As we inch closer to the generic entry window of 𝗢𝗿𝗮𝗹 𝗦𝗲𝗺𝗮𝗴𝗹𝘂𝘁𝗶𝗱𝗲, the economics remain a tough nut to crack for many generic players.
According to QYOBO https://lnkd.in/dydt9kJG, Semaglutide API prices have declined 𝟲𝟬–𝟳𝟲% since 2020, reaching a corridor of $𝟯𝟯𝟬–𝟰𝟯𝟬/𝗴 by early 2025. But even at $𝟯𝟴𝟬/𝗴, 𝗮 𝟭𝟰 𝗺𝗴 𝘁𝗮𝗯𝗹𝗲𝘁 would still require an API worth $5.32/tablet — far beyond the range of commercial feasibility in GCC.
Let’s analyze the viability using 𝗚𝗖𝗖 𝗺𝗮𝗿𝗸𝗲𝘁 𝗱𝗮𝘁𝗮 (source: Pi Pharma Intelligence https://lnkd.in/d5pqHTZD):

𝗣𝘂𝗯𝗹𝗶𝗰 𝗽𝗿𝗶𝗰𝗲𝘀 𝗳𝗼𝗿 𝗥𝘆𝗯𝗲𝗹𝘀𝘂𝘀 𝟭𝟰 𝗺𝗴 (𝟯𝟬’𝘀 𝗽𝗮𝗰𝗸):
· KSA: $4.06/tab
· UAE: $5.82/tab
· Qatar: $6.52/tab
· Kuwait: $4.61/tab
· Bahrain: $4.19/tab
· Oman: $4.87/tab
· Jordan: $4.96/tab

𝗔𝘀 𝗽𝗲𝗿 𝗦𝗙𝗗𝗔 𝗽𝗿𝗶𝗰𝗶𝗻𝗴 𝗿𝘂𝗹𝗲𝘀, the first generic in 𝗦𝗮𝘂𝗱𝗶 𝗔𝗿𝗮𝗯𝗶𝗮 would likely be listed at ~$𝟮.𝟴𝟰/𝘁𝗮𝗯 (70% of innovator price).

𝗘𝘀𝘁𝗶𝗺𝗮𝘁𝗲𝗱 𝗖𝗢𝗚𝗦 (𝗶𝗻𝗰𝗹𝘂𝗱𝗶𝗻𝗴 𝗳𝗼𝗿𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻, 𝗰𝗼𝗻𝘃𝗲𝗿𝘀𝗶𝗼𝗻 & 𝗮𝗻𝗮𝗹𝘆𝘁𝗶𝗰𝗮𝗹):
~$𝟬.𝟲𝟬/𝘁𝗮𝗯, of which $𝟬.𝟰𝟴 would be the contribution from API.

Therefore, to make the economics work:
The Semaglutide (non-sterile) 𝗔𝗣𝗜 𝘀𝗵𝗼𝘂𝗹𝗱 𝗰𝗼𝘀𝘁 < $𝟯𝟰/𝗴 (𝗶.𝗲., < $𝟯𝟰,𝟮𝟴𝟲/𝗸𝗴).

𝗞𝗲𝘆 𝗜𝗻𝘀𝗶𝗴𝗵𝘁 𝗳𝗼𝗿 𝗚𝗲𝗻𝗲𝗿𝗶𝗰 𝗦𝘁𝗿𝗮𝘁𝗲𝗴𝘆 𝗧𝗲𝗮𝗺𝘀 𝘁𝗮𝗿𝗴𝗲𝘁𝗶𝗻𝗴 𝗚𝗖𝗖:
A viable oral semaglutide business case 𝗱𝗲𝗺𝗮𝗻𝗱𝘀 𝗔𝗣𝗜 𝗽𝗿𝗶𝗰𝗲𝘀 𝘁𝗼 𝗳𝗮𝗹𝗹 𝗯𝗲𝗹𝗼𝘄 $𝟯𝟰/𝗴 — a steep drop from current levels.

Until then, 𝗰𝗼𝗹𝗹𝗮𝗯𝗼𝗿𝗮𝘁𝗶𝗼𝗻, 𝗖𝗗𝗢 𝗶𝗻𝗻𝗼𝘃𝗮𝘁𝗶𝗼𝗻, and 𝗲𝗮𝗿𝗹𝘆 𝗹𝗶𝗰𝗲𝗻𝘀𝗶𝗻𝗴 could bridge the technical and economic challenges.

In the real market, today is 2025/09/09, the recombinant api price is around $90/g. If DMF and WC required, the price is around $130/g.

A manufacturer quoted as below:
​India/Emerging Markets:​​ 95−105/gm min. Not recommended.
​US/EU:​​ Higher (patent premium).
​Canada:​​ Expected 120−140/gm.

Amycretin, developed by Novo Nordisk, is a single-molecule long-acting GLP-1 and amylin receptor agonist. Its mechanism of action achieves weight loss by simultaneously activating both receptors: • GLP-1 receptor activation: delays gastric emptying, promotes insulin secretion, and lowers blood sugar; • Activation of amylin receptors: It directly acts on the central nervous system, inhibits appetite and reduces energy intake. In July 2025, the molecular structure of Amycretin, a GLP-1 series product under Novo Nordisk, was officially disclosed.

The amycretin structure comprises a GLP-1 receptor agonist moiety (dark blue) and an amylin receptor agonist moiety (light blue) connected by a linker region (yellow). The amycretin peptide is acylated with a C18 diacid-based sidechain (white) at position K37 (when employing GLP-1 7-37 numbering).

If you're using GLP-1 receptor agonists (e.g., semaglutide, tirpotide, liraglutide, etc.) – these drugs that are effective in blood sugar control, weight management, and metabolic health, then a scientific nutritional intervention can take your results to the next level!
Why? Because GLP-1 drugs work by regulating appetite, delaying gastric emptying, and improving insulin sensitivity, they can also bring some challenges, such as muscle loss, micronutrient deficiencies, intestinal discomfort, etc. Reasonable nutritional supplementation can not only alleviate these side effects, but also enhance the effect of the drug, so that your health management can get twice the result with half the effort!
Today, we share five core nutritional supplements to provide comprehensive support for your GLP-1 treatment!

Protein powder: prevents muscle loss and maintains metabolic vitality

Why is it particularly important?
GLP-1 drugs significantly reduce appetite, which may lead to insufficient protein intake, while muscle loss can reduce basal metabolic rate, affecting long-term weight loss and physical performance.
Scientific Supplementary Scheme:
Whey protein (fast absorbing) or vegetable protein (easily digestible), 20-30g daily, can be added to breakfast or meals in portions.
The recommended daily protein intake for adults is 1.2-1.6g/kg body weight (for example, 60kg people, i.e., 60*1.2≈72g/day); If you have exercise habits, you can increase your body weight to 1.5-2.0g/kg to help muscle repair.
For example:
1 egg ≈ 6g protein
100g chicken breast ≈ 30g protein
100g tofu ≈ 8g protein
1 cup milk ≈ 8g protein

Fish oil (Omega-3):

Anti-inflammatory and heart-protecting, enhance insulin sensitivity
Key role: Users of GLP-1 often have a risk of metabolic syndrome.
Omega-3 (EPA+DHA) can:
✔ reduce systemic inflammatory response
✔ improve dyslipidemia (lower triglycerides)
✔ synergistic enhance insulin sensitivity
Precise supplementation suggestions:
Prioritize high-purity fish oil (EPA+DHA≥60%), with a daily intake of 1000-2000mg. Eating deep-sea fish (salmon, sardines) 2 to 3 times a week is a natural supplement.

Probiotics:

Optimizes gut health and relieves drug side effects
Necessity Analysis:
GLP-1 drugs may cause:
Gastrointestinal discomfort (nausea, bloating)
Imbalance of gut flora
Probiotics can:
Improves digestion and absorption
Enhances intestinal barrier function
Regulates the brain-gut axis (indirectly affects appetite)
Strain Selection Guidelines:
Focus on clinically validated strains such as Bifidobacterium lactis HN019 and Lactobacillus rhamnosus GG strain.
Supplement 100-30 billion CFU daily, recommended to take on an empty stomach before breakfast.

Cellulose:

Dual regulation of blood sugar and appetite
In-depth interpretation of the mechanism of action:
Soluble fiber (e.g., β-glucan, pectin): forms a gel to delay gastric emptying and prolongs satiety in synergy with GLP-1.
Insoluble fiber (e.g., cellulose, lignin): promotes intestinal motility and prevents constipation (common side effect of GLP-1).
Practical plan:
Total daily dose of 25-38 g, preferably from whole foods (oats, chia seeds, legumes).
Cellulose supplements, which can be gradually increased to avoid flatulence caused by sudden large intake.

Multivitamins & Minerals:

A critical line of defense to fill nutritional gaps
Risk warning:
The gastrointestinal effects of a low-calorie diet + GLP-1 can lead to:
Decreased absorption of vitamin B12
Insufficient vitamin D (affects weight loss)
Magnesium/zinc deficiency (associated with insulin resistance)
Targeted Supplementation Strategies:
Choose a multivitamin with active B12 (methylcobalamin).
Additional attention is paid to vitamin D3 (2000IU/day) and magnesium (200-400mg/day).

Tips：

Personalized adjustments are more effective!
✔ Consult a doctor/dietitian: adjust the dosage according to your own situation.
✔ Gradually: Cellulose and probiotics in particular to avoid gastrointestinal upset.
✔ Pair it with a balanced diet: high-quality protein + healthy fats + low GI carbohydrates for better results!
