Im 39 and have tried a few test boosters and since this question comes up frequently I thought I would help a few people out. Been lifting for about 6 yrs with no more than a 2 week break.
1. Tribulus (0/10)-NO benefits for me what so ever.
2. Animal Stack (6/10)-Did two cans in a row. Alpha feeling was great but no real gains as far as strength or size.
3.Bioforge(older version)/Ebol (8/10)-Did 2 bottles in a row of each. Lost some body fat with this and decent gains in size/strength. Over all enjoyed it and would do it again if the price was right.
4.Testopro/Stoked (10/10)-WOW! All I can say is WOW! I just finished my last set of pills before todays workout. I did 2 of each in the morning and 2 of each before bed. Only 1 bottle of each (30 days). Strength gains were insane. PR's every week! Gained about 6 lbs and waist is the same. Muscles are NOTICEABLY harder and fuller. I wished I couldve run this for another month. WILL 100% do this again in the future.
HOPE THIS HELPS SOMEONE!
