Hi @Jane Reno , We have a full course in the classroom titled "How to Inject Safely."

@Jane Reno this thread is about NAD so you may want to create a new post so the community knows what you are talking about to give you the best feedback.

In my research I would keep the test as the baseline and the NAD+ doesnt have to be cycled. You could research MK-677 for 4 weeks then CJC-1295 no DAC/Ipamorelin works well for adding lean muscle, I have seen the best results using 250mcg/250mcg in the AM when you wake up and then again before you train. Also when you stop researching MOTS-c, look into researching SS-31 for 4 weeks at 2mg a day to help with mitochondria repair.

For advanced researchers you could add IGF-1 LR3 for 3 weeks: 25 mcg on training days, post-workout (subQ). Just have to eat more carbs.

@Alisa Kotvas Based on your goals you could stack 250mcg of BPC-157 daily, 2.5mg of TB-500 every 5 days and 1.25mg of GHK-cu daily. This will help with tissue and skin repair, collagen, and anti-inflammatory. I would start low with with 25-50mg of NAD+ three times a week along with 2-4 mg of SS-31 for 4-6 weeks.. This will help with mitochondrial repair and ATP production. If energy is improving but you want additional support for Phase 2 (Weeks 7-12) Add: MOTS-c, 5-10 mg twice weekly in the AM to improves mitochondrial metabolism. Its a excellent exercise signaling peptide and helps metabolic flexibility and works best after SS-31. Then consider: Epitalon, 5 mg nightly for 20 days. Only do this every 6-12 months This is probably the best longevity peptide available from a safety standpoint. Instead of adding Tesamorelin, I'd consider compounds with more direct evidence for cognitive benefits like Pinealon, Dihexa or Semax with Selank. I'd only add Tesamorelin if I had, high visceral fat, poor sleep or age-related GH decline with documented low IGF-1. If you are considering Reta but dont need it for fat loss, there are other benefits of taking low dose like .5mg-1mg per week as it helps keep blood glucose level and some new research has shown longevity properties. The trick to keeping muscle with it is to eat at least 1g of protein per lb of bodyweight and lift weights at least 4 times per week.

Just make sure your taking in enough eletrolytes and add zinc and collagen protein and Vit C to your daily intake too. These are the tools that help the GHK do a better job.
