We have set out what the seller says for each product below, plus timing tips, what to expect in the first weeks, when to get help, and how the refund works.

How much Performance Lab should you take, and when?
Performance Lab’s seller publishes standard directions on its Advanced Usage page at performancelab.com. The table below uses those directions. The bottle label is the final word, so read it before your first dose.
| Product | Seller’s directions | Timing and food notes |
|---|---|---|
| NutriGenesis® Multi for Men | 4 capsules a day, best taken as 2 capsules twice a day | With or without food. Avoid taking it within one hour of Caffeine + or other caffeine, which the seller says can reduce absorption of some vitamins and minerals. |
| Omega-3 | 3 softgels with your first meal of the day | Use daily and consistently. |
| Mind Lab Pro® | 2 capsules in the morning before eating | Add 2 more around lunchtime if required. |
| Energy | 2 capsules in the morning or early afternoon | The seller says to take it on an empty stomach. |
| B-Complex | 1 capsule a day | With or without food. The seller says it is best taken in the morning. |
| Flex | 2 capsules daily | For extra joint support, 2 capsules immediately after physical activity. |
| Potassium | 1 to 2 capsules a day | Take around food. |
| Prebiotic | 3 capsules immediately before 1 or 2 meals daily | Take with at least 8 oz (240 ml) of water. |
| MCT Energy Oil | 1 tablespoon daily, as needed | Take it straight or add it to coffee, shakes or smoothies. When used for fasting or calorie-deficit fog, the seller says not more than one serving every 3 hours. |
| D3 + K2 | Check the label for the dose | The seller says vitamins D and K absorb more effectively alongside fat, such as MCT oil or Omega-3. |
| Pre Lab Pro® | Check the label for your starting serving | The seller says the dose can go up to 2 scoops. If you train twice a day, you may take one scoop before each session. The seller says not to exceed 2 scoops within 24 hours. |
| Sleep | Check the label for directions | The product page describes it as a night-time product. |
Tips for taking it well
- Keep it steady. The seller repeats one instruction on most product pages: use daily and consistently.
- Start MCT Energy Oil slowly if your stomach is sensitive. The seller’s graduated plan is 1 teaspoon per serving for 2 days, then 2 teaspoons per serving for 2 days, then a full tablespoon. It can also be taken with a meal that has fat and protein, or sipped slowly over 30 minutes.
- Space out caffeine and the multivitamin. Keep NutriGenesis® Multi for Men at least an hour away from caffeine.
- Pair fat-soluble products with fat. The seller says D3 + K2 and the multivitamin’s vitamins A, D, E and K absorb better with a healthy fat.
What to expect in the first weeks
The seller’s Shipping & Returns page says that “for best results, all supplements should be used in conjunction with a healthy lifestyle, including a healthy diet and regular exercise.” Plan to judge a product over a full container, not a few days. The same page asks you to take the product as directed until the container is empty before you request a refund.
Two side effects are named on the seller’s pages:
- Stomach discomfort with MCT oil. The Advanced Usage page says MCT Energy Oils may cause stomach discomfort in a small number of people with sensitivities. It says upset stomach is far less common with its C8+C10 oil than with coconut oil and oils containing C6 and C12.
- Keto fog. If you are starting a ketogenic diet, the seller says ketosis takes about 3 to 4 days, and some people feel low vitality during the changeover, which it calls “keto-fog.”
When should you stop, or get help?
The seller’s Terms & Conditions ask you to “disclose all supplements in your health regimen to better identify potential interactions, including interactions with prescription drugs or other medical treatments.” If you take prescription medicines, bring the full list to a pharmacist or clinician before you start.
If you feel a reaction you did not expect, stop the product and ask a clinician or pharmacist before you restart. If you are taking Performance Lab for tiredness and it lasts, the MedlinePlus fatigue page says: “If you have been feeling tired for weeks, contact your health care provider.” Cleveland Clinic’s fatigue guide adds that “if an underlying condition causes it, a healthcare provider can usually help you manage it.”
How does the Performance Lab refund work?
The seller’s Shipping & Returns page describes a 30-day guarantee on your first order. It says: “If you don’t see results, we will gladly refund your money (minus any shipping costs).” The steps are:
- What is covered: your first order, up to one container of each individual product. Opening more than one container of the same product means no refund on the extra containers.
- Deadline: submit your claim within 60 days of delivery.
- How to claim: email cs@performancelab.com first. Give your full name, address and order number.
- What you get back: the refund minus shipping costs. The seller says you pay for return postage when you send items back.
- Miss a condition: the seller says it will not be obliged to give a refund.
The same page also lists a separate return window for unused and unwanted items: contact customer support “within 14 days of receiving your order.” That 14-day window and the 60-day guarantee claim window are both on the seller’s page, so ask customer care which one applies to your order before you buy.
Before you order, check these
- Match the directions above to the label on the product you buy.
- Check today’s price and any bundles directly at performancelab.com, since prices and offers change.
- Ask customer care which refund window applies: the help centre lists a customer care line and a contact form on the seller’s help site.
- The seller’s page says its statements “have not been evaluated by the Food and Drug Administration.” You can read the agency’s own information on its FDA dietary supplements page.
