Make sure you get the right testosterone supplement for you.Check Best List
In the interest of being as fair as possible to the Primasurge testosterone booster, we're judging them based on a 2 capsule daily intake, not a one capsule serving.
Ashwagandha root extract 500mg - Ashwagandha is a pretty standard inclusion for any testosterone booster supplement. It's well backed to raise testosterone levels , and reduce several symptoms of low testosterone. Particularly those symptoms which can themselves lower testosterone levels making matters worse, such as stress (build up of cortisol) and poor sleep. Typically speaking we'd prefer to see 600mg, but 500mg should be fine for average size men, but not ideal for anyone on the larger side. It does also have the benefit of Ashwagandha being particularly good for raising overall mood.
Safed Musli 250mg - Safed musli has been shown to improve semen quality in males, but does note improve testosterone production in statistically significant ways. Good for a male enhancement product, not so much for a test booster.  And if something was to be included for a libido boost alone, we'd have recommended maca over musli.
Shilajit Extract 250mg - There's one small study available that backs shilajit, that doesn't mean it doesn't work at all, but we can't take one 20 man study as a reference point for it's efficacy . It is however in the same dose as said trial, so it could be fine.
Longjack 200mg - Longifolia Extract is another common inclusion in mid range natural testosterone booster supplements. It doesn't make it into all of the best testosterone boosters, despite having a reasonable amount of backing showing that it does in fact work, it's effects were relatively middling and there are better more effective research supported ingredients available.  200mg is the bottom end of the effective supplementation range for testosterone production, although we'd prefer Longjack to be dosed a little higher in most cases.
Boron 10mg - This is a great inclusion, boron makes it into almost all of the best test boosters it's quite effective and doesn't take up too much capsule space, it's relatively inexpensive and we don't typically get a lot of it in our diets, so we like to see this. It's been shown to raise test levels, improve joint health and improve athletic performance so it's a must have for any gym focused booster. 
Bioperine 10mg - A standard inclusion in a lot of supplements bioperine helps the body absorb nutrients more efficiently. It doesn't raise testosterone directly, but there's nothing wrong with it's inclusion. It's more essential in higher dosed supplements, but again, it's fine in Primasurge.
PrimaSurge isn't bad, it's just mediocre. Sure it can boost testosterone a little bit, can probably help you with some lean muscle growth and fat loss there's just a lot better supplements available.
It's OK for its price point and if it included a decent vitamin blend then it would arguably be good. It just doesn't hold a candle to the supplements you can get for $15 a month more and most men would benefit more from taking a multivitamin instead.
In short Primasurge has a couple of testosterone boosting ingredients in OK doses, but if you're looking for the best testosterone booster for maximum muscle growth, this is not the supplement for you. If you're after something budget and already have a multivitamin you take, then you could do worse.
