using juice demands of you to learn about your hormone-system (endocrinology).Stupid Bodybuilder have less gains that intelligence-using ones.And really today it's not very complicated to learn.

Yeah you're still young and plenty more to gain before diving in. You'll do what you'll do but I was damn near 250 in weight before I started and Im an old man going 280 now just before my next diet

Go and do wendlers building the monolith and the diet for it for 18 weeks and see where that gets you. Sarms will shut you down just like aas.

Listen to Mack, and LGD will suppress your natural levels pretty hard, and at your age you don't want to screw up your natural test levels and HPTA. At your age I took a natural test booster like tbomb, no2, creatine and worked out only 3 times a week but full body workouts and half the juicers were asking what I was taking. It's all food and training at your age. Get on the track and run some 40 yard sprints til you almost puke a couple times a week, eat 4000 cals and lift like a beast.

I don't know anything about SARMS, but I'll give you +1 for not doing AAS at 22 and researching a safer way to grow. Good luck!

Why can't you use food to bulk? Isn't that what a bulk is? Last I checked a bulk is over 4K calories a day. Are you having problems eating? If you are just eat 3 big ass meals a day with a high protein shake before bed. 1500 calorie breakfast, 1500 calorie lunch, 1500 calorie dinner, 500 calorie protein shake before bed. BOOM you made it. Give that a try and leave the LGD-4033 and other chems out of the picture.
